  • Overall, Playwright is a powerful framework with many benefits that makes it ideal for web automation testing.

Playwright Vs GitHub

Playwright and GitHub are two very different technologies, and it would not be accurate to compare them directly. However, here is a brief overview of what each technology is and how they differ:

Playwright is an open-source test automation framework that was developed by Microsoft to provide a more modern and efficient approach to automation testing. It supports multiple browsers, including Chromium, Firefox, and WebKit, as well as native mobile emulation of Google Chrome for Android and Mobile Safari. Playwright provides easy-to-use APIs, powerful debugging capabilities, and supports both headed and headless modes for testing.

On the other hand, GitHub is a web-based platform that provides version control and collaboration for software development projects. It allows developers to store and manage their code in repositories, collaborate with other developers, and track changes to their code over time. GitHub also offers features such as issue tracking, pull requests, and continuous integration and deployment (CI/CD) tools.

To conclude, we believe playwright is an excellent automation tool for modern web applications. It enables you to write automated tests that describe web automation scenarios and play them out in a browser. This allows you to automate your web applications and web-based user experience - all from one place, as well as execute your automation tests quickly. If you’re looking for a test automation solution that can help you write test cases faster and save time on repetitive tasks, playwright is an optimal choice for your organization.

What is Playwright?

Theo Vasilis

Why use Playwright?

We all know that technology moves fast, but even by modern standards, the rapid rise of Playwright is impressive.

Microsoft released Playwright in 2020 as an open-source Node library to automate Chromium, Firefox, and WebKit with a single API. Today, Playwright is one of the most popular frameworks for web automation, testing, and scraping. It provides automated control of a web browser with a few lines of code, making it particularly useful for data extraction, end-to-end testing, automating web page interaction, taking screenshots of web pages, and running automated tests for JavaScript libraries.

While similar to Puppeteer , Cypress , and Selenium , there are some differences. Let’s find out what they are.

Is Playwright a headless browser?

Not exactly. Playwright can be run in headful or headless mode (without a graphical user interface). By default, Playwright runs in headless mode, which means you won’t see what is happening in the browser when you run your script, but it will run faster. When you write and debug your scripts, it’s advisable to disable headless mode so you can see what your script is doing:

On the other hand, if performance is the most important thing for you, headless mode is the way to go since headless browsers are quicker than real browsers.

What about Puppeteer and Selenium?

Speak of headless browsers, and the names Puppeteer and Selenium immediately spring to mind. So, how do these compare to their younger sibling? Puppeteer supports only JavaScript and TypeScript and works with Chromium, with experimental support for Firefox. Playwright supports Chromium, Firefox, and Safari with WebKit. You can use many programming languages with Playwright and one extra language with Selenium (Ruby). But Playwright’s greatest advantage over Selenium is its auto-waiting function.

What languages does Playwright support?

Playwright works with some of the most popular programming languages, including JavaScript, Python, Java, and C#. Its support of Chromium, Firefox, and WebKit provides a wide range of cross-browser automation and web testing capabilities.

What platform does Playwright support?

Playwright is a cross-platform framework. The browser binaries for Chromium, Firefox, and WebKit work across three platforms: Windows (and WSL), macOS (10.14 or above), and Linux (though you may need to install additional dependencies, depending on your Linux distribution).

How do I get started with Playwright?

One thing that isn’t said enough about Playwright: its documentation is superb. There you will find out how to install Playwright to get started.

You can install the VS Code extension . After installation, open the command panel and type Install Playwright . Alternatively, you can use the command line interface (CLI) and install Playwright using the appropriate package manager for your language. For example, NPM with Node.js:

That will give you the browsers and files you need to begin:

The tests folder contains a basic example test to get you started and the tests-examples folder contains a more detailed example, with tests written to test a todo app.

Alternatively, you can simply add Playwright to your existing project by calling:

Why use Playwright for web automation and testing?

1. faster communication with the chrome devtools protocol.

Most automation solutions use the WebDriver protocol to communicate with Chromium browsers, but Playwright provides much faster and more straightforward communication with the Chrome DevTools protocol . But Playwright isn’t just for Chrome and Edge and Playwright can be configured to test sites in Firefox and Safari, as well.

2. The auto-waiting function

Cross-browser and cross-language support aside, the auto-waiting function is Playwright’s greatest advantage over Puppeteer and Selenium. You don’t have to figure out when something is clickable because Playwright performs that action for you. You can emulate mouse clicks by using await page.click() , and wait for actions in the browser to finish by using convenient APIs like await page.waitForSelector() or await page.waitForFunction() .

This unique automatic waiting feature eliminates the need to write custom waits or sleep statements in your test scripts. That means you can focus on writing high-quality tests instead of worrying about writing the perfect waiting logic.

3. Record scripts with Codegen

The Playwright documentation includes a test generator that shows you how to record your scripts with Codegen. You just need a single CLI command to kick off:

This will open up an interactive browser and the Playwright inspector. Every action in the browser will be recorded in the inspector. You can then replay and adjust the generated script. In other words, Playwright generates test script code based on your interaction with the page. That means you can author tests out of the box without having to write the script manually.

4. Great debugging capabilities

Playwright has some excellent debugging features. You can debug scripts while you run them, which is handy during local development, and you can also analyze and debug failed tests. You can open Playwright Inspector to enable debug mode with npx playwright test -- debug to debug all tests or npx playwright test example -- debug to debug one test. Alternatively, you can set the PWDEBUG environment variable to run your scripts in debug mode.

5. Native mobile emulation

Playwright supports native mobile emulation, which means you can test your web applications on mobile devices without having to set up an actual device. Playwright can emulate Safari on iOS as well as Android devices. Playwright's test runner provides numerous predefined configurations, making it easy to test your web application on multiple devices and screen sizes to ensure that it works as expected for all users without having to manually set up each configuration.

6. Comprehensive reports

Playwright provides comprehensive reporting options for test results. You can:

a) Export results as a machine-readable JSON file.

This is useful if you want to integrate Playwright tests into a larger test suite or if you want to programmatically analyze the results.

b) Export the results as a stylish HTML page.

This is a great option if you want to share the test results with other members of your team or with stakeholders. The HTML report includes detailed information about the test runs, including the number of passed and failed tests, the duration of each test, and any errors that occurred during the test run.

Why use Playwright for web scraping?

We’ve touched upon the brilliance of Playwright when it comes to web testing and automation, but its capabilities can also come in very handy when it comes to web scraping and data mining. Here’s why:

It can be very difficult to scrape some websites with regular HTML tools. Dynamic pages and browser fingerprinting are two of the biggest challenges. Playwright’s headless mode helps overcome these problems.

1. Loading dynamic pages

When it comes to pages loaded dynamically with AJAX or data rendered using JavaScript, you’ll need to render the page like a real user. HTML scrapers can’t do that. Headless browsers can. So, in such cases, you’ll need web scraping tools like Playwright Scraper or Puppeteer Scraper to load the page, execute its JavaScript, and scrape the required data.

2. Combatting browser fingerprinting

Some websites now use fingerprinting to track users and block scraping bots. A scraper that uses a headless browser can emulate the fingerprint of a real device. Without a headless browser, it’s nearly impossible to pass the various anti-bot challenges that block your access to a website. This makes using Puppeteer or Playwright Scraper your best bet when getting blocked.

Also, you can go even further and develop your own web scraper with Crawlee , a Node.js library that helps you pass those challenges automatically using Puppeteer or Playwright.

Emulating mobile devices

Puppeteer and Playwright control headless desktop browsers that can also emulate mobile devices. And while device emulation can’t replace testing on mobile devices entirely, it’s a practical and quick-to-setup approach to testing mobile scenarios.

Device emulation is well suited to test if your site behaves correctly across multiple viewport sizes and correctly handles user-agent strings. But if your site relies on device-specific browser features, an iPhone emulation running in a Chromium browser might lead to false positives.

This guide explains how to define viewport sizes, device pixel ratio and user-agent strings using Playwright and Puppeteer.

Defining the user agent string

If your site parses the user agent string to serve a different experience to mobile users, define the userAgent in your automation scripts.

Defining viewport size and pixel density

If your site follows responsive web design practices and renders elements depending on device viewport size, define a mobile viewport and pixel density.

Use built-in device registries

Playwright and Puppeteer include a built-in device registry to access mobile device characteristics quickly.

how does playwright work

Table of Contents

When you pick a test automation tool for your project, what are the most important features you look for?

  • Ease of developing and maintaining scripts
  • Fast and reliable test execution with no flakiness
  • Support web, mobile, API, and parallel testing
  • An interactive test runner
  • In-depth test failure analysis
  • Cross-browser testing
  • Support for keyword & data-driven testing
  • Language support like Javascript, Typescript, Java, Python, etc
  • DevOps integration with builds
  • Intuitive test reporting
  • Open-source, etc.

muuktest_demo_cta

The first tool that most test automation engineers would think of is Selenium. However, an experienced engineer would know Selenium has its limitations. Enormous timeout, sync, and page load issues add up to the flakiness of the tests.

What about modern-day testing tools like Cypress or Puppeteer?

If you want to write isolated automated web component tests, Cypress.io is good as it offers many features to help you. However, the limitations outweigh the benefits for true end-to-end purposes. I wanted to like Cypress, and it does have a nice interface, but writing tests in Cypress has been a constant headache for me. The extensive use of plug-ins to cover its failures explains the current state of Cypress.

On the other hand, Puppeteer by Google is a node library that provides a high-level API that works only with  Chrome or Chromium  and does not support other browsers. Considering the fact that cross-browser testing must be conducted across platforms using multiple programming languages, Puppeteer would not be an ideal solution.

So is the case with other so-called no-code/AI-based test automation tools. Despite its strongly-worded marketing material, these tools don’t work as expected when pushed to the limits.

What if we combine all the good features of Cypress and Puppeteer, remove the flakiness associated with Selenium, add some no-code/AI features and create a brand-new tool?

Enter Playwright.

What is Playwright and how does it work?

Playwright is an open-source, NodeJS-based framework for web testing and automation. It allows testing  Chromium ,  Firefox , and  WebKit  with a single API. Playwright is built to enable cross-browser web automation that is ever-green, capable, reliable, and fast.

Playwright, which has all the features of a good test automation tool listed at the beginning, was developed by the authors of Puppeteer and maintained by Microsoft. Playwright is compatible with Windows, Linux, and macOS and can be integrated with major CI/CD servers such as Jenkins, CircleCI, Azure Pipeline, TravisCI, GitHub Actions, etc. In addition, Playwright supports multiple programming languages such as  TypeScript ,  JavaScript ,  Python ,  .NET , and  Java , giving more options to QAs writing test scripts. It also supports native mobile emulation of Google Chrome for Android and mobile Safari.

Playwright has many great features, but my favorite by far is Auto-Wait. Playwright waits for elements to be actionable before performing actions. It also has a rich set of introspection events. The combination of the two eliminates the need for artificial timeouts — the primary cause of flaky tests. When the tester runs a Playwright test script, the UI is readied at the backend before the test interacts with web elements.

Now let’s get hands-on and look at some of these other amazing features. Of course, it will be difficult to explain all the features of Playwright in one article, so I will showcase some of my favorites.

1. Ease of Installation, Configuration, and Test Execution

Let’s start by installing Playwright.

Installing playwright

Selecting the required options installs Playwright in the chosen directory.

Once the installation is complete, a new Playwright project is created with the below structure.

Playwright project structure

And that’s it! You are ready to create/run tests.  How easy was that?

‘Package.json’ contains the project dependencies, and ‘playwright.config.ts’ contains project settings like timeout, browser configuration for the project, etc.

The project comes with an example test, ‘example.spec.ts.’ Let’s execute this test to verify everything is working fine. To execute the test, run the command:

‘npx playwright test example.spec.ts’

Test Example

As you can see, 75 tests in ‘example.spec.ts’ were executed in less than 2 minutes using three browsers Safari, Firefox, and Chromium.  That’s how fast Playwright is!

Playwright has a built-in reporting tool. Let’s look at the test report. To open the report, run the command:

‘npx playwright show -report’

This opens up an interactive report on a new browser page.

interactive report on a new browser page

You can click on each test to see the execution steps in detail and their results.

Playwright tests are, by default, executed in headless mode. To change this, add headless: false in ‘playwright.config.ts’ as shown below. I have also commented out Firefox and Safari browser configuration so that tests only run in Chrome browser now.

playwright test

Let’s execute the test again.

playwright test

25 tests were executed in ‘headless=false’ mode using 1 worker node (Chrome). It only took 27 seconds to complete the execution.

2. Parallel Testing in the Same File

 Another important feature of Playwright is parallel testing. Unlike other tools that support parallel testing only when the tests are in different files, Playwright supports parallel testing of tests in one single file.

By default, test files are run in parallel. To disable parallelism, we must limit the number of  workers to one .

By default, tests in a single file are run in order in the same worker process. We can group tests with  test.describe.parallel(title, callback) . To run tests in a single file in parallel.

how to group tests

Upon execution, 5 workers are spun up, and tests are executed in parallel:

parallel executed tests

Test execution time was reduced to 16 seconds as opposed to the above sequential execution scenario, which took 27 seconds to complete.

3. Locators

Locator s are the central piece of Playwright’s auto-waiting and retry-ability. In a nutshell, locators represent a way to find element(s) on the page at any moment.

To demonstrate Locators and other features of Playwright, I wrote a simple test that extracts the price of a product from an Amazon page.

You can get the project code from my Git repository at this link .

Simple test

Upon execution, the test will run in Chrome, open up the product page in Amazon, extract the price and display it in the console.

Notice that I am using ‘locator’ instead of the conventional element handle ($) to find web elements. The difference between the  Locator  and  ElementHandle  is that the latter points to a particular element, while Locator captures the logic of how to retrieve that element.

4. Debug Using the Inspector Tool

Next, let me demo the  Inspector  tool by running the above test using a different command:

‘PWDEBUG=1 npx playwright test amazon.spec.ts’

inspector tool demo

This opens up the inspector tool alongside the browser window and waits for me to click on the Resume button to perform the next step. With the Inspector tool, we can debug each line of code and see how the code works in real time on the browser.

Clicking on the ‘Explore’ button lets us hover over any web element on the web page, and clicking on any element on the page gives us the element locator, making it easier for us to find element paths.

mobile safari playwright

Highlighted element’s locator is displayed below it.

5. Test Generator

Playwright Code gen can generate tests out of the box. You can record UI interactions on-screen, and Playwright will generate the code for the user interactions. Codegen will attempt to generate resilient text-based selectors.

To open code gen, run the command:

‘npx playwright codegen amazon.in’

Start interacting with UI elements, and you will see Playwright generating code for it.

Gif link (Original content)

Isn’t that impressive? But that’s not the best part of Code gen. You can even convert the generated code to JavaScript, Java, Python, or C# automatically.

6. Test Trace Viewer

Playwright Trace Viewer is a GUI tool that helps explore recorded Playwright traces after the script runs.

To switch on the Trace viewer, Set the trace: ‘on’ option in the test configuration file. This will produce a trace.zip file for each test.

Selecting each action reveals:

  • action snapshots,
  • action log,
  • source code location,
  • network log for this action

7. Continuous Integration

Playwright tests can be executed in CI environments. While creating a project, Playwright can generate a GitHub Action Workflow .yml file for you. You can use this to start with GitHub Action CI set up and run tests in any cloud OS like Ubuntu, Windows, or Mac. You can also run Playwright in Docker.

playwright test

Like GitHub Actions, you can integrate Playwright with other CI servers like Jenkins, Azure pipelines, GitLab, CircleCI, etc.

Playwright can even connect to   Selenium Grid Hub , which runs Selenium 4.

Playwright is an amazing framework to explore, and it’s getting better and better by adding new features in its monthly releases. Since its inception, it has evolved a lot and has a growing community of users. However, I should say this article covered only the tip of the Playwright iceberg. There are a lot of other cool features of Playwright that you should explore, and I hope this article will encourage you to do that.

Debugging Tests

Vs code debugger ​.

We recommend using the VS Code Extension for debugging for a better developer experience. With the VS Code extension you can debug your tests right in VS Code, see error messages, set breakpoints and step through your tests.

running test in debug mode

Error Messages ​

If your test fails VS Code will show you error messages right in the editor showing what was expected, what was received as well as a complete call log.

Live Debugging ​

You can debug your test live in VS Code. After running a test with the Show Browser option checked, click on any of the locators in VS Code and it will be highlighted in the Browser window. Playwright will also show you if there are multiple matches.

live debugging in VS Code

You can also edit the locators in VS Code and Playwright will show you the changes live in the browser window.

Picking a Locator ​

Pick a locator and copy it into your test file by clicking the Pick locator button form the testing sidebar. Then in the browser click the element you require and it will now show up in the Pick locator box in VS Code. Press 'enter' on your keyboard to copy the locator into the clipboard and then paste anywhere in your code. Or press 'escape' if you want to cancel.

Pick locators

Playwright will look at your page and figure out the best locator, prioritizing role, text and test id locators . If Playwright finds multiple elements matching the locator, it will improve the locator to make it resilient and uniquely identify the target element, so you don't have to worry about failing tests due to locators.

Run in Debug Mode ​

To set a breakpoint click next to the line number where you want the breakpoint to be until a red dot appears. Run the tests in debug mode by right clicking on the line next to the test you want to run.

setting debug test mode

A browser window will open and the test will run and pause at where the breakpoint is set. You can step through the tests, pause the test and rerun the tests from the menu in VS Code.

Debug in different Browsers ​

By default debugging is done using the Chromium profile. You can debug your tests on different browsers by right clicking on the debug icon in the testing sidebar and clicking on the 'Select Default Profile' option from the dropdown.

debugging on specific profile

Then choose the test profile you would like to use for debugging your tests. Each time you run your test in debug mode it will use the profile you selected. You can run tests in debug mode by right clicking the line number where your test is and selecting 'Debug Test' from the menu.

choosing a profile for debugging

To learn more about debugging, see Debugging in Visual Studio Code .

Playwright Inspector ​

The Playwright Inspector is a GUI tool to help you debug your Playwright tests. It allows you to step through your tests, live edit locators, pick locators and see actionability logs.

Playwright Inspector

Run in debug mode ​

Run your tests with the --debug flag to open the inspector. This configures Playwright for debugging and opens the inspector. Additional useful defaults are configured when --debug is used:

  • Browsers launch in headed mode
  • Default timeout is set to 0 (= no timeout)

Debug all tests on all browsers ​

To debug all tests run the test command with the --debug flag. This will run tests one by one, and open the inspector and a browser window for each test.

Debug one test on all browsers ​

To debug one test on a specific line run the test command followed by the name of the test file and the line number of the test you want to debug, followed by the --debug flag. This will run a single test in each browser configured in your playwright.config and open the inspector.

Debug on a specific browser ​

In Playwright you can configure projects in your playwright.config . Once configured you can then debug your tests on a specific browser or mobile viewport using the --project flag followed by the name of the project configured in your playwright.config .

Debug one test on a specific browser ​

To run one test on a specific browser add the name of the test file and the line number of the test you want to debug as well as the --project flag followed by the name of the project.

Stepping through your tests ​

You can play, pause or step through each action of your test using the toolbar at the top of the Inspector. You can see the current action highlighted in the test code, and matching elements highlighted in the browser window.

Playwright Inspector and browser

Run a test from a specific breakpoint ​

To speed up the debugging process you can add a page.pause() method to your test. This way you won't have to step through each action of your test to get to the point where you want to debug.

Once you add a page.pause() call, run your tests in debug mode. Clicking the "Resume" button in the Inspector will run the test and only stop on the page.pause() .

test with page.pause

Live editing locators ​

While running in debug mode you can live edit the locators. Next to the 'Pick Locator' button there is a field showing the locator that the test is paused on. You can edit this locator directly in the Pick Locator field, and matching elements will be highlighted in the browser window.

live editing locators

Picking locators ​

While debugging you might need to choose a more resilient locator. You can do this by clicking on the Pick Locator button and hovering over any element in the browser window. While hovering over an element you will see the code needed to locate this element highlighted below. Clicking an element in the browser will add the locator into the field where you can then either tweak it or copy it into your code.

Picking locators

Actionability logs ​

By the time Playwright has paused on a click action, it has already performed actionability checks that can be found in the log. This can help you understand what happened during your test and what Playwright did or tried to do. The log tells you if the element was visible, enabled and stable, if the locator resolved to an element, scrolled into view, and so much more. If actionability can't be reached, it will show the action as pending.

Actionability Logs

Trace Viewer ​

Playwright Trace Viewer is a GUI tool that lets you explore recorded Playwright traces of your tests. You can go back and forward through each action on the left side, and visually see what was happening during the action. In the middle of the screen, you can see a DOM snapshot for the action. On the right side you can see action details, such as time, parameters, return value and log. You can also explore console messages, network requests and the source code.

To learn more about how to record traces and use the Trace Viewer, check out the Trace Viewer guide.

Browser Developer Tools ​

When running in Debug Mode with PWDEBUG=console , a playwright object is available in the Developer tools console. Developer tools can help you to:

  • Inspect the DOM tree and find element selectors
  • See console logs during execution (or learn how to read logs via API )
  • Check network activity and other developer tools features

This will also set the default timeouts of Playwright to 0 (= no timeout).

Browser Developer Tools with Playwright object

To debug your tests using the browser developer tools start by setting a breakpoint in your test to pause the execution using the page.pause() method.

Once you have set a breakpoint in your test you can then run your test with PWDEBUG=console .

Once Playwright launches the browser window you can open the developer tools. The playwright object will be available in the console panel.

playwright.$(selector) ​

Query the Playwright selector, using the actual Playwright query engine, for example:

playwright.$$(selector) ​

Same as playwright.$ , but returns all matching elements.

playwright.inspect(selector) ​

Reveal element in the Elements panel.

playwright.locator(selector) ​

Create a locator and query matching elements, for example:

playwright.selector(element) ​

Generates selector for the given element. For example, select an element in the Elements panel and pass $0 :

Verbose API logs ​

Playwright supports verbose logging with the DEBUG environment variable.

For WebKit : launching WebKit Inspector during the execution will prevent the Playwright script from executing any further and will reset pre-configured user agent and device emulation.

Headed mode ​

Playwright runs browsers in headless mode by default. To change this behavior, use headless: false as a launch option.

You can also use the slowMo option to slow down execution (by N milliseconds per operation) and follow along while debugging.

Apple to let iPhone users delete Safari, easily transition to Android

A pple will soon be making significant changes to its mobile platforms in response to new regulations in the EU called the Digital Markets Act (DMA).

Thanks to the DMA, Big Tech companies identified as "gatekeepers" must open up their core platforms to competition or third-party alternatives. Case in point: Apple can no longer monopolize app distribution on iOS in the EU with the App Store. This means, for example, that developers can distribute their apps through alternative application marketplaces on iOS, allowing them to dodge Apple's App Store content policies. 

Apple unveils its first changes under the DMA

By now, you've likely heard about Apple allowing App Store competition in Europe. Apple has been criticized by Microsoft, Meta, Epic Games, and Spotify for rules and policies pertaining to these  "alternative marketplaces." (Apple has instituted new, controversial DMA-related policies regarding Apple's revenue share models, which has been the focus of its peers' criticisms.)

However, Apple is being compelled to make other lesser-known changes to iOS that you may not have yet been aware of.

On Thursday, the day the DMA officially went into effect in the EU, Apple published a compliance report detailing some of the upcoming changes it's making to its platforms due to these new regulations.

Here are some of the most notable changes iPhone users in the EU can look forward to, brought to you by the DMA:

Browser choice

After EU users update to iOS 17.4, they will be presented with numerous web browser options available in their market. 

As it stands previously, the iPhone just automatically defaulted to Apple's own Safari web browser. To swap the default to another option like Firefox, Google Chrome, or Opera, you'd have to navigate to Settings to change it. Now, due to the DMA mandate, Apple will now prompt EU users to make a choice.

Developers will also have a choice, too. Previously, developers were only allowed to use Apple's WebKit for browser apps and in-app browser experiences. Now, they can use alternative web browser engines as well.

Delete the iPhone's Safari app

Speaking of Safari, have you ever tried to delete the app from your iOS device? You can't.

Well, that will soon change – if you're an EU user.

Apple announced in its DMA compliance report that it plans to let users completely delete the Safari app from their iPhone. Users were previously prohibited to do so because Apple's web browser is so deeply integrated with iOS. Apple is preparing to make that change now though.

Interoperability: First up, Payments

Using Apple Pay is easy. Users can just scan their iPhone at a register and pay for their item with any number of payment options in their Apple Wallet.

Now, Apple will let developers of third-party payment apps access the NFC chip inside the iPhone, which makes it all possible. Soon, users will be able to use their iPhone to pay for products and services through a third-party payment app as well.

Apple says it will also consider other interoperability requests from developers on a case-by-case basis.

Easier transfers to Android and other mobile operating systems

Looking to leave your iPhone behind for an alternative, but feel stuck due to all the data you have tied up with Apple?

The DMA has pushed Apple to change this as well.

According to Apple, it's working on giving providers of mobile operating systems like Android "more user-friendly solutions" for users seeking to transfer data from the iPhone to a non-Apple device.

Most of these DMA-influenced Apple changes are on the way later this year or early next year, according to Apple. The latest scheduled feature – easier transferring process from an iPhone – is currently scheduled for fall 2025.
