Setting up Google Tag Manager in Swift involves the following steps:

1. Sign up for a Google Tag Manager account and create a new container.
2. Generate a container snippet by going to your container's "Install Google Tag Manager" page.
3. In your Xcode project, navigate to the AppDelegate.swift file.
4. Import the GoogleTagManager library by adding the following line at the top of the AppDelegate.swift file: import GoogleTagManager
5. Inside the application(_:didFinishLaunchingWithOptions:) method, add the following code to initialize the Google Tag Manager: TAGManager.instance().logger.setLogLevel(kTAGLoggerLogLevelVerbose) TAGManager.instance().logger.setDebugDispatchURL(true) TAGManager.instance().logger.setDebugDispatchData(true) TAGContainerOpener.openContainer(withId: "GTM-XXXXXX", // Replace "GTM-XXXXXX" with your container ID tagManager: TAGManager.instance(), openType: kTAGOpenTypePreferFresh, timeout: nil, notifier: self)
6. Implement the TAGContainerOpenerNotifier protocol in the AppDelegate class to receive container load notifications. class AppDelegate: UIResponder, UIApplicationDelegate, TAGContainerOpenerNotifier { // ... func containerAvailable(_ container: TAGContainer!) { container.refresh() } }
7. In your desired view controller, import GoogleTagManager library by adding the following line at the top: import GoogleTagManager
8. Add the following code to obtain the container reference and push any desired data layer changes: let container = TAGManager.instance().container(withId: "GTM-XXXXXX") // Replace "GTM-XXXXXX" with your container ID container?.push(["event": "xyz", "key1": "value1"]) // Example data layer update
9. Build and run your app to test the integration of Google Tag Manager in Swift.

Note: The above steps provide a basic setup for Google Tag Manager. Further customization can be done using the GTM SDK documentation and API references according to your specific requirements.
