Setting Up Your Application in SwiftUI

For Scene-based SwiftUI applications, I recommend adding the initialization to your @main App struct! Open YourAppNameApp.swift and look for code that looks like this:

import SwiftUI

@main
struct Example_AppApp: App {
    var body: some Scene {
        WindowGroup {
            ContentView()
        }
    }
}

This is the entry point to your app. Now let's add the initialization here.

Import the TelemetryClient Package by adding import TelemetryClient. Then add an init() method to your App struct that creates a TelemetryManagerConfiguration instance and hands it to the TelemetryManager, using the Unique Identifier of your app that you copied into your clipboard earlier. If you don't have that any more, you can get it at any time from the TelemetryDeck Viewer app.

Your code should now look like this:

import SwiftUI
import TelemetryClient

@main
struct Example_AppApp: App {
    var body: some Scene {
        WindowGroup {
            ContentView()
        }
    }

    init() {
        let configuration = TelemetryManagerConfiguration(
            appID: "YOUR-APP-UNIQUE-IDENTIFIER")
        TelemetryManager.initialize(with: configuration)
    }
}

If you already have an init() method, add this to its end.

You did it!

You've finished setting up your application and are now ready to send some signals.
