Sample App

This simple app shows a welcome message. You can archive and upload this app to TestFlight to share with testers.

iOS Swift

// This is a conceptual example since TestFlight setup is done outside code.
// But here is a simple SwiftUI app you can upload for TestFlight testing.
import SwiftUI

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

struct ContentView: View {
  var body: some View {
    Text("Welcome to TestFlight Beta!")
      .padding()
      .font(.title)
  }
}

Important Notes

TestFlight requires your app to pass basic App Store review before external testing.

Internal testers can start testing immediately after upload.

External testers need to accept invitation and wait for review approval.

Summary

TestFlight lets you share your app with testers before public release.

You upload your app archive to App Store Connect and invite testers.

Testers use the TestFlight app to install and test your app easily.
