Timers in SwiftUI • Law

I learned how to use timers in SwiftUI. For example, I want to display a launcher view in 3 seconds and then proceed to the next View().

@State private var timerCount = 0
@State private var exitFromLauncher = false
private let timer = Timer.publish(every: 1, on: .main, in: .common).autoconnect()

In our view:

var body: some View {
  if exitFromLauncher {
    // go to HomeView()
  } else {
    // Launcher UI
    ZStack {
    }
    .onReceive(timer) { input in
      if timerCount < 3 {
                            timerCount += 1
                        }
                        if timerCount == 3 {
          exitFromLauncher = true
                            timer.upstream.connect().cancel()
                        }
                }
       }
}
