SwiftUI: How do you restart a timer after cancelling it?

Answer 1

if you have a countdown timer, you define it something like this:

let timer = Timer.publish(every: 1, on: .main, in: .common).autoconnect()

...and use it on a Text field for e.g.:

    Text("Punkte: \(Punkte.formatnumber())")
        .onReceive(timer) { input in
                            if time < 1 { gameOver() } else { self.time -= TimerToggle ? 1 : 0  }
                    }

so you only have to set the Toggle in the action of the button:

Button(action: { TimerToggle.toggle() }, label: {
                    Text("Pause")
                })

Much simpler and works in SwiftUI 5.2
