Unable to stop timer through another viewcontroller, Swift - swift

Question

I developing a timer app for an apple watch.
I have two different Views at the moment. One with the actual timer (TimerController) and another with a pause-button (SwipeController).
I'm trying to stop/start the timer in the TimerController with the action from the button in the SwipeController.
Problem is that the timer stops, but the timer will not start again after hitting the button the second time.
If I press the button one time, the timer stops. If i press it again two times the timer will start again but will not stop when hitting the button again.
Any ideas of what the problem could be?

it looks like you aren't ever actually checking for you isPaused boolean to be true or false in your if statement when checking if your timer is paused.
if isPaused { <-----------
myTimer = Timer.scheduledTimer(timeInterval: 1,
target:self, selector: #selector(timerDone), userInfo: nil,
repeats: true)
self.isPaused = false
print("timer paused: resumming1")
