Potential memory leak on Timer.scheduledTimer

[skywalkerlw]

Since there's no invalidation operation on Timer.scheduledTimer, I'm wondering whether there could be a memory leak problem.

Timer.scheduledTimer(withTimeInterval: animationTime, repeats: true) { (mainTimer) in
                self.animateSpinner()
            }

Hi @skywalkerlw!

thanks for reporting this. It's likely that this produces a memory leak, will dig into it :)
