Window is nil when push or present to another view controller #7

Hi Kaandedeoglu, I used this lib to show circular progress view on a view controller and after finishing animation, I want to push or present to another view controller, app is crashed because new window is nil. This bug is here: public override func didMoveToWindow() { progressLayer.contentsScale = window!.screen.scale } It should be: public override func didMoveToWindow() { if let window = window { progressLayer.contentsScale = window.screen.scale } } Best regards !
