问题 In Xcode 6 beta 2 it worked fine, but in beta 4 it doesn't work anymore. Does anyone know what's behind this mystery? let circle = SKShapeNode(circleOfRadius: 125); circle.strokeColor = UIColor(red: 255, green: 255, blue: 255, alpha: 1.0); circle.lineWidth = 4 self.addChild(circle); In beta 4 nothing can be seen.

问题 I'm new to programming for iOS and OSX, and decided to start with Swift and use the iOS8 API's for a test app and attempt some programming techniques I use in other environments. However, I'm encountering a strange situation which I hope someone could identify and help me with. This involves difficulties subclassing UIAlertController.
