Vibration for runway layer

Animated gif

In iOS9 Apple finally made the CASpringAnimation class public, we can simplly create an attractive spring animation effecting CALayer. But our indicator view must be compatible with iOS8+. To archive the subtle effects for runway layer, we should dig out little physics knowledge, that is the Vibration.

Pls check reference bellow:

Requirements

  • Swift 3.0+
  • iOS 8.0+
  • Xcode 8.0+
