Anexample app is included demonstrating Cribble's functionality.
Simply add the following lines into your app delegate:
import Cribble override func motionBegan(motion: UIEventSubtype, withEvent event: UIEvent?) { guard motion == .MotionShake else { return } Cribble.shared.hidden = !Cribble.shared.hidden }
Shake a device and explore ui's roughness.
 You may want to use your own parameters for the grid. In that case simply use CribbleOptions : 
let options = CribbleOptions(horizontalStep: 10, verticalStep: 10, opacity: 0.7, color: UIColor.redColor()) Cribble.shared.options = options
