@IBDesignable crashing agent

by

Xcode’s Interface Builder requires that you implement both or neither initializers for @IBDesignable classes to render properly in IB.

If you implement required init(coder aDecoder: NSCoder) you’ll need to override init(frame: CGRect) as well, otherwise “the agent will crash” as seen in the errors thrown by Xcode.

To do so add the following code to your class:

override init(frame: CGRect) {
    super.init(frame: frame)
}
