Swift subclass UIView

I usually do something like this, its a bit verbose.

class MyView: UIView {
    override init(frame: CGRect) {
        super.init(frame: frame)
        addBehavior()
    }

    convenience init() {
        self.init(frame: CGRect.zero)
    }

    required init(coder aDecoder: NSCoder) {
        fatalError("This class does not support NSCoding")
    }

    func addBehavior() {
        print("Add all the behavior here")
    }
}



let u = MyView(frame: CGRect.zero)
let v = MyView()

(Edit: I've edited my answer so that the relation between the initializers is more clear)

This is more simple.

override init (frame : CGRect) {
    super.init(frame : frame)
    // Do what you want.
}

required init?(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)
}
