Swift subclass UIView

Question

I want to subclass UIView and show a login like view. I've created this in Objective-C, but now I want to port it to Swift. I do not use storyboards, so I create all my UI in code.

But the first problem is that I must implement initWithCoder. I gave it a default implementation since It won't be called. Now when I run the program it crashes, because I've to implement initWithFrame as well. Now I got this:

override init() {     super.init()     println("Default init") }  override init(frame: CGRect) {     super.init(frame: frame)     println("Frame init") }  required init(coder aDecoder: NSCoder) {     super.init(coder: aDecoder)     println("Coder init") } 

My question is where should I create my textfield etc... and if I never implement frame and coder how can I "hide" this?

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)
