UIView initializer swift Xcode 6 beta 5

Question

xcode 6 beta 5

Error:

Class 'ClassName' does not implement its superclass's required members

on

    class ClassName:UIView

also showing an error

on

        init(frame: CGRect) {
            super.init(frame: frame)
            // Initialization code
            self.backgroundColor = UIColor.clearColor()
        }

Overriding declaration required an 'ovveride' keyword

I placed override before init, ovveride error was remove but superclass error was not

thanks in advance

in Xcode6 beta5 the -init(coder:) has became a required method to be overridden:

 class ClassName: UIView {

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

    //

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

}

Why we use required init(coder aDecoder: NSCoder!) { super.init(coder: aDecoder) // ... } and how? – Muhammad Raza Aug 06 '14 at 13:03

and why other init are to be override? – Muhammad Raza Aug 06 '14 at 13:05

if you want to init your view via unarchiving an existing object (after you archived it, of course), you can restore the view's previous state from the archive here. – holex Aug 06 '14 at 13:06

you also need to flag the standard init method as overridden in your class. – holex Aug 06 '14 at 13:07

I also think this answer needs further explanation. Please add it to the answer and not just in comments. – Michael Yagudaev Oct 27 '14 at 07:45
