  init(cornerRadius:Double){
    self.cornerRadius = cornerRadius
    super.init = (width:width, height: height)
  }  
}

Hello:

The problem is how you are calling your super.init. You don't have to use the assignment operator =.

class RoundButton: Button {
    var cornerRadius: Double = 5.0

    init(width:Double,height:Double,cornerRadius:Double){
        self.cornerRadius = cornerRadius
        super.init(width: width, height: height) // Fix here by deleting = 
    }  
}

Good luck
