What does this error mean?

Why am I getting this error?

swift_lint.swift:24:1: error: expected declaration

^
Button.swift 
class Button {
  var width: Double
  var height: Double

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

  func incrementBy(points: Double){
    width += points
    height += points
  }
}

class RoundButton: Button {
  var cornerRadius: Double = 5.0

  override func incrementBy(_ points: Double = 7.0){
    return super.incrementBy(points)
}

Looks like you're missing a closing curly brace on your RoundedButton class declaration.

Aren't error messages fun? :)

Yes, I love error messages (not really)! Thanks, that makes sense, it's usually the small thing that get me.
