Error: (@lvalue Double, @lvalue Double)' is not convertible to 'Double'

Hi guys, I need help with this excercise, because I get an error message at the end and I can't figure out what is the problem. Something Double isn't convertabele to Double, what? When I solve it in xcode it gives me all the numbers no broblem while displaying the same error, I haven't seen this before.

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) -> Double { 
 width =  width + points
  height =  height + points
  return (width,height)
  }
}

Never mind, I'm an idiot, I had it return 2 Doubles when only 1 was expected.
