Why does it keep saying there is an error with the "=" signs?

Please help.

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 + width
  height = points + height
  }
  }
}

Looks like a problem with your syntax: 

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
    }
}
