I was looking at the Swift code in the Stickies app and I noticed this error in mute action:
Cannot invoke 'animationWithDuration' with an argument of list type '(Double, delay: Double, options: NSArray, animations: () -> Void, completion: nil)'
@IBAction func mute() {
UIView.animateWithDuration(1.0, delay: 0.0, options: [], animations: <=== error
{ () -> Void in
self.alpha = 0.25
}, completion: nil)
}
Pasan Premaratne , or Gabe Nadel , can you take a look?

{ () -> Void in
self.alpha = 0.25
}, completion: nil)
You are using an array for options when you need to use UIViewAnimationOptions

Treehouse Moderator 37,862 PointsI downloaded the project files from the Stickies app in this workshop, in Objective-C the options are set to '0', so I guess that means there are no options. So how would you do that in Swift? is that what UIViewAnimationOptions.CurveLinear does?
Brayden Kness
12,492 PointsYes essentially UIViewAnimationOptions.CurveLinear is a fancy way of saying that that there are no options

Treehouse Moderator 37,862 PointsOkay, that makes sense.
