better way to set alpha for a view after a few seconds in apple watch / watchkit in swift

Question

I am trying to set alpha with animation to image view in swift for apple watch application.

to do that i have tried code below

UIView.animateWithDuration(1.5, animations: {
        self.splashscreenImage.alpha = 1.0
        return
   })

but its iving error as

  'WKInterfaceImage' does not have a member named 'alpha'

so i implemented code below in willActivate function

var timer = NSTimer.scheduledTimerWithTimeInterval(5, target: self, selector: Selector("splashscreenAlpha"), userInfo: nil, repeats: false)

and

func splashscreenAlpha() {
   self.splashscreenImage.setAlpha(0.0)
}

but in this scenario, view is like invisible, like image view has a black background. But i would like it to gone with animation. How can i do that?

Answer 1

You should try using

UIView.animateWithDuration(1.5, animations: { self.splashscreenImage.setAlpha(1.0) return })

to make alpha animation.
