UIButton in Swift is not registering touches

Question

I\'m trying to create a UIButton using Swift. It compiles fine and I can see my button in the simulator, but when I click it, nothing happens. This is the code I am using:

Old question, but thought I'd give some help to other looking for this issue. First off, I'm not entire sure this is correct so please correct me if I'm wrong.

But if you set the selector wrongly the application would crash when you press the button since it's subscribed to a selector which doesn't exist. Which means that your selector is working. My guess is that something else is blocking the touch event, assuming UIButton.enabled = true and UIButton.userInteractionEnabled = true. Usually you could check this by long pressing the button and see if it hits. If it does then you have a UIGestureRecognizer added somewhere which takes up the hits first. Could also be the UIScrollView which is delaying the touch input (there's a checkbox for this in the Inspector).

Hope this helps someone, and hope it's accurate.
