timerButton.setTitle("Start", forState: .Normal)
Thank you Steve Hunter who posted this response on another post a few hours back

14,452 PointsMatthias Seeber .Normal refers to the state in which the button is to set the title, so in this instance when the button is normal (i.e nothing going on) the title is "Start".
You can choose to set titles for different states, so .Highlighted for example. If you do not specify any other state the button will always use the .Normal state title as its default title no matter what, if its highlighted, selected or what ever.
Take a look at UIButton class reference setTitle(_:forState:) in apple docs: https://developer.apple.com/library/prerelease/ios/documentation/UIKit/Reference/UIButton_Class/index.html#//apple_ref/occ/instm/UIButton/setTitle:forState:
and UIControlState at: https://developer.apple.com/library/prerelease/ios/documentation/UIKit/Reference/UIControl_Class/index.html#//apple_ref/c/tdef/UIControlState
Just taking a brief look will give you an idea of what the state may be used for in another case (this is funny because the ControlStates are stored in a Enum.... case..... bad joke but hey ho).
Hope this helps Thanks Dom
