Swift - Closure cannot have keyword arguments Error In Xcode 7.3

Question

I have updated to Xcode 7.3 and some of my Libraries including Toast and CNPopupButton are giving me this error: Closure cannot have keyword arguments

And then it asks me to delete the argument Type Name.

What could be the problem here?

Answer 1

Since Swift 2.2 (which comes with Xcode 7.3) a declaration like:

button.selectionHandler = { (CNPPopupButton button) -> Void in

should be

button.selectionHandler = { (button : CNPPopupButton) -> Void in

Which indeed feels more Swift-ish. If you don't want to pin down the type, you can also use the short-hand syntax:

button.selectionHandler = { button in
