[swift-users] #selector with Swift 3?

[Nathan Day]

I had a bit of problem getting #selector working with swift 3 I eventual got it to work with your second to last line I think, I've had a couple of problems with errors that I can't fix, type casting mainly, I have often found fixing other errors, even if they come after will make the initial error go away, I have passed it of as beta problems, I still have finished so I don't know if all my problems can be fixed like this.
