Xcode 8.0 copy main.storyboard

I tried to upgrade the swift 2.2 to swift 3.0.

I failed. Now I started a new 3.0 project and copied my files into the new project. How can I get the new project to work with a copy of the main.storyboard I copied from another project?

When I run the project, push the button.

Any idea to change the links to work?

You need to do one of these things:

  • change the signature of your action handler so the external name of the parameter is _, e.g,

    func ButtonAction(_ sender:Any)

  • or delete your action in the storyboard and create it afresh

The reason is that Swift 3 changes all the ObjectiveC names of your action handlers so now none of your button actions work.
