Xcode 8.1 issues and unwinding

Question

I can’t figure it out to work with the latest Xcode 8.1GM. I'm just wondering if I'm the only one or someone else is experiencing the same thing. I installed view controllers, as before, it worked in Xcode8.0, but now I’m out of luck. I tried to clean and so on, but nothing helps. I would like someone else to check it out and then I introduced the radar ...

view controllerthat first created the instance view controllerhas the following code:

@IBAction func unwindToSettingsTableViewController(_ segue: UIStoryboardSegue) {
    print("unwind")
}

I also tried without underscore, but that didn't help. When you configure this, you must be able to ctrldrag from the owner of the file to exit and get off: So either I'm doing it completely wrong (I don’t think it worked fine before), or there is an error inXcode 8.1

I tried to do the same in a new project, and then it worked correctly. So I think something is wrong with my project or storyboard file.

Update

Since storyboards contain fairly small scenes, I simply deleted them and recreated them again using the same classes for view controllers and so on. And now it works. So, having exactly the same code, but a fresh storyboard, it seems to me that this is some kind of error.

I can create a new project and not create problems with creating an interchange, but even creating a new storyboard in my current project using only the NavigationController and two ViewControllers, rewinding does not appear on the exit button.

This is a very annoying mistake because it led to the cessation of my project.
