Nib load failure when presenting its view controller

Question

I have this function in a class that inherits from NSObject:

open func showCustomDialogInView(vc: UIViewController) {
    let bundle = Bundle(for: CustomDialogViewController.self)
    let customDialog = CustomDialogViewController(nibName: "CustomDialogViewController", bundle: bundle)
    customDialog.delegate = vc
    customDialog.modalPresentationStyle = UIModalPresentationStyle.overCurrentContext
    vc.present(customDialog, animated: true, completion: nil)
}

I had this working in one of my iOS projects before updating to Xcode 8 and Swift 3 language, but now when I run the app I get a crash when vc.present(customDialog, animated: true, completion: nil) line is reached. I get this message in log console:

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Could not load NIB in bundle: 'NSBundle /MyApp.app> (loaded)' with name 'CustomDialogViewController''

I don't understand what it is happening, since let customDialog = CustomDialogViewController(nibName: "CustomDialogViewController", bundle: bundle) line doesn't crash and it seems that I get a CustomDialogViewController object.

Does somebody could help me with this issue? Thanks

You have already indicated "Xcode 8 & swift 3" in the tags, no need to have it in the title as well. — Léo Natan, Oct 22 '16 at 17:47

This error can occur when you rename files outside of XCode. To solve it you can just remove the files from your project (Right Click - Delete and "Remove Reference").

Then after you can re-import the files in your project and everything will be OK.

It looks like in this case this error was because for some reason the xib file was missing the appropriate target membership.

Thanks for your answers
