[SOLVED] Nib load failure when presenting its view controller

Nib load failure when presenting its view controller

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

Solution

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
