Error: Could not load NIB in bundle: 'NSBundle

If your app builds, but then crashes when you try to load a particular view, chances are you've forgotten a simple step.

This happens when you are using .xib files along with code. For me, I'm using a programatic table view, with .xibs.

This the full error message:

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Could not load NIB in bundle: 'NSBundle <long path name/AppName.app> (loaded)' with name '<Name of the nib>''

Some things to check:

• You have registered the nib: tableView.register(UINib(nibName: T.dequeueIdentifier, bundle: nil), forCellReuseIdentifier: T.dequeueIdentifier)
• The fileName.xib is exactly the same as the name you used to register. This is where I tripped up. I was using nibName: ListStandardIconCell, but my file name was ListStandardIcon.xib. When I changed it to ListStandardIconCell.xib, the crash went away.
• Have a .swift file that is associated to the nib, so that you can drag in the outlets

import UIKit

// MARK: - ListStandardIconCell

final class ListStandardIconCell: UITableViewCell {

    // MARK: Outlets

    @IBOutlet private weak var titleLabel: UILabel!
    @IBOutlet private weak var iconImageView: UIImageView!
}

• The custom class is set to the associated .swift for that nib (see image below)
