UITextView convenience initializer does not call designated initializer since iOS 16. The UITextView.init(usingTextLayoutManager:) that is a "convenience" initializer for the UITextView, does not call UITextView.init(frame:textContainer:) that is a designated initializer. This behavior, when the class interface traslated to Swift interface, breaks the Swift rules of object initialization. I believe that is also incorrect in Objective-C, although the compiler doesn't check that.

code snippet to reproduce:

final class CustomTextView: UITextView {

    override init(frame: CGRect, textContainer: NSTextContainer?) {
        // DESIGNATED INITIALIZER IS NEVER CALLED
        super.init(frame: frame, textContainer: textContainer)
    }

    required init?(coder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
}


let textView = CustomTextView(usingTextLayoutManager: true)
