개요
iOS14.2 이상의 iPad에서 UITextField를 포커스하면 다음 경고가 기록됩니다. iOS 14.1 이전의 iPad에서는 발생하지 않으므로 OS 버그 일 것입니다.

Probably at least one of the constraints in the following list is one you don't want.
Try this:
(1) look at each constraint and try to figure out which you don't expect;
(2) find the code that added the unwanted constraint or constraints and fix it.
(Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints)

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKitCore/UIView.h> may also be helpful.

검증 앱
아래와 같이 적당히 UITextField를 배치한 앱을 만듭니다. ViewController와 같은 프로그램은 기본값으로 유지됩니다. 물론 이 시점에서는 LayoutContraints 경고가 나오지 않습니다.
iOS 14.2의 iPad 시뮬레이터에서 실행하고 UITextField를 포커스하면 로그가 출력됩니다.
당연히 NavigationController는 사용하고 있지 않습니다만, 문제의 제약안에 _UIButtonBarButton 가 있는 것이 수수께끼군요.
