Why do I see NSAutoresizingMaskLayoutConstraint when all user interface elements are setTranslatesAutoresizingMaskIntoConstraints = NO

I am trying to debug the user interface layout, and all the elements that I added in the code are marked as [self.element setTranslatesAutoresizingMaskIntoConstraints: NO]; The only thing set in the XIB file is the background color in the view (one of many types in tabbed view.

When I look at NSLog, I see the following:

*<UIWindow:0xc352370> - AMBIGUOUS LAYOUT | *<UILayoutContainerView:0xc3651b0> | | *<UINavigationTransitionView:0xc355b40> | | | *<UIViewControllerWrapperView:0xbd3e250> | | | | *<UILayoutContainerView:0xbd3da60> | | | | | *<UITransitionView:0xbd46ed0> | | | | | | *<UIViewControllerWrapperView:0xc09a450> | | | | | | | *<UIView:0xbd51f40> | | | | | | | | *<_UILayoutGuide:0xbd51fa0> - AMBIGUOUS LAYOUT | | | | | | | | *<_UILayoutGuide:0xbd50a10> - AMBIGUOUS LAYOUT | | | | | | | | *<UIButton:0xc064170> - AMBIGUOUS LAYOUT | | | | | | | | | *<UIButtonLabel:0xc09d640> | | | | | | | | *<UILabel:0xc073990> - AMBIGUOUS LAYOUT | | | | | | | | *<UIButton:0xc0576a0> - AMBIGUOUS LAYOUT | | | | | | | | | *<UIButtonLabel:0xc095290> | | | | | | | | *<UIButton:0xc096640> - AMBIGUOUS LAYOUT | | | | | | | | | <UIButtonLabel:0xc096820> | | | | | | | | *<UIButton:0xc098b70> - AMBIGUOUS LAYOUT | | | | | | | | | <UIButtonLabel:0xc098cb0> | | | | | | | | *<UIButton:0xc09a4c0> - AMBIGUOUS LAYOUT | | | | | | | | | <UIButtonLabel:0xc09a6d0> | | | | | | | | *<UILabel:0xc09c9d0> - AMBIGUOUS LAYOUT | | | | | | | | *<UILabel:0xc09cc60> - AMBIGUOUS LAYOUT | | | | | | | | *<UIButton:0xc09ce00> - AMBIGUOUS LAYOUT | | | | | | | | | <UIButtonLabel:0xc09d010> | | | | | | | | *<UILabel:0xc0a25f0> - AMBIGUOUS LAYOUT | | | | | | | | *<UIButton:0xc0a2800> - AMBIGUOUS LAYOUT | | | | | | | | | <UIButtonLabel:0xc0a2a10> | | | | | | | | *<UILabel:0xc0a5720> - AMBIGUOUS LAYOUT | | | | | <UITabBar:0xc356c00> | | | | | | <_UITabBarBackgroundView:0xbe28cc0> | | | | | | | <_UIBackdropView:0xbe29100> | | | | | | | | <_UIBackdropEffectView:0xbe296e0> | | | | | | | | <UIView:0xbe29780> | | | | | | <UITabBarButton:0xbd42000> | | | | | | | <UITabBarSwappableImageView:0xbd41050> | | | | | | | <UITabBarButtonLabel:0xbd43320> | | | | | | <UITabBarButton:0xbd462e0> | | | | | | | <UITabBarSwappableImageView:0xbd45d60> | | | | | | | <UITabBarButtonLabel:0xbd45c70> | | | | | | <UITabBarButton:0xbd47770> | | | | | | | <UITabBarSwappableImageView:0xbd48a90> | | | | | | | <UITabBarButtonLabel:0xbd486c0> | | | | | | <UITabBarButton:0xbd4c0c0> | | | | | | | <UITabBarSwappableImageView:0xbd4c220> | | | | | | | <UITabBarButtonLabel:0xbd4aea0> | | | | | | <UIImageView:0xbe29ed0> | | <UINavigationBar:0xc06c4a0> | | | <_UINavigationBarBackground:0xc05e720> | | | | <_UIBackdropView:0xc357d70> | | | | | <_UIBackdropEffectView:0xc3639a0> | | | | | <UIView:0xc355470> | | | | <UIImageView:0xc071980> | | | <UINavigationItemView:0xc074c80> | | | | <UILabel:0xc083730> | | | <_UINavigationBarBackIndicatorView:0xc36edb0> po [ (lldb) po [0xbd51fa0 constraintsAffectingLayoutForAxis:0] <__NSArrayM 0xbd39190>( ) (lldb) po [0xbd50a10 constraintsAffectingLayoutForAxis:0] <__NSArrayM 0x1121f8f0>( ) (lldb) po [0xc064170 constraintsAffectingLayoutForAxis:0] <__NSArrayM 0xc0a14e0>( <NSLayoutConstraint:0xc093aa0 H:|-(NSSpace(20))-[UIButton:0xc064170] (Names: '|':UIView:0xbd51f40 )>, <NSLayoutConstraint:0xc093b30 UIButton:0xc064170.width == UIButton:0xc0576a0.width>, <NSLayoutConstraint:0xc093be0 H:[UIButton:0xc064170]-(20)-[UILabel:0xc073990]>, <NSLayoutConstraint:0xc093c10 UILabel:0xc073990.width == UIButton:0xc0576a0.width>, <NSLayoutConstraint:0xc096530 H:[UILabel:0xc073990]-(20)-[UIButton:0xc0576a0]>, <NSLayoutConstraint:0xc096590 H:[UIButton:0xc0576a0]-(NSSpace(20))-| (Names: '|':UIView:0xbd51f40 )>, <NSAutoresizingMaskLayoutConstraint:0xc0af130 h=--& v=--& H:[UIView:0xbd51f40(768)]> ) (lldb) po [0xc09a4c0 constraintsAffectingLayoutForAxis:0] <__NSArrayM 0xc36a0a0>( <NSLayoutConstraint:0xc09c9a0 H:|-(<=0)-[UIButton:0xc09a4c0] (Names: '|':UIView:0xbd51f40 )>, <NSContentSizeLayoutConstraint:0xc0ad530 H:[UIButton:0xc09a4c0(110)] Hug:250 CompressionResistance:750>

As you can see from the po commands, I get NSAutoresizingMasktLayoutContraints. I thought this should not be?

How can I guarantee that I will not get this?

Good. I found out that the restrictions did not correspond to the corresponding relations with each other. I updated the code, and now I can get pure restrictions for all aspects except the main UIWindow, which, I'm sure, is only due to a problem with the UILayoutGuide, which is ambiguous -

 *<UIWindow:0xcc6d7f0> - AMBIGUOUS LAYOUT | *<UILayoutContainerView:0xbd34720> | | *<UINavigationTransitionView:0xbd4b140> | | | *<UIViewControllerWrapperView:0xcc48400> | | | | *<UILayoutContainerView:0xbd5ad40> | | | | | *<UITransitionView:0xbd635c0> | | | | | | *<UIViewControllerWrapperView:0xcca68b0> | | | | | | | *<UIView:0xcc9ddd0> | | | | | | | | *<_UILayoutGuide:0xcc9de30> - AMBIGUOUS LAYOUT | | | | | | | | *<_UILayoutGuide:0xcc9e090> - AMBIGUOUS LAYOUT | | | | | | | | *<UIButton:0xcc9d910> | | | | | | | | | <UIImageView:0xcc9dd20> | | | | | | | | *<UILabel:0xcc9e860> | | | | | | | | *<UIButton:0xcc9ebb0> | | | | | | | | | <UIImageView:0xcc9eda0> | | | | | | | | *<UIButton:0xcc9f020> | | | | | | | | | <UIButtonLabel:0xcc9f470> | | | | | | | | *<UIButton:0xcca0620> | | | | | | | | | <UIButtonLabel:0xcca0830> | | | | | | | | *<UIButton:0xcca15d0> | | | | | | | | | *<UIButtonLabel:0xcca17e0> | | | | | | | | *<UILabel:0xcca2580> | | | | | | | | *<UILabel:0xcca2710> | | | | | | | | *<UIButton:0xcca28d0> | | | | | | | | | *<UIButtonLabel:0xcca2ae0> | | | | | | | | *<UILabel:0xcca3880> | | | | | | | | *<UILabel:0xcca3bd0> | | | | | | | | *<UIButton:0xcca3e30> | | | | | | | | | *<UIButtonLabel:0xcca4040> | | | | | | | | *<UILabel:0xcca4de0> | | | | | | | | *<UILabel:0xcca5000> | | | | | <UITabBar:0xcc69e40> | | | | | | <_UITabBarBackgroundView:0xcccad10> | | | | | | | <_UIBackdropView:0xcccb150> | | | | | | | | <_UIBackdropEffectView:0xcccb730> | | | | | | | | <UIView:0xcccb7d0> | | | | | | <UITabBarButton:0xcc96bf0> | | | | | | | <UITabBarSwappableImageView:0xcc8d330> | | | | | | | <UITabBarButtonLabel:0xcc8d270> | | | | | | <UITabBarButton:0xcc98830> | | | | | | | <UITabBarSwappableImageView:0xcc81840> | | | | | | | <UITabBarButtonLabel:0xcc983a0> | | | | | | <UITabBarButton:0xcc9a050> | | | | | | | <UITabBarSwappableImageView:0xcc8e3e0> | | | | | | | <UITabBarButtonLabel:0xcc9a130> | | | | | | <UITabBarButton:0xcc9a560> | | | | | | | <UITabBarSwappableImageView:0xcc9b140> | | | | | | | <UITabBarButtonLabel:0xcc9aa20> | | | | | | <UIImageView:0xcccbf20> | | <UINavigationBar:0xbd27340> | | | <_UINavigationBarBackground:0xbd2fc60> | | | | <_UIBackdropView:0xbd43740> | | | | | <_UIBackdropEffectView:0xbd2c200> | | | | | <UIView:0xbd46100> | | | | <UIImageView:0xbd2ffd0> | | | <UINavigationItemView:0xbd1e270> | | | | <UILabel:0xbd283c0> | | | <_UINavigationBarBackIndicatorView:0xbd566e0>

UILayoutGuide is not installed anywhere in my code, so I'm not quite sure what to do with it.
