Reloaded 1 of 1940 libraries in 334ms. [LayoutConstraints] Unable to simultaneously satisfy constraints. 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) ( "<NSAutoresizingMaskLayoutConstraint:0x283b1d5e0 h=-&- v=--& UINavigationBar:0x10476f540.minY == 0 (active, names: '|':UILayoutContainerView:0x1047df690 )>", "<NSAutoresizingMaskLayoutConstraint:0x283b1fbb0 h=-&- v=--& UINavigationBar:0x10476f540.height == 44 (active)>", "<NSLayoutConstraint:0x283b19d10 V:[UINavigationBar:0x10476f540]-(0)-[UIFocusContainerGuide:0x282775ef0'UINavigationControllerContentFocusContainerGuide'] (active)>", "<NSLayoutConstraint:0x283b1b890 UIFocusContainerGuide:0x282775ef0'UINavigationControllerContentFocusContainerGuide'.bottom == UILayoutContainerView:0x1047df690.bottom (active)>", "<NSLayoutConstraint:0x283b1b610 V:|-(0)-[UILayoutContainerView:0x1047df690] (active, names: QLPreviewControllerView:0x11d6513f0, '|':QLPreviewControllerView:0x11d6513f0 )>", "<NSLayoutConstraint:0x283b1a440 V:[UILayoutContainerView:0x1047df690]-(0)-| (active, names: QLPreviewControllerView:0x11d6513f0, '|':QLPreviewControllerView:0x11d6513f0 )>", "<NSLayoutConstraint:0x283b1f2a0 'UIView-Encapsulated-Layout-Height' QLPreviewControllerView.height == 0 (active, names: QLPreviewControllerView:0x11d6513f0 )>" ) Will attempt to recover by breaking constraint
