The view item in the vault crash is due to conflicting layout constraints on the view. Here's an extract from the console log: Apr 7 07:57:55 iPhone-5s bungie_mobile[357] <Warning>: 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. ( "<MASLayoutConstraint:0x158bf3810 BNGActivityIndicator:0x15932b7a0.bottom <= CommonLoadingView:0x1591c60a0.bottom - 7>", "<MASLayoutConstraint:0x1591eeca0 BNGActivityIndicator:0x15932b7a0.centerY == CommonLoadingView:0x1591c60a0.centerY>", "<MASLayoutConstraint:0x15931f350 CommonLoadingView:0x1591c60a0.height == 0>" ) Will attempt to recover by breaking constraint <MASLayoutConstraint:0x158bf3810 BNGActivityIndicator:0x15932b7a0.bottom <= CommonLoadingView:0x1591c60a0.bottom - 7> Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger. The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful.
