CoreDataTest[2010:60b] 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) ( "<NSLayoutConstraint:0x17ee8ba0 V:[UILabel:0x17efb790(20)]>", "<NSLayoutConstraint:0x17edd410 V:|-(2)-[UILabel:0x17efb790] (Names: '|':UITableViewCellContentView:0x17eeb260 )>", "<NSLayoutConstraint:0x17edf100 V:[UILabel:0x17ee4a70]-(0)-| (Names: '|':UITableViewCellContentView:0x17eeb260 )>", "<NSLayoutConstraint:0x17edec60 V:[UILabel:0x17efb790]-(2)-[UILabel:0x17ee4a70]>", "<NSAutoresizingMaskLayoutConstraint:0x17f33410 h=--& v=--& V:[UITableViewCellContentView:0x17eeb260(0)]>" ) Will attempt to recover by breaking constraint <NSLayoutConstraint:0x17ee8ba0 V:[UILabel:0x17efb790(20)]> Break on objc_exception_throw to catch this in the debugger. The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful.
