[LayoutConstraints] Unable to simultaneously satisfy constraints. #43

Closed codepgq closed 5 years ago

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.

Will attempt to recover by breaking constraint <SnapKit.LayoutConstraint:0x1c42af480@DeviceNewListController.swift#60 UICollectionView:0x104925a00.right == UIView:0x104341350.right - 10.0>

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.
