Area: UIKit Summary: Setting constraints relative to layout margins guide in designated initializer doesn't work reliably. If you set the constraints of a view via code, the layout margins guide is not set properly if you initialize the view with .zero Steps to Reproduce: occurs if view is created via code and layout margins are set in viewDidMoveToSuperview or in traitCollection did change also see description and additional notes Expected Results: layout margins guide should be set according to the layout margins Actual Results: layout margins are set to zero Version: iOS 10.2 (14C89) Notes: more info here: http://stackoverflow.com/a/40334423/2048599 and here: https://forums.developer.apple.com/message/93313 it works if the view is initialized with a bigger size than the layout margins guide - storyboards is using 1000.0 x 1000.0 to initialize and then it works, but it feels icky to use an arbitrary size here Configuration: rMBP with simulator or device - seems it doesn't matter what you use
