How to remove a specific Size Class from a storyboard?

Question

I'm worjìking on a testing project. All the project is in wAny hAny size class but I accidentally worked for some minutes in wRegular hCompact, now in wAny hAny there are elements that aren't present in wAny hAny which I refer to in the code, so the I get errors when running the project in simulator. How can I get rid of wRegular hCompact size class?

EDIT Two screenshot of the current situation. There are not constrains but some elements are moved when switching from a size class to another.

Answer 1

You can see which constraints are associated with a view by selecting it and then selecting the Size Inspector button in the Utilities pane.

Double click on the constraint you want to inspect which will show you all the size classes a constraint is installed for. Click on the little X next to the size class that you wish to remove it from. In this case wC hR.
