Adding auto layout should not change the child’s auto layout settings.
When applying auto layout to a parent, the settings of the child’s auto layout width changes for example from fixed to fill, or in some cases from fill to hug. Therefore I have to adjust every child and child’s child again to have things work like I wanted in the beginning. This is a super annoying and frustrating feature.
Keep the child’s settings as they are when adding auto layout to the parent.
