Random errors when embedding UILabel in UIView inside UIStackView

One UILabel is placed directly into UIStackView the second UILabel is the same but embedded in another UIView: enter image description here enter image description here enter image description here

I need >= constraint due to some more complex layout but I simplified the example. The labels should have the same position on the screen and the same width. But even in this example it causes random layout errors.

Tried to change priorities - it doesn't help. How to resolve this issue?

Solution

  • Found a strange solution:

    Both labels should have "Content Hugging Priority" 750 (High) and "Content Compression Resistance Priority" 1000 (Required).

    If you do it your external stack view will be resized to the widest of 2 labels. And it looks workable even with multiline labels!
