I'm programming my constraints in my video game, which is working good so far until I ran into my most important interactive storyboard. I have three buttons that move back and forth on the Y position each time they are hit. The buttons Y positions only change to view.safeAreaLayoutGuide.centerYAnchor, constant: 100 or view.safeAreaLayoutGuide.centerYAnchor, constant: 200 or view.safeAreaLayoutGuide.centerYAnchor, constant: 300

The strange part is the button that is in the Y 100 stays visible and I can hit the button that is in the Y 100. The buttons in the Y 200 and Y 300 positions are visible until after one or two hits, then the button that is in Y 300 position disappears, then after another hit or two the button that is in the Y 200 position disappears but the button that is in the Y 100 is still visible.

I cleared all my constraints to narrow it down to clear view of the constraints that is causing the problem. I do not think this Log Noise. Below is the error log:

Problem could be that you have multiple constraints for UILayoutGuide:0x3030f0c40'UIViewSafeAreaLayoutGuide'.centerY (related to each button), creating inconsistency when you move buttons as the position of others have not yet changed.

Where (in which func) do you change the constraints ? Do you call viewWillNeedLayout after change ?

Could you post a minimal code example of the issue ?

Why do you constrain to UIViewSafeAreaLayoutGuide and not simply to safeArea center ?

PS: another solution would be to duplicate (or triplicate) the buttons and change their isHidden property as needed.

I do not call viewWillNeedLayout after change. I will provide a code snippet as soon as I can tonight. I constrain to the safearealayout guide because it’s can change depending on which layout you use….ie..iPhone 16max, iPhone 16 Pro, iPhone SE…etc.

Even when I use Auto Layout Constraints, my button behavior reacts the same.

NSLayoutConstraint.activate(constraints)

The buttons have been tested using TopAnchor, BottomAnchor, LeadingAnchor, TrailingAnchor as well.
