Constraints issues #97

Open igashev opened 6 months ago

igashev commented 6 months ago

Hi,

There seems to be some issues with satisfying constraints. I haven't seen any visual glitches apart from that the message are being choppy when scrolling which might very well be caused by the wrong constraints. Could you please take a look?

Unable to simultaneously satisfy constraints.
    Probably at least one of the constraints in the following list is one you don't want. 
    Try this: 
        (1) look at each constraint and try to figure out which you don't expect; 
        (2) find the code that added the unwanted constraint or constraints and fix it.

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKitCore/UIView.h> may also be helpful.

Thanks for reporting. We'll take a look at it after the other incoming reports, since visually there are no issues seen yet that are caused by this. Ofcourse, we want to resolve it anyway in the end.

In case a visual issue is detected related to this, feel free to let us know.

Hi @igashev , we can't seem to reproduce this anymore in the latest version. Can you check if you still see this happening? And if this is still happening in the latest version?

Please let us know, thanks!
