I am keen to know whether someone figured this out.

The error happens to me too and I have way less data now (4 rows). I have an M1 mac with 32 GB ram.

I followed your sample code but there's one catch. My button (that triggers the share sheet) is on a sheet as well. Not sure if that's causing the below issue: 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. 2022-07-08 15:19:09.297048+0100 Cluedo Notes[68004:12824046] [LayoutConstraints] 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.  (   "<NSLayoutConstraint:0x28029f200 _UIActivityActionCellTitleLabel:0x1293c41c0.height >= 22  (active)>",   "<NSLayoutConstraint:0x28029ecb0 UIView:0x1293c32e0.height >= _UIActivityActionCellTitleLabel:0x1293c41c0.height + 30  (active)>",   "<NSLayoutConstraint:0x2802881e0 'UIView-Encapsulated-Layout-Height' UIView:0x1293c32e0.height == 30  (active)>" ) Will attempt to recover by breaking constraint  <NSLayoutConstraint:0x28029f200 _UIActivityActionCellTitleLabel:0x1293c41c0.height >= 22  (active)> Any ideas on how to resolve this? This isn't causing any trouble to my app but I do not like to see messages on my console. Last but not least, thanks a mil for your sample code. Using Swift 5 and iOS 15

Thanks for the answer. Any ideas or pointers on how to update a Preference Pane?

If both apps are configured to stay on top of all other apps then the most recent app activated stays on the top.And, regarding apps staying on top, yes, you can easily configure it by setting the appropriate Window Level.
