The HStack is meant to be column headers for the list items and need the same styling This seam to be a short fall of lists in the dark mode.

I tried to put the HStack is a List but this does not look good because the other list has a ForEach where the whole background in Dark Mode goes black but the HStack leaves the outer background its List white. Why does not ever area in dark mode black for all elements is a list here either. Dark Mode should make all background Black. Non of the Pad OS should be white.

I actually found a rogue line I had added which caused what happened and it was not the sort. It did take some very detailed debugging to find. Sort is off the hook this time. After 50 some years of coding I can still create bugs requiring very detailed debugging. Still have a few features to get working but it runs on my iPar Air and my Mac Pro and looks good so far.

I had to reboot and re-apply trusted developer status. This is an iPad Air about a week old. My iPad Pro 10. never took status away by just rebuilding. Is this a bug? I am also learning where the preferences are on this iPad. I have been using the iPad Pro do this for years without ever seeing this happen. I have done software for over 50 years. Is there a fix for this. My wife is now using my Pro and I want to use my new iPad air. I do not want to have to do this every day.

Final solved this problem. The iPad Pro password was wrong in the Apple ID. Corrected the password and code now loads and run again.

Travis You hit the nail on the head but I never remember touching the debug menu ever. That did make the simulation very close to what I see on the real hardware. Thanks. I even see iPhone 11 sim looking like I would be happy with the performance on a real hardware one. Thanks again, I saw several checks on that menu I would never have said I ever selected.

Thanks, The animations are not slow duration 0.75 to 1.5 but on simulations that is 15 to 1 in performance. Multiple things are happing on 1 card flipping and having things rotating on one surface. Without real hardware this is impossible. I would also like to know is looks good on multiple targets. I not sure how to trust using only one real target represents all hardware when testing. Simulation these things are completely untestable. I do know how important testing have written embedded software for aircraft for 47 years. I would expect debug to slow things down.
