So it turns out that the 'Skip Install' was changed to 'YES'. No idea how that happened as I didn't change the build settings - rarely do, tbh. I'll just put this down to experience.....

I've just found this problemn in my Swift app as well. Never had it before and can't see a purple warning about UI manipulation on thread. Only happens occasionally...

Ok, so not an answer, but writing here for the watching members to receive a notification: I've now found that, in my case, it happens when I use a build scheme for a universal app to run under Rosetta: I haven't had a chance to check if such a build, when running on an Intel machine, also kicks out so much guff. I'm hoping it's queit when on a non-Apple Silicon machine. If I switch to an Apple Silicon only build scheme then it all goes quiet. I'll log this as a bug.

@jeffpek42, can you put a regex pattern into the console’s filter to at least help you see other errors? I’m not in front of the computer so am only guessing….

It suddenly seems to have stopped. Not (seemingly) linked to an update, but now it just throws out about a dozen lines and then goes quiet. As one of the answers says: it’s a bug. I suppose. I haven’t changed any code related to the sprites.

There are a few ways to fix (apparently). Personally, I had to unpair the device in Xcode and restart the iPhone. Reconnecting it and leaving the 'Devices' window in Xcode to do it's thing fixed it for me. But there's also answers here: https://www.reddit.com/r/iOSBeta/comments/q1onth/ios_151_device_support_file_for_xcode/ https://stackoverflow.com/a/68378023/372347 Hope one of these works for someone!
