Not just intel macs, they are not incredibly slow on Apple Silicon however they are consuming an extraordinarily excessive amount of CPU while they run. Appears to be some internal process crashing in a loop causing diagnosticd to work really hard etc. The famed Apple Silicon battery life performance is quickly neutralized by leaving a Simulator running any longer than you have to. Would love to see a fix for this as it's been a known issue through at least the second half of the Xcode 15 beta process

Hi there! Interesting to hear that about reviews always being on-device, in my experience we suffered a lot of app rejections for Simulator-only bugs in iOS14 with Sign in with Apple, and our library users have reported rejections currently with iOS18 despite it being a Simulator only bug. So our experience is that for whatever reason, sometimes the Simulator-only bugs in Sign in with Apple will cause rejections. That said, I've opened a report here https://feedbackassistant.apple.com/feedback/15905052 - it is difficult for me to create a reproduction that's easy to post on the feedback, as it is a react-native project. Maybe a fully built .ipa file is sufficient though? I could upload that if, if that's okay. I appreciate the response either way, thank you

I tried an export of the test app built for release and signed for App Store distribution but not uploaded, just exported as a file. Attached that to the feedback. Hopefully between my description of the issue and that they'll be able to reproduce and fix it. Cheers
