After updating to XCode 14.3 on an older MP 5,1 running 12.5.1 and modifying the Info.plist for XCode using these guidelines: Update Xcode 10.1 to 10.2 on High Sierra 10.13.6 everything is working fine, including building to a real device running 16.4, except that the simulators running 16.4 only show a blank black screen. Simulators running iOS 15 work fine.
I looked at the Info.plist for the Simulator.app as well but it's minimum system version is still at 12.0 so there was no change necessary. I also tried replacing the Xcode.app/Contents/Developer/usr/bin/xcodebuild with the one from 14.2 and there was no change so I put the 14.3 one back in place. I also tried rebooting the system, no change.
Unfortunately, due to the AVX2 instructions required for Ventura, updating an MP 5,1 to Ventura with OpenCore has some serious issues. Monterey is very stable and since I can't update my OS, but needed to update my iPhone's OS, I had to move to 14.3.
While I don't often use Simulators, I do need them to work when I need them. Anyone know how to resolve this?
