Hello, been beating my head against the wall for a few days with this. Originally got the error in Xcode 16, through the course of troubleshooting uninstalled and reinstalled Xcode multiple times, upgraded Xcode to 23 - same result. Create a different user on my computer and try, same result.
Xcode > Settings > Components show both iOS 26.0 and iOS18.6 simulator, however no simulators show in Xcode, and Xcode hangs when you try to create one.
'xcrun simctl list runtimes' shows this:
iOS 18.6 (18.6 - 22G86) - com.apple.CoreSimulator.SimRuntime.iOS-18-6 (unavailable, liblaunch_sim.dylib could not be opened) iOS 26.0 (26.0 - 23A343) - com.apple.CoreSimulator.SimRuntime.iOS-26-0 (unavailable, liblaunch_sim.dylib could not be opened).
Does anyone have any ideas on what the issue could be?
