I was able to run iOS simulator fine with Xcode 14 and my Mac recently updated the latest version of Xcode which is 15 then I’m no longer able to boot a device from its new simulator.
I did try many different ways collected from many sources but no avail. Here are the few things that I already tried and none of them worked for me:
- Remove all the Xcode caches from Storage either from cli or UI as suggested from here: Flutter: XCode error "Unable to boot the Simulator"
- Try all possible answers from here: https://developer.apple.com/forums/thread/667088
- Follow this article: https://medium.com/@liwp.stephen/my-solution-to-solve-unable-to-boot-the-ios-simulator-39bbb4aad100
- Reinstall Xcode with removing all related files: https://byby.dev/uninstall-xcode#:~:text=Delete%20old%20simulators%20and%20devices,moving%20them%20to%20the%20Trash.
- Downgrade Xcode to v14
BTW here is the full log that I collected as run it via cli:
xcrun simctl boot 39C3D624-968A-49F7-A155-AC9AC1A81B52

I guess you have destroyed the integration of the simulators, but you don’t need to do something with the Xcode cause they are separated totally.
Solution
deviceType
andOS Version
.I had the same case, in my case installing additional old Simulator (it was 16.4 sim runtime) solved the problem. After installing Sim 6.4 and rebooting my mac – voila, suddenly even 17’th Sim started working
