I am facing a recurring issue with Xcode iOS simulator. I want to preview a SwiftUI for iOS in Xcode, but the Simulator app fails to boot up. I receive the follow error in Xcode: Cannot Preview in this file. Simulator was shutdown during an update. I have tried the following: Deleting Xcode cache Reinstalling iOS Simulator runtimes Completely uninstalling Xcode and deleting all developer data, then reinstalling None of the above steps fix the problem. The only fix I have found is to completely reinstall MacOS 15.4.1. THIS IS TERRIBLE! I have already reinstalled MacOS 15.4.1 once to fix the issue, and I don't want to do it again. If there is another solution, please help me find it! Thank you!!
