Same problem. Deleting the file as no effect and I do have read & write permissions, but maybe not execute? IDK because finder doesn't let you add execute. This all worked fine before Xcode12 forced update. Thanks... The more important question is why do people ask questions here? Clearly Apple as no interest in supporting their products.

I can't run the simulator anymore on MacBook Pro & Xcode 12. What's the fix for this? library built using clangm64 -miphoneos-version-min=9.0 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk App built using standard arch linker output: building for iOS Simulator-arm64 but attempting to link with file built for iOS Simulator-x86_64
