Same here... Apple said, 15.3 emulator makes crash. but I don't have 15.3.. and the app is working well on 15.3 real device 15.2 emulator also. How could I test the 15.3 on emulator?! @_@;

I have faced the same error. An actual device works well but the emulator makes problem. The errors <unknown>:0: error: unable to load standard library for target 'arm64-apple-ios12.0' <unknown>:0: error: module compiled with Swift 5.4 cannot be imported by the Swift 5.5.2 compiler: And I tried to change my swift version(5.5.2 -> 5.4) on Xcode via ToolChain, but it does not work.
