Unknown error -1=ffffffffffffffff occurs when building, running the simulator, running the real machine, etc.
Command /bin/sh failed with exit code1 or Command /bin/codeSign failed with exit code1, etc., once unknown error -1=ffffffffffffffff appears, this kind of error is likely to be a problem with the computer cache, that is, some information has changed However, the local computer still saves the original cache, such as the information in the keychain. Therefore, to solve this problem, the cache needs to be cleared, and the direct solution is to shut down and restart ;
When the command /bin/codeSign failed with exit code1 is reported, that is, codeSign is the code package signature that has changed, but the signature before the change is still retained in the keychain, so, for example, an error is reported when running on the real machine (the first time the project runs on the real machine) When there is a code signature verification, you need to enter your own password to set the keychain code signature
