Solution:
1, go to the key chain to see if the certificate is invalid. If the certificate is invalid, (compile directly, Xcode will report an error, and then click Modify, Xcode will help us automatically download a new certificate, and then we can run it), or go to MC to download the installation certificate. If all the certificates are valid, then we can start the exam directly from the second step.
2. Re-edit the invalid configuration file and rename it->; Download-> Install->; Just switch profiles in xcode.
Details: There is an appeal error. Xcode tells us that the form ID we used to sign is invalid. The easiest way is to delete the invalid certificate and recompile the project.
