Objective-c - Packaging certificate issue: No matching coding identity found:

Question

I was able to package it yesterday. I accidentally cleaned up all the items in the keychain this morning, and then I couldn’t package it. I kept reporting this error. I still don’t understand the certificate issue. I hope experienced friends can help me solve it. ~
Thank you~

You need to get the certificate again. The certificate was placed in the keychain and was deleted by you
