XCode version：11.3.1 - Catalina After I installed the certificate, open the project. Xcode will automatically create a development certificate, and I can run my project normally. But when I opened other projects of my team, the following problems occurred: Revoke certificate Your account already has a signing certificate for this machine but it is not present in your keychain. To create a new one, you must first revoke the existing certificate. After clicking revoke, I removed the original development certificate and recreated a new one. My current project can run normally, but the problem still occurs when I open other projects. This is new Paid Apple Developer’s Account. XCode cannot recognize my certificate. How to solve this problem? Please help for this solutions. Thank you kindly, CR
