I have followed the extra diagnostics provided: 1. Created a new test project from one of Xcode’s built-in templates with automatic code signing enabled. I was not able to run the test project on the device. 2. Created a new user on my Mac, logged out of my current user, and logged in as the new user. I repeated the previous step and still was not able to run the app on the device. Despite following these steps, I am still encountering the same error: “Failed to verify code signature of /var/installd/Library/Caches/com.apple.mobile.installd.staging/temp.SznYNY/extracted/iForC.app: 0xe8008018 (The identity used to sign the executable is no longer valid.)”. I would appreciate further guidance on resolving this issue. Thank you.

I did but still have that problem !

I try new app , new Mac , new device but still have the problem ! I called apple Support said revoke certificates , but I did many many times , and call again and nothing new , Problem still here @eskimo pls help me

Hi, I tried logging in with a different Apple ID and was able to run the app, but that ID is not a developer account, so I couldn't build my project because it uses In-App Purchase. Do you have any solutions for this issue with my main developer account? I called developer support but they couldn't resolve the problem. I would really appreciate your help with this. Thank you very much,

anybody can fix that problem pls let us knoww plsssss
