My iOS certificate is stored in GitHub and it is expired, the failure message in circleci progress is that ‘Your certificate 'xxxxxxx.cer' is not valid, please check end date and renew it if necessary’.
Do I need to create a new certificate, or download an existing one? I don’t remember how this was originally created, I thought it was done by Fastlane as part of the build.
But I don't know how to modify the Fastlane command, I have tried to add the 'cert', but it fails.
You can use fastlane match development after deleting the development profiles and certificates from your git repo. Alternatively, you can delete everything from git repo and run fastlane match
If you do not care about existing profiles and certificates, just run fastlane match nuke development and fastlane match nuke appstore, then fastlane match development and fastlane match appstore. These commands will first delete everything from your git repo and apple developer portal and the next two commands will create everything on your apple developer portal and push them to your git repo.
