I cannot build any of my apps for iOS (development) due to a code signing error. I have contacted Apple Technical Support about this issue because I initially thought the problem was on their end, but they have since told me they cannot help me because they think the issue relates to Corona's software. The versions of Corona SDK I have used which reproduce the error include 2019.3326, 2019.3480, 2019.3486, and 2019.3490.
I noticed an odd behavior occurs when Corona finishes building the apps. After the build is complete, a login prompt pops up asking me to enter my password for code signing the applicable provisioning profile (see attached screenshot). When I enter the incorrect password, the login prompt wiggles side to side indicating it rejected my password as expected. However, when I enter the correct password, the login prompt disappears momentarily and then reappears to ask me to re-input the password. When I re-input the correct password a second time, the login prompt disappears and does not reappear. I then receive a notification that the app has been successfully built. However, I always receive an error message that code signing has failed when I attempt to upload the built app to my iPhone via Xcode (see attached screenshot).
Keychain access shows my development certificate and corresponding provisioning profile as valid. My membership status as an Apple Developer is also active as I just renewed my membership, so my certificates are not expired. I have also tried revoking and recreating certificates and provisioning profiles several times within the Apple developer portal, but this does not resolve the code signing issues.
This issue has resulted in a significant delay in publishing my apps, so any suggestions about how to resolve or troubleshoot this issue would be much appreciated. I am using a Mac Mini (late 2014 version) running on Mojave 10.14.5 and Xcode 10.2.1 for building.
