iOS Build to Device Not Working when Deployment Target is below iOS 13.0

Question

Background:

Everything worked fine a few days ago... I was able to build to device apps with a deployment target of 10.3. Today, they will only build to devices when the deployment target is set to 13.0+. There is zero issues when building to the simulator. I did not perform any update to my OS or XCode prior.

Build Errors:

error: The specified item could not be found in the keychain.
error: Failed with exit code 1 

It's throwing these errors on some of the swift libraries.

What I've tried so far:

• Did the whole close Xcode, delete Derived Folder, Open Xcode, Clean Build, Build
• Revoked and issued new Certificates via Apple Developer Portal and removed old ones
• Moved the keys to System in keychain
• Uninstalled and reinstalled XCode (was running 11.3.1 and currently running 11.3.1)

What to do next?

I haven't had much luck in my research of more things to try other than I read someone had to reinstall their OS... I really don't want to have to do that...

Thanks in advance.

Answer 1

The only option is to reinstall your OS as keychain problems are solved by reinstalling the OS. As once i forgot my keychain password and when i recover it back it was showing problems in making builds so i have to reinstall my OS.

Answer 2

Magically, this was solved when I was able to update to Catalina...
