Codesign returns unknown error after "replacing existing signature"

I am trying to build a Xamarin iOS app using xbuild on Jenkins. Sometimes the build fails during the codesigning process with an unknown error -1=ffffffffffffffff and sometimes the build succeeds. The provisioning profile is stored in a separate keychain jenkins.keychain (not the system or login keychain) that is referenced by Jenkins through the Keychains and Provisioning Profiles Plugin.

This is the console log of Jenkins:

Target _CodesignAppBundle:
    Codesign Task
      CodesignAllocate: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/codesign_allocate

    Task "Codesign" execution -- FAILED

As suggested in Codesign returned unknown error -1=ffffffffffffffff I added set-key-partition-list -S apple-tool:,apple:,codesign: -s -k ${KEYCHAIN_PW} ${KEYCHAIN_PATH} to my build script but it did not fix the issue.

Do you have any idea how to address this issue? Why is there an existing signature to be replaced?

Update 1 - We keep getting the error after:

A similar problem is described in the Apple forum.

My resolution to this problem was ensuring that the Mac had proper permissions to use the new certificate. I was getting this code signing issue when trying to run a Jenkins job, but things ran properly on my local machine. When I tried manually code signing one of the Swift libraries (e.g. libswiftos.dylib), the Mac then asked for a password to be able to use the new certificate. Once I did that, the Jenkins job ran successfully.

Restarting the Mac could Fix the issue
