/usr/bin/codesign failed with exit code 1
I had the exact same error, and tried everything under the sun, including what was elsewhere on this page, with no success. What the problem was for me was that in Keychain Access, the actual Apple WWDR certificate was marked as "Always Trust". It needed to be "System Defaults". That goes for your Development and Distribution certificates, too. If any of them are incorrectly set to "Always Trust", that can apparently cause this problem.
So, in Keychain Access, click on the Apple Worldwide Developer Relations Certificate Authority certificate, select Get Info. Then, expand the Trust settings, and for the combo box for "When using this certificate:", choose "System Defaults".
Others have commented that you may have to do this in System and login keychains for these errors.
It might be strange answer for codesign issue in Xcode 9.0. I was receiving this error too and did not know what to be done, because everything was correct.
I went to the keychain, I had the login option "unlocked". I locked it and compiled my build again. Xcode itself asked me to open access keychain. I gave access and it worked.
Steps were:
- Go to keychain
- Lock it
- Archive the code, build the project again
I just came across this error, and here's what I found out in case this helps anyone: I discovered that you can right click the error message in Xcode and choose expand to get more details, including a description of the problem.
In my case, I had two copies of my developer certificate with the same name in different keychain files, and Xcode couldn't figure out which one to use.
Update:
The Technical Note in my original answer is now deprecated. Apple posted a collection of code signing problems (and some solutions) in a new document: Technical Note TN2407 Code Signing Troubleshooting Index
Check the CODE_SIGN_IDENTITY property in your build settings. Is your provisioning profile selected there?
You also need to enter a valid bundle identifier in your apps .plist.
The identifier has to match the one you provided when generating the profile.
Apple has a technote about that here.
