ERROR ITMS-90034: Missing or invalid signature
I have just got the same issue. I have restarted XCode
and it works like a charm!
I have not changed anything and it was working an hour ago; therefore, I did not spent any time on keychain
. I have simply restarted XCode
and it has worked.
If the problem still persists, then I recommend you to Go to Keychain Access, delete all the expired certificates, and add the corresponding valid certificate.
I got the same issue today. My app was sent successfully, but after 10 mins I got an email. with this Error ITMS-90034. As result, I started to check If my profiles are expired and etc. Everything was fine. So maybe after few hours I just sent a new archive, and it was successfully uploaded. I guess it was related to the apple side.
