ERROR ITMS-90034: Missing or invalid signature

Question

Every time trying to submit but some result. Like this

ERROR ITMS-90034: \"Missing or invalid signature. The bundle \'****.******.****\' at bundle

Answer 1

i was facing same issue, i was selecting Automatically Signing on xCode and manually distribution certificate at uploading time. then i tried manually certificate on both places.(Xcode and TF.) Now it's working fine.

Answer 2

This issue can be raised because of distribution certificate with private key not present in the keychain or revoked from apple developer account.

We can fix this issue by two ways :

1. Create distribution certificate on apple developer account. download it and add it in keychain. Make sure this certificate is added in login section with private key.
2. If distribution certificate is already created on any other machine that time you can take distribution certificate with private key by selecting distribution certificate and private key, export both items to specific destination path. After take that certificate and add it in keychain.

Happy Coding ...

Answer 3

I resolved many times
1 check AppleWWDRCA certificate if expired or not.
2 check fields for always trust by double click the distribution certificate in keychain.
3. I was using another distribution certificate from same name with another expiry date.
4. update/delete previous distribution installed certificate
