XCode iOS Distribution Certificates automatically being revoked

Question

Suddenly I cannot publish a build from XCode to the App Store. My last successful submission was 2 weeks ago and nothing that I can think of has changed. When I validate the publish, I receive the error:

Missing iOS Distribution signing identity for <%name%>

I look in XCode/Preferences/Select profile/View Details and all of my signing identities are revoked.

I have deleted my certificates from the developer portal as well as my key chain and recreated in the developer portal and downloaded to key change as instructed here: https://developer.apple.com/library/ios/documentation/IDEs/Conceptual/AppDistributionGuide/MaintainingCertificates/MaintainingCertificates.html

I have also deleted again and let XCode automatically create my certificate. It automatically gets revoked again.

My membership is up-to-date and as far as I'm aware I have abided by the rules! (Apple certainly have told me otherwise). I have never had an app rejected.

Any ideas? I'm running OSX 10.10.2 with XCode 6.4. Literally 2 weeks ago I was working without issues.

Thanks

Answer 1

The Worldwide Developer Relations Certificate Authority expired on 14 Feb 2016 so you will need to update it but importantly, you need to remove the expired one by selecting View/Show Expired Certificates from Keychain. Ensure that system and certificates are selected

Answer 2

The solution is from the iOS Dev Center and "KeyChain Acces", you need to download the new "Intermediate certificate" file by clicking on Create a new certificate.

1. Click on "Intermediate Certificates" link..
2. Download file
3. Double click

It's solved the problem
