Xcode Archive Error: Missing IOS Distribution Signing Identity For (Name)

Question

When I try to archive my app, I get this error...

I've been doing a lot of research, but can't seem to figure it out. I've tried everything from revoking and recreating my certificates, and recreating the Provisioning Profiles.

What do i do?

Answer 1

According to the Apple Developer Forums, the Apple Worldwide Developer Relations Intermediate Certificate Expiration expired 2/14/2016.

... This issue stems from having a copy of the expired WWDR Intermediate certificate in both your System and Login keychains. To resolve the issue, you should first download and install the new WWDR intermediate certificate (by double-clicking on the file). Next, in the Keychain Access application, select the System keychain. Make sure to select “Show Expired Certificates” in the View menu and then delete the expired version of the Apple Worldwide Developer Relations Certificate Authority Intermediate certificate (expired on February 14, 2016). Your certificates should now appear as valid in Keychain Access and be available to Xcode for submissions to the App Store.

Follow These Simple Steps:

1. Open Keychain from top menu go to View > Show Expired Certificates .
2. Now In Keychain Locate Expired Apple World Wide Developer Relation Certification Authority in Login tab and System tab from left panel and delete it from both tabs.
3. Download Certificate: https://developer.apple.com/certificationauthority/AppleWWDRCA.cer and double click to install it.
4. Restart Xcode.
