Uploading archive error: "Missing iOS Distribution signing identity for ..."

ios xcode provisioning signing

I'm trying to upload my iOS app archive to iTunes Connect using Xcode, but when I click "Upload to App Store" I get the error:

Xcode attempted to locate or generate matching signing assets and failed to do so because of the following issues. Missing iOS Distribution signing identity for _____. Xcode can request one for you.

I'm really confused, because I had just successfully uploaded an archive for the same app about 2 hours earlier, and then I needed to make one simple fix and then needed to reupload the archive, and now I'm getting this error. I did not touch anything else.

I've done everything that I can think of to try fixing the problem, I restarted Xcode, my computer, went to Xcode preferences to click 'Download All' on the provisioning profiles, clicked "Reset" on the iOS Distribution on the same page, downloaded again the iOS distribution profile from the member center, went to the code signing settings in my app's build settings and manually set the release signing identity to the iOS distribution profile, and rearchived several times.

Update: Turns out it's due to the WWDRCA expiring today: https://developer.apple.com/support/certificates/expiration/ There are a lot of other people experiencing the same issue. I was able to temporarily bypass the issue by changing the date on my computer back 1 day.

The issue is because the Apple WWDRCA expired today (Feb 14, 2016): https://developer.apple.com/support/certificates/expiration/

Open Keychain Access, and in the menu, click View -> Show Expired Certificates. Then, delete the expired Apple Worldwide Developer Relations Certificate Authority from both the login and System Keychains. Install the renewed certificate from Apple by downloading from https://developer.apple.com/certificationauthority/AppleWWDRCA.cer and then opening it.

Also, you might need to restart Xcode to reflect the changes. Then, clean and build your project then re-try generating your archive.

Your keychain should show like that
