Xcode 7 error: “Missing iOS Distribution signing identity for …”

From Apple –

Thanks for bringing this to the attention of the community and
apologies for the issues you’ve been having. 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.

As noted in a comment below, the expired certificate also needs to be removed from the login section, as well:

To all that cannot get it working despite the instructions… There
are two expired WWDR certs. One is in login keychain, and the other
one is in the System. You have to delete both of them in order to make
things working
