Fix Xcode Error "The identity used to sign the executable is no longer valid"

Workaround from: http://stackoverflow.com/questions/7088441/the-identity-used-to-sign-the-executable-is-no-longer-valid/14275197

Restarting Xcode didn ' t work for me. What fixed it for me is going to Accounts in Xcode (in preferences), Details for my developer account then clicking the R Efresh icon at lower left. That loaded a new team provisioning profiles, which apparently was needed ... yeah. We shouldn ' t has to deal with this Apple. Microsoft used to does this stuff to developers, don ' t go there. –ESKIM0 Mar 9 at 3:34

Steps:

1. Open Xcode configuration (Xcode-Preferences ... ）
2. Select the Accounts page, select your Apple ID, point to the bottom right of the "view detail..." button
3. Click the Refresh button in the lower left corner, wait for the refresh to complete, click the "done" button, close the Xcode configuration window
4. Recompile the run project, if a repair window appears, "fix issue" button

There are other workarounds, see the link above.
