ios - The identity used to sign the executable is no longer valid

Question

I have an application that I am debugging on iPad. 2 days ago I wanted to debug a same updated application but I am having this error.

The identity used to sign the executable is no longer valid.

Please verify that your device’s clock is properly set, and that your signing certificate is not expired.

(0xE8008018).

I don't have iPhone Developer certificate yet, but I have debugged this game once.

Answer 1

Neither restarting Xcode nor restarting my Mac helped.

Solution within Xcode:

1. In Xcode, go to Preferences --> Accounts --> View Details
2. Press the + symbol and select iOS Development
3. Press the refresh button in the lower left corner (called Download all in Xcode 7)

PS:

• Sometimes it may also help to delete invalid provisioning profiles: right-click -> move to trash
• I saw this error exactly one year after signing up as an Apple developer.
