Build app.. and then i get this?

Well, i opened my project today, went to build my app again after making 1 or 2 small changes, and i get this:

Application failed codesign ve开发者_开发知识库rification. The signature was invalid, or it was not signed with an Apple submission certificate. (-19011)

Any ideas how to fix this?

check your project (and target) settings, which developer profile is used. You probably have install a new developer profile and this project still use an old one.

check certificate in keychain access and provisioning profile code_sign_identity need consistent.
