Q: No codesigning identities found

I recently wiped my Xserve, installed a fresh copy of 10.10.3 and Server (4.1) I added a bot, but when it tries to build the source, I get the following error:

Code Sign error: No codesigning identities found: No codesigning identities (i.e. certificate and private key pairs) that match the provisioning profile specified in your build settings (“Provisioning Profile") were found.

CodeSign error: code signing is required for product type 'App Extension' in SDK 'iOS 8.3'

Any suggestions would be greatly appreciated.
