All your provisioning profiles should be located in ~/Library/MobileDevice/Provisioning Profiles
.
If you wish to view the contents of a profile, type:
security cms -D -i <XXXX.mobileprovision>
Sometimes you may have obsolete provisioning profiles (i.e removed, expired, etc.):
rm -rf ~/Library/MobileDevice/Provisioning Profiles
You can also go to Xcode and visit Xcode
->Preferences
and removing your account attached and readding.
If you want to find out what code identities currently installed, you can type:
security find-identity -v -p codesigning
