This was a talk I gave at the SWMobile Meetup in Bristol in October 2016. The talk was a lightning talk on automating the new Xcode 8 automated signing system when using it in a CI setup. In our case we use it with Jenkins and Fastlane to automate all our builds. Video at: https://www.quernus.co.uk/2016/10/18/automating-xcode-8s-new-automatic-signing/

10. A couple of notes
• The PROVISIONING_PROFILE_SPECIFIER is kept blank. This is
because this is only used then doing automatic provisioning
• The indirection of PROVISIONING_PROFILE_app and
PROVISIONING_PROFILE means that the profile will only be
used to sign the app itself and not the pods as they are built.
• We set the CODE_SIGN_IDENTITY and CODE_SIGN_IDENTITY
to override anything the developers might have set in their local
configuration.
• We have a separate file for develop, feature and release builds of
our app. They have a different provisioning profile UUID
specified.
