Output from Carthage now looks like...

*** Fetching Operations

*** xcodebuild output can be found in /var/folders/6j/9k2drdbs1fv9fw5d6wng5yzh0000gn/T/carthage-xcodebuild.BZ5ckd.log

*** Building scheme "Operations-iOS-Extension" in Operations.xcodeproj

Partly the reason for this was also that the deployment target of the extension framework was set to 9.0 which is wrong, as we should still be supporting 8.0 - whoops!
