-Subject: Remove MTLManagedObjectAdapter.h
-
-We are using an outdated version of Mantle which leverages NSConfinementConcurrencyType,
-an enum which has been deprecated with no replacement as of macOS 10.11.
-The actual solution to this problem is to upgrade Mantle, but for now
-we just stop building the offending adapter.
