Xcode 8 intermittent failures due to different builds



We’re getting some funkiness with our Xcode 8 builds. The failing builds are running on non-GM versions of Xcode whereas the passing ones are on the GM (identified by the code-select phase sha)

Is there a way to require a specific build version? e.g.
version: "8.0"
build: “8A218a”
(that didn’t work)

Any help pinning this would be great


Xcode 8 general release is now available on Circle CI with the machine: Xcode, version: “8.0” setup (as of 10am EST September 15th).

Would still be useful to be able to pin beta builds to a version
