Summary:
When trying to launch logic tests from Xcode 8.0 GM Seed for execution with the iOS 8.4 simulator, xctest appears to hang for about two minutes before being terminated by Xcode. The Xcode console shows this:

*** If you believe this error represents a bug, please attach the log file at /.../Library/Developer/Xcode/DerivedData/MyFramework-fqqupyljlrfugubhwmqhwqmxxllx/Logs/Test/6C7E57DB-E96F-41C6-946D-4065E3A27C08/Session-MyFrameworkTests-2016-09-09_094752-6VxHle.log

Program ended with exit code: 9

Steps to Reproduce:
1. Load the attached project in Xcode 8
2. Set the scheme platform to some iOS 8.4 simulator
3. Use ⌘U to run the logic tests

Expected Results:
It is expected that the test suite will run to completion if the iOS 8.4 simulator is supposed to work with Xcode 8.0.

Actual Results:
xctest appears to hang until Xcode kills the process.

Version:
Xcode Version 8.0 (8A218a)
OS X 10.11.6 (15G1004)

Notes:
iOS applications appear to work correctly in the iOS 8.4 simulator when built and launched with Xcode 8.0.

Configuration:
This happens with the Xcode 8.0 GM seed running on El Capitan or the macOS Sierra GM seed.
