Summary:
Attempts to run unit tests via the command line fail if the parent process originates from ssh.

This manifests with unit tests being invoked by Jenkins, where the Mac is a build slave running the slave.jar invoked by the Jenkins master via ssh. The failure is observed even when the same user is also interactively logged in to the machine. I can see the Java process in the dock, and prior to Xcode 6, I could sit here and watch the Simulator fire up when the tests ran.

Note that there *is* an active GUI session.

Steps to Reproduce:
1. ssh into the Mac from another machine.
2. Attempt to build and test an iOS target using xcodebuild:

xcodebuild -workspace ./Kashoo.xcworkspace -scheme 'Kashoo Dev' -destination 'platform=iOS Simulator,name=iPad' test

Expected Results:
iOS Simulator is launched and unit tests execute.

Actual Results:
The Simulator does not launch, the build job hangs, eventually times out and fails. The following is logged to stdout:

2014-09-11 13:52:40.314 xcodebuild[55004:3c07]  iPhoneSimulator: Timed out waiting 120 seconds for simulator to boot, current state is 1.

Testing failed:
	Test target KashooLogicTestsDev encountered an error (Timed out waiting 120 seconds for simulator to boot, current state is 1.

** TEST FAILED **

Version:
Xcode 6.0 GM (6A313).
Mac OS 10.9.4 (13E28).

Notes:
This is a regression with Xcode 6.  The existing configuration worked correctly with Xcode 5, and Xcode 4 prior to that.
