Summary:
When we attempt to run unit tests via ssh on another Mac the unit tests fail because the simulator fails to launch.
Steps to Reproduce:
1. Install Xcode 6 beta 7 onto a remote machine
2. Copy the attached project to the remote machine
3. SSH into that remote machine from another Mac
4. Run the unit tests via command line
xcodebuild -project UnitTestJenkinsTest.xcodeproj -sdk iphonesimulator8.0 -scheme UnitTestJenkinsTest -verbose clean test
Expected Results:
The unit tests run on the remote machine, like they did under Xcode 5.
Actual Results:
The unit tests time out with a simulator failed to launch error:

If that's the case, why does it happen also on Xcode Server 4.1.3 and Xcode 6.3?

The context provided by LaunchDaemons is not supported for running GUI applications. The SSH service, and the default setup for Jenkins, are both implemented as LaunchDaemons. In earlier versions of Xcode 5 xcodebuild could run tests on the iOS simulator in this context, but that was never a supported configuration, and as you have noted that is no longer working as of Xcode 6.
Unlike LaunchDaemons, LaunchAgents provide a context where you can run GUI applications - if the user is logged in at the time, with a window server / Aqua session. Converting your Jenkins configuration from being a LaunchDaemon to being a LaunchAgent would avoid the reported issue. You can also use launchd for running tests on the iOS simulator from a SSH session, either by crafting a LaunchAgent and manually loading / starting that, or by using "launchctl submit”.
