I am getting an error when trying to run tests on XcodeServer against simulator devices. The tests sometimes pass for one device and fail for another, but the failing device is not always the same one. This can happen in a single session.
The log file error is as follows:

Any ideas would be really helpful.
The simulator requires a user GUI context to run. If the server is launched from /Library/LaunchDaemons then it's running in the system (root) context and doesn't have a GUI context. This is a problem if using Atlassian Bamboo as well as Jenkins for CI. Facebook devs have also encountered this problem with xctool.
You may need to launch the XcodeServer from a user context, i.e. create a plist file in ~/Library/LaunchAgents, and have that user continuously logged in. I would think Apple would have that problem solved during installation.
Try launching this command on the server:
sudo /usr/sbin/DevToolsSecurity --enable
