TeamCity + Xcode 6 - Run Test action fails

I am trying to make a simple Xcode project work with TeamCity. Without running any tests I have succeeded.

I have a basic, Single View Application in Swift with one label on the screen. Both TeamCity (9.0.2) and Xcode (6.1.1) runs on the same machine (Mac mini) with an OS X (10.10.2) Server (4.0.3) installed on it. I have created a Git repository with Server and added as a remote to my sample Xcode project. After that, I've created successfully a working TeamCity project and build.

However when I try to check the Run tests checkmark the build WILL fail no matter what I do.

Error message (and the messages right before that)

Main problem I found with this error code and CI that they were trying with ssh and there were no GUI session. Currently I have a valid GUI session with the same user it uses, so it shouldn't be a problem.

The xcodebuild command is the following.

/Applications/http://ift.tt/1cDvaGw -workspace FirstTeamCityProject.xcodeproj/project.xcworkspace -scheme FirstTeamCityProject SYMROOT=/Library/TeamCity/buildAgent/work/55b27ad210b8fe77/build OBJROOT=/Library/TeamCity/buildAgent/work/55b27ad210b8fe77/build clean build test

What is missing here (I suppose) is one or more destinations. I've executed the following command and it worked just fine. (Opened the Simulator, then exited with success.)

xcodebuild test -project FirstTeamCityProject.xcodeproj -scheme FirstTeamCityProject -destination 'platform=iOS Simulator,name=iPhone 6,OS=8.1'

I seem to be alone with this problem, I didn't find any other relevant hits. Looking at this tutorial: http://ift.tt/1GyMvMV, my issue should not be present at all.

I appreciate any idea you have! Thanks in advance!
