running bwoken from jenkins - jenkins

Question

We're trying to set up continuous integration test on our iOS project and running into some issue running broken from Jenkins.
The error we are getting is the following:

I think the important part is here:

mError Domain=com.apple.instruments Code=1 "Error Starting Recording" UserInfo=0x7fa5632b19f0 {NSLocalizedDescription=Error Starting Recording, NSLocalizedRecoverySuggestion=At least one target failed to launch; aborting run}
I can't make sense of it right now, so any help is appreciated.
Thanks, olivier

WE got it running using the jenkins app (https://github.com/stisti/jenkins-app). The issue is related to the fact that Jenkins runs as a deamon and thus does not have access to the window server.
There might be another way around this (changing the Jenkins user type), but running jenkins as an app works for us
