Game not running correctly on xcode‘s simulator

Unity Engine

Hello,
I asked a related question on Unity answer, but it seems like this situation will require some exchange to be fixed: http://answers.unity3d.com/questions/1065597/game-not-running-correctly-on-xcodes-simulator.html

I am building my game for the simulator, but when I run the simulator in xcode, the simulator just show a blue screen. I can’t test with an actual device to know if the problem is there too. The game work perfectly on other platforms.
I tried to build a new empty project and I got the same result (it started once though without doing anything special, but never again).
I also have a 347 warnings from Xcode: Il2Cpp classes, Bulk_mscorlib_x, etc (is that normal ?)

I am using unity 5.2, the mac is a new mac mini ($499 version) with unity and xcode freshly installed

Any idea ?

I finally got my apple developer licence and a device, everything is working on it. Still no clue about the simulator problem.
