Hi framusrock -
It looks like in your logs that the OS cannot create a File Service that it needs. So, to test the easiest solutions first, Make sure that the Computer you are packaging or launching from is trusted by the iOS device, Make sure that you have sufficient room on the iOS device itself and finally if you have previously launched an app on the deivce with the same Project name, delete the previous version.
Try those three things and let me know.
