Although I know that this Xcode version is quite old, my company's project still needs to use it and I didn't manage to make it ran properly on my company's mac.
Does anyone have faced this issue as well? Any idea would be very helpful!
ps. On my personal mac, with macOS High Sierra 10.13.1 Beta (17B25c), every time that I try to open Xcode 7.3.1, it crashes and doesn't even inform the reason.
It works on my machine... I know that doesn't help you but I just installed it and it opens ok. Maybe upgrade to full version?
