I also noticed that on 13.4.1 (and possibly higher) when creating an app project (and possibly others) and going to the target's "Signing and Capabilities" there exists by default an "App Sandbox" which allows/disallows an apps rights to certain things. Even if you have sandbox off, if this section exists the app will adhere to these rules. I fixed it by deleting this section.

I should clarify, upon hitting xcode's play button, the code build successfully, then upon running it immediately quits.
