iOS - Objective-C - Enable ARC

Hello everyone,

I’m working on an AR app for iOS using Unreal Engine. I’m adding a lot of Objective-C code and just noticed that ARC is not enabled by default.

According to the documentation, I can add the following variable to my .Build.cs file:
bEnableObjCAutomaticReferenceCounting

Does anyone know if it’s safe to use, or will it introduce bugs at some point? I can see lot of engine plugins using retain and release.

Thanks in advance!
