Same thing for 1.8.3

You do need to run git submodule update --init --recursive after you cloned the repository.
We use submodules for a shared set of configurations of Xcode config files, which also includes the configuration on whether to enable ARC (which is the error that you see here).

TL;DR Run this to unbreak:

git clone https://github.com/BoltsFramework/Bolts-ObjC.git
cd Bolts-ObjC
git submodule update --init --recursive
