Question
I am developing an IOS application, using the SBJson library. I don’t use ARC on my project, and previous SBJson releases didn't use it, either.
But now SBJson uses ARC and I have to upgrade to the latest SBJson release. I viewed the SBJson classes and I saw this:
#if !__has_feature(objc_arc)
#error "This source file must be compiled with ARC enabled!"
#endif
How can I upgrade SBJson in my project?
