> Apple tried to implement a garbage collector but they abandoned it later. May be they don't have good developers (but they got a lot of money so they probably can buy anyone) or reference counting isn't that bad in practice. Garbage Collection is not very good with a C-language. C is simply the wrong language to be used with GC - same for Objective C. Personally I would also not use a 'conservative GC' in this context. Additionally GC has some overhead and it is not going away: memory usage, responsiveness, etc.. Apple would need to switch to a real higher-level language with managed memory and a precise GC. GC, Swift and more RAM might have more chances.
