Automatic reference counting, is it good?

[Fei Ng]

Is the new automatic reference counting a good replacement? Is there any thing to watch out for? Any performance hit? Or is it better to do it the old way on the old iOS deceives? It really looks too easy than the old retain/release.

Hi Fei,

no, it's not good. It's AWESOME! There is no performance hit, since it happens at compile time, not at runtime.
Watch this video from WWDC 2011 about it: https://developer.apple.com/videos/wwdc/2011/includes/introducing-automatic-reference-counting.html#introducing-automatic-reference-counting

Cheers,

Johannes
