Obj-C only uses ARC for a minority of the objects.
Really? Every Obj-C API I've seen uses Objective-C objects, which all use RC.
And what about all allocated items?
A UI is a good use case for ARC. A UI doesn't require high performance.
I've written video processing/players on iOS, they all use blocks and reference
counting, including to do date/time processing per frame. All while using RC
network buffers. And it works quite smoothly.
And did you use ref counting for all allocations and all pointers?
There's no doubt that ref counting can be used successfully here and there, with
a competent programmer knowing when he can just convert it to a raw pointer and
use that.
It's another thing entirely to use ref counting for ALL pointers.
And remember that if you have exceptions, then all the dec code needs to be in
exception unwind handlers.
