An issue is that the previous releases still exist (retail Mac OS X Leopard boxes are still 10.5?) and that someone may need to support them. And in these cases, I would consider that retain/release is more reliable.

Let me re-emphasize one point: I'm referring to new development. Given the APIs and technologies in Leopard, its maturity within the marketplace, the sales rate of Macs, the typical multi-month app development cycle, and the extremely high upgrade rate for previous owners, targeting new development to Leopard only makes a lot of sense.


I have a stupid question too. Considering that I sometimes see warnings in Console.app related to Garbage Collection, does this mean that:

- the issue is in the application (Xcode sometimes display warnings for instance) and not in the GC?

or

- that GC is more complex than retain/release in some cases?

The warning you are referring to is likely this one?

6/2/08 11:31:59 AM [0x0-0x4a34a3].com.apple.Xcode[21294] Xcode(21294,0xb0103000) malloc: free_garbage: garbage ptr = 0x39f3fb0, has non-zero refcount = 1

It is a known bug in the Apple frameworks that is unfortunate, but harmless at runtime.

It is no indication of GC being more complex. It is simply a bug in Mac OS X, of which there are several :), and some of the bugs cause noise in Console, GC or otherwise.
