Is garbage collection used in production quality Cocoa apps?

Question

I\'m mainly wondering about the affect that garbage collection would have on performance. Is the use of garbage collection frowned upon for release apps?

Another concern

Answer 1

I use GC whenever I can, because the best code of all is the code you don't have to write in the first place. Also, as Bbum pointed out above, running under GC means that you have far more information available for performance analysis, should you need to debug any bottlenecks.
