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

Like the others, I would strongly recommend using GC. The performance overhead usually is negligible! I don't need to repeat the benefits as stated by other users.

However, I would strongly encourage writing libraries, as opposed to applications, to run in a non-GC mode as well. Some environments cannot run GC code, the iPhone being the notable one; so if you created an internal library for yourself, that you envision reusing it later for an iPhone app, then I would recommend designing it so it would work in a non-GC environment as well.

Converting a GC code to non-GC code is much more difficult than the other way around!
