Hi all,
I'm trying to learn Objective-C and Cocoa to try and fill the gap that was left by finishing my final year project.
The book I'm reading talks about memory management in code and how you can manually manage memory, or use Garbage Collection to do it automatically.
There are many advantages and disadvantages of using Garbage Collection, but some of the main disadvantages are that OS 10.4 and lower doesn't support it, and neither does the iPhone (at least not at the present).
As Java uses Garbage Collection, I'm used to not having to deal with memory management. I'm wondering how many users might be effected if I use Garbage Collection in Objective-C...
So, what do you guys use?
Thanks,
Ben

Memory management is really not very difficult to get to grips with in Obj-C.
The main rule to stick by is that if you alloc and object in a class/method then dealloc it at the end.
There's a lot of stuff on ... GAH can't remember the name of the site but you post questions and people answer them.

I've voted 10.4 (PowerPC) - that's what we have to use at work, due to the age of the Macs (mainly G5s, some G4s!) and the software we run. To upgrade the software to Adobe CS5 would require a complete move to Intel hardware which the company can't afford at the moment. Similarly, that would require an upgrade to 10.6 which might also have other implications in terms of compatibilty - printers, scanners etc. So we're sticking on our existing setup for the time being.
At home, I'm still on PowerPC, but have now upgraded to 10.5 in preparation for an iPad later this month (hopefully!).

10.5.8 PPC on my venerable PowerMac G5.
Apple tends to be fairly ruthless with their upgrade schedule. They support the current and previous version of the OS and nothing earlier (so currently 10.5 and 10.6). That tends to drive upgrades.

Same here, I'm not sure what we're going to do about CS5, will cost us a fortune. Apple always used to be so good about backwards compatibility as well, but they seem to have abandoned it now.
