Does Apple's Xcode development environment provide any tools for memory leak detection?
I am especially interested in tools that apply to the iPhone SDK. Currently my favourite platform for hobby programming projects
Documentations/tutorials for said tools would be very helpful.

The best approach to checking for the existence of a memory leak in your application is by looking at your RAM usage and investigating the total amount of memory been used versus the total amount available. Evidently, it is advisable to obtain snapshots of your memory's heap dump while in a production environment.
The primary tools for detecting memory leaks are the C/C++ debugger and the C Run-time Library (CRT) debug heap functions.
The basic implementation is actually pretty simple. You just maintain a lookup table of every allocation and its line number, and remove the entry when it is freed. Then when the program is done you can list all leaked memory. The hard part is determining when and where the allocation should have been freed.
There is one specifically called Leaks and like a previous poster said, the easiest way to run it is straight from Xcode:
run -> Start with Performance Tool -> Leaks
It seems very good at detecting memory leaks, and was easy for a Non-C Head like me to figure out.
