<p>Does Apple's Xcode development environment provide any tools for memory leak detection?</p>

<p>I am especially interested in tools that apply to the iPhone SDK. Currently my favourite platform for hobby programming projects</p>

<p>Documentations/tutorials for said tools would be very helpful.</p>

ObjectAlloc and MallocDebug should both be of help to you. If you installed the entire SDK, they will be found in Developer->Applications->Performance Tools.
Their names give you a pretty good clue as to their functions, OA, tracks the objects create and MA is a general memory leak tool.
I haven't tried them with iPhone development yet, but I have to believe that they would work there as well.
Assuming you have registered for ADC iPhone developer site, here the link to follow:
