Is there any good treatment of Xcode code and memory out there? Like any book or resources? I am mixing Objective-C and plain C within an Xcode project and the memory usage keeps on growing. I am interested in in-depth treatment of the underlying concepts as well as tools including Apple Instruments. Something like 100 pages would be very welcomed.
Apple has several documents about memory management. For instance:
Even if the second one is about CF, it also explains lots of concepts available in Objective-C.
There are also great videos about memory management on the WWDC sessions, especially about OS X (or iOS) memory management internals and Instruments.
You can download them from iTunes if you’re a registered developer:
