Getting out of treble with Instruments

Sebastian Beswick, Art Processors

Memory management is a crucial part of app development. Apple moved a large part of this burden from the developer to the compiler with the introduction of ARC (automatic reference counting), but a solid understanding of memory management is still a key tool in every developers belt. This talk looks at using Instruments to diagnose memory issues in apps, common gotchas to be avoided, and how ARC simplifies many of these problems.
