Xcode instruments

The two columns worth noting in Instruments are # Persistent and # Transient. The Persistent column keeps a count of the number of objects of each type that currently exist in memory. The Transient column shows the number of objects that have existed but have since been deallocated. Persistent objects are using up memory, transient objects have had their memory released.
