Hi,
I'm trying to understand Xcode 5's memory utilization report pane. When I
debug my iOS app (on the device), memory usage as reported by Xcode almost never
goes down, while when using Instruments' Allocations instrument, mem usage goes
up and down as objects are allocated or deallocated.
Top mem usage is the same for both variants.
Of course I expect differences (Xcode runs a debug version, Instruments runs the
optimized release build), but Xcode makes it look as though I leak most of the
allocated memory, where the leak instrument tells me everything is alright.
Can I just ignore the memory pane in Xcode?
I'm using Xcode 5.0.2.
Regards
Markus
