ios - Alocation instrument in Profiler not showing Application level classes -

i'm running issue using xcode 6.3 beta 3 profiler not showing of custom application classes in list of allocations:

i have multiple classes contain word post none of them show in allocation summary, though being displayed on screen.

i've set app target use debug mode when running in profiler i'm not sure causing issue.

when searching in allocation list can see allocations performed class i'm looking for, no trace of allocation history of class itself:

any idea setting wrong?

update: release of xcode 6.3 (6d570) can memory profiling work expected on device:

however, still not working on simulator.
