Xcode's Profiler does not show Symbol names

Updated to xCode 4.5 and when time profiling my app Symbol Name doesn't show classes or objects anymore, but shows memory addresses see below.

0x2fd42e13
0x38014448

I used to see the following

main
NSManagedObjectContext

When I could see the class names then I can track down the issues in the extended detail. Now the extended detail shows the same thing as the 0x2fd42e13.

Solution

  • Solved it myself:

    Edit your scheme where it says "WhateverProjectNameIs>iPad 6.0 simulator"

    Then click on "Profile" on the left On the Info tab, change Build Configuration to Debug (probably set to Release) That should do it. Note that for whatever reason, the build target is not set to the same build configuration as the profile target and this has tripped me up more than a time or two.
