How to enable NSZombie in Xcode?

I have an app that is crashing with no error tracing. I can see part of what is going on if I debug, but can't figure out which object is "zombie-ing".

Does anybody know how to enable NSZombie in Xcode 4?

Solution

  • Environment variables are now part of the "scheme".

    To edit the scheme and turn on zombies:

    • In the "Product" menu, select "Scheme" > "Edit Scheme...".

    • Go to the "Run Foo.app" stage in the left panel, and the "Arguments" tab on the right.

    • Add NSZombieEnabled to the "Environment Variables" section and set the value to YES, as you could in Xcode 3.

    In Xcode 4.1 and above, there's also a checkbox on the "Diagnostics" tab of the "Run" stage to "Enable Zombie Objects".

    With Xcode 6.4:
