How to enable NSZombie in Xcode?

Question

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?

Answer 1

Environment variables are now part of the "scheme".

To edit the scheme and turn on zombies:

• In the "Product" menu, select "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.
