I was trying to open instruments in xcode 4 but was not able to find a way to do it. Usually in Xcode 3, we would do run -> run with performance tool... but I dont really find any such thing to do it in xcode 4.. would anyone be able to tell me how to do this?
If you want to use Instruments with your product:
Product -> Profile
This brings up a dialog where you can choose Leaks, Allocations, etc.
