Zombie Processes from iPhone Simulator?

StackOverflow https://stackoverflow.com/questions/15812064

Question

I've been working on apps for a while now and have just recently started noticing these zombie processes being produced for every launch of the app? I've now closed out Xcode and the simulator but they're just sticking around. Is there some new better way of testing your apps on the simulator that avoids this and/or why might this be occurring?

Solution

This is a bug in Xcode 4.6.2 and earlier. It is fixed in Xcode 4.6.3, released yesterday (2013-06-13). I just talked to a couple of Apple engineers about it this morning at WWDC.

OTHER TIPS

Just edit your target scheme -> Click right next to stop button in Xcode on your target, choose Edit Scheme, then go to Diagnostics tab and uncheck 'Enable Zombie Objects' option. Or eventually check your Arguments tab and be sure there's not NSZombieEnabled argument enabled.That should do it
