In Xcode 5.1.1 you will find it under Xcode -> Preferences -> Locations -> DerivedData. Under DerivedData you will see a bunch of random directory names. Find the ones that starts with your project name. Then get the latest directory that was created for your project. Then under that directory go to Build/Products/.
You can even click on your end product under "Products" in project explorer and do a "Show in finder" to get there directly.
