Where is Xcode's build folder?
Before Xcode 4 the build used to be created in the root folder of my project. I can no longer find it.
Where can i find the build folder?
~/Library/Developer/Xcode/DerivedData is now the default.
You can set the prefs in Xcode to allow projects to specify their build directories.
It should by located in: ~/Library/Developer/Xcode/DerivedData.
If you changed the defaults, you can see where the build directory is by going to File->Workspace Settings then look at Build Location
