In Xcode5 there is simple option to Delete derived data:
In organiser menu (cmd + shift + 2):
But with new interface of Xcode6 there is no similar options.
Is there any quick methods to delete this trough Xcode6 interface?
Or now I should remove this folders in system manually?
Update: in Xcode 6.3 (and 7) there is a separate Projects window. Use the Window dropdown menu to find it.
