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?
Pressing Cmd + Shift + 2 In Xcode 6 will present Devices, which is separated from Organizer. Instead you can go Window, then Organizer, then find your project in Projects to delete derived data. You may set a short key in Key Bindings for quick access to derived data.
