I am new to xcode and ios development. recently I've seen the xcode releases with, for example xcode 6.0 GM and then xcode 6.0. I wonder what should we do with the GM or we need to wait until the non GM release in order to build ios app.
could anyone explain me about this ?
Xcode 6.0 GM (Golden Master) is the version released before 6.0, and it can be used to build & submit to App Store, which is not possible with other betas.
This is necessary because apps should, ideally, be updated before a new iOS is officially released. Waiting for the official new Xcode would be too late, since it is always released with the new iOS.
