Release Xcode 6 Beta, iOS 7 app to App Store

Question

I've been working on an app for a client and decided to build it in Swift since I knew their release date would be very late in the year, possibly around late November. However, they've now decided to cut features for an earlier release date and I'm a little bit stuck. Can we still release an iOS 7 app built in Swift and Xcode 6 Beta to the App Store? If not, is there some way of building it in Xcode 5 without have to re-write all the swift files, of which there are many?

Answer 1

As far as I know, Swift is only available in Xcode 6 so unfortunately, you will not be able to release it to the app store till Xcode 6 is released.
