Can I use Swift 2.0 for an application to be submitted before Xcode 7 goes final? The re a lot of new features that look great and I'd like to ise them now. Not develop in 1.2 and then rewrite in 2.0.
Swift 2.0 App Store submittion
Historically it was possible with the gold master release of Xcode. So a few days before iOS9/OSX10.11 goes live probably.
