I have been seeing on web that latest update for Xcode -Xcode 7 beta release has arrived. I currently have xcode 6.4 and i cannot see any update on Appstore. Where can i get it?
From the Apple Developer Downloads page - https://developer.apple.com/xcode/download/
The App store doesn't have Xcode 7 yet since it's still Golden Master status and not released to the world via the App Store downloads.
