Feel free to download and try out Xcode 7. It should coexist just fine with Xcode 6, with the following caveats:Close any production projects in Xcode 6 every time before opening Xcode 7. You most likely don't want Xcode 7 opening them and automatically upgrading things automatically.Keep Xcode 6 around if you have live apps or otherwise might need to submit code to production before Xcode 7 / iOS 9 goes public in the fall.And of course, use source control and regular full backups in case something is different this time.
