Do we need Xcode 7 & Swift 2 to submit an app?

Our app is almost ready and we don't have the time to upgrade to Swift 2 & Xcode 7. Can we use Xcode 6 to release the app to the app store? I noticed that there is a blog post but it does not clearly state whether we can submit an app using Xcode 6 & Swift 1.2. In that past we have always had to build against the latest version of Xcode and want to know if that still holds true.

Apple has allowed older Xcode to be used for submittals in the past - I believe Xcode 5.1.1 is still ok right now, so you should have no problem with 6.x
