Can I submit Swift 2.2 app with Xcode 7.3 when iOS 10 is released?

Question

When iOS 10 be released, will I be able to submit to the app store app that runs with Swift 2.2 and was built with Xcode 7.3? Or is it mandatory to move to swift 2.3 or Swift 3 and build the app with Xcode 8?

Answer 1

Yes you can.

Even macOS Sierra will support Xcode 7.3 (unlike Xcode 6 on El Capitan), so you can choose to build your applications in Swift 2.2 or Swift 3.

For the App Store submission, the minimum Xcode version is 6.0. (October 2016)
