I'm not sure what you mean with Swift - obj-c. You can still build apps with Objective-C in the Xcode 8 version and you can also open old Objective-C code with Xcode 8. The only thing that happens, is that Xcode will ask you to what new device the storyboard needs to change.

If you want to work with Swift 2.2 for some reason and you don't want to change that code to Swift 3.0, you can download the old Xcode 7.3.1 from the Apple site here and work with your code that is still in Swift 2.2.

I would not recommend to continue to work with Swift 1.2.
