Not opening on Xcode 9

[KatkayApps]

I have tried to open your project on Xcode 9. I was greeted with an alert telling me that this was written in Swift 2 and that Xcode was unable to open it. The warning told me to open it on Xcode 8.x and convert it from Swift 2 to 3 then open it on Xcode 9 and convert from Swift 3 to 5. It is amateur hour from Apple.

Obviously, Xcode 8.x failed to open the project.
