private is still valid in Swift 3. You can read the difference between private and fileprivate here: https://cocoacasts.com/what-is-the-difference-between-private-and-fileprivate-in-swift-3/
Why you think, that should be changed? I think the reason why your XCode want to update swift code is that Swift Language Version is not defined in the project.

Well Xcode Says that is not updated to Swift 3.

You can create one blank ionic app , add the plugin and cordova build ios. You will see one log saying that is not updated to swift 3

Please try to do the same thing with your modifications. For me the same thing happens.
The ionic build ios displays the following message:
“Swift Language Version” (SWIFT_VERSION) is required to be configured correctly for targets which use Swift. Use the [Edit > Convert > To Current Swift Syntax…] menu to choose a Swift version or use the Build Settings editor to configure the build setting directly.
So somehow the SWIFT_VERSION flag needs to set up, to fix this.

I've added cordova-plugin-add-swift-support to fix this.
