How do I get the App version and build number using Swift?

Question

I have an IOS app with an Azure back-end, and would like to log certain events, like logins and which versions of the app users are running.

How can I return the ver

For Swift 3.0 NSBundle doesn't work, Following code works perfectly.

let versionNumberString =
      Bundle.main.object(forInfoDictionaryKey: "CFBundleShortVersionString")
          as! String

and for just the build number, it is:

let buildNumberString =
      Bundle.main.object(forInfoDictionaryKey: "CFBundleVersion")
          as! String

Confusingly 'CFBundleVersion' is the build number as entered in Xcode on General->Identity.
