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

Answer 1

Having looked at the documentation, I believe that the following is cleaner:

let version = 
NSBundle.mainBundle().objectForInfoDictionaryKey("CFBundleShortVersionString") 
as? String

Source: "Use of this method is preferred over other access methods because it returns the localized value of a key when one is available."
