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

I know this has already been answered but personally I think this is a little cleaner:

Swift 3.0:

 if let version = Bundle.main.infoDictionary?["CFBundleShortVersionString"] as? String {
    self.labelVersion.text = version
}

Swift <2.3

if let version = NSBundle.mainBundle().infoDictionary?["CFBundleShortVersionString"] as? String {
    self.labelVersion.text = version
}

This way, the if let version takes care of the conditional processing (setting the label text in my case) and if infoDictionary or CFBundleShortVersionString are nil the optional unwrapping will cause the code to be skipped.
