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

Swift 4

func getAppVersion() -> String {
    return "\(Bundle.main.infoDictionary!["CFBundleShortVersionString"] ?? "")"
}

Bundle.main.infoDictionary!["CFBundleShortVersionString"]

Swift old syntax

let appVer: AnyObject? = NSBundle.mainBundle().infoDictionary!["CFBundleShortVersionString"]
