Often you need to extract version and build information, e.g. to display in an info-box. This short code snippet extracts this information for you and sets an appropriate label.

// Get version info and set version label
let dictionary = Bundle.main.infoDictionary!
let version = dictionary["CFBundleShortVersionString"] as! String
let build = dictionary["CFBundleVersion"] as! String
self.versionLabel.text = "Version \(version) Build \(build)"
