Getting version and build information with Swift

Question

I am attempting to gain access to the main NSBundle to retrieve version and build information. Thing is, I want to try it in Swift, I know how to retrieve it in Objective-C with:

text = [NSBundle.mainBundle.infoDictionary objectForKey:@"CFBundleVersion"]; 

Yet I don't know where to start with Swift, I have attempted to write it in the new syntax with no avail.

Answer 1

What was wrong with the Swift syntax? This seems to work:

if let text = Bundle.main.infoDictionary?["CFBundleVersion"] as? String {     print(text) } 

Answer 2

Swift 3/4 Version

func version() -> String {     let dictionary = Bundle.main.infoDictionary!     let version = dictionary["CFBundleShortVersionString"] as! String     let build = dictionary["CFBundleVersion"] as! String     return "\(version) build \(build)" }

Swift 2.x Version

func version() -> String {     let dictionary = NSBundle.mainBundle().infoDictionary!     let version = dictionary["CFBundleShortVersionString"] as String     let build = dictionary["CFBundleVersion"] as String     return "\(version) build \(build)" } 

as seen here.
