How do I get the App version and build number using Swift?

SWIFT 4

//First get the nsObject by defining as an optional AnyObject

let nsObject: AnyObject? = Bundle.main.infoDictionary?["CFBundleShortVersionString"] as AnyObject 

//Then just cast the object as a String, but be careful, you may want to double check for nil

let version = nsObject as! String 

For Swift 2.0

//First get the nsObject by defining as an optional anyObject let nsObject: AnyObject? = NSBundle.mainBundle().infoDictionary!["CFBundleShortVersionString"] let version = nsObject as! String 

if let version = Bundle.main.infoDictionary?["CFBundleShortVersionString"] as? String { lblVersion.text = "Version \(version)" } 

for anyone interested, there's a nice and neat library called SwifterSwift available at github and also fully documented for every version of swift (see swifterswift.com).

using this library, reading app version and build number would be as easy as this:

import SwifterSwift let buildNumber = UIApplication.shared.buildNumber let version = UIApplication.shared.version
