[Swift version: 5.2]

All iOS apps must store an app version number in their Info.plist file, but there’s no build-in way to get that as a string you can use in your code.

I have created one small extension to UIApplication that reads the Info.plist file and returns a version number automatically.

Here’s the code:

extension UIApplication {
    static var appVersion: String? {
        return Bundle.main.object(forInfoDictionaryKey: "CFBundleShortVersionString") as? String
    }
}

Inside Your Controller

@IBOutlet weak var tv_version: UILabel!
override func viewDidLoad() {
    super.viewDidLoad()
   
    //Display Version
    setUpCurrentVersion()
}


func setUpCurrentVersion(){
    tv_version.text = "v" + UIApplication.appVersion!
}
