In this post we will learn how to fetch and show the iOS build and version number
Step 1 − Open Xcode → New Project → Single View Application → Let’s name it “ShowBuildAndVersion”
Step 2 − Open Main.storyboard and add two labels as shown below.
Step 3 − Attach @IBOutLets for the two labels
@IBOutlet weak var buildLabel: UILabel! @IBOutlet weak var versionLabel: UILabel!
Step 4 − Change the build and version from project settings.
Step 5 − In viewDidLoad of ViewController get the build and version number for infoDictionary of main bundle. Show it on the corresponding labels.
override func viewDidLoad() {
super.viewDidLoad()
if let version = Bundle.main.infoDictionary?["CFBundleShortVersionString"] as? String {
versionLabel.text = "Version: \(version)"
}
if let build = Bundle.main.infoDictionary?["CFBundleVersion"] as? String {
buildLabel.text = "Build: \(build)"
}
}The infoDictionary in main bundle contains these values, with ‘CFBundleShortVersionString’ and ‘CFBundleVersion’ keys.
We can refer these keys to get the version and build number respectively
Step 6 − Run the project, you should see the build and version number.
