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

Question

I have an IOS app with an Azure back-end, and would like to log certain events, like logins and which versions of the app users are running.

How can I return the ver

Answer 1

Simple utility function to return App version as Int

func getAppVersion() -> Int {

        if let appVersion = Bundle.main.infoDictionary?["CFBundleShortVersionString"] as? String {

            let appVersionClean = appVersion.replacingOccurrences(of: ".", with: "", options: NSString.CompareOptions.literal, range:nil)

            if let appVersionNum = Int(appVersionClean) {
                return appVersionNum
            }
        }
        return 0
    }

Answer 2

For Swift 4.0

let version = Bundle.main.infoDictionary!["CFBundleShortVersionString"]!
let build = Bundle.main.infoDictionary!["CFBundleVersion"]!

Answer 3

For Swift 5:

func getAppCurrentVersionNumber() -> String {
    let nsObject: AnyObject? = Bundle.main.infoDictionary!["CFBundleShortVersionString"] as AnyObject?
    return nsObject as! String
}

Answer 4

You can now use a constant for this, rather than having to use stringly-typed code like before, which makes things even more convenient.

var appVersion: String {
    return Bundle.main.infoDictionary![kCFBundleVersionKey as String] as! String
}

Answer 5

Bundle+Extension.swift (SwiftUI, Swift 5, Xcode 11)

I combined ideas from a few answers, and extended a bit:

• a SwiftUI example
• Displays a warning triangle emoticon (rather than crashing the app) if the key is missing from the Info.plist

import Foundation

extension Bundle {
    
    public var appVersionShort: String? {
        if let result = infoDictionary?["CFBundleShortVersionString"] as? String {
            return result
        } else {
            return "⚠️"
        }
    }
    public var appVersionLong: String? {
        if let result = infoDictionary?["CFBundleVersion"] as? String {
            return result
        } else {
            return "⚠️"
        }
    }
    public var appName: String? {
        if let result = infoDictionary?["CFBundleName"] as? String {
            return result
        } else {
            return "⚠️"
        }
    }
}

SwiftUI example use

VStack {

     Text("Version: \(Bundle.main.appVersionShort!) (\(Bundle.main.appVersionLong!))")
                    .font(.subheadline)
                    .frame(maxWidth: .infinity, maxHeight: .infinity)
}

Answer 6

I also know this has already been answered but I wrapped up the previous answers:

(*)Updated for extensions

extension Bundle {
    var releaseVersionNumber: String? {
        return infoDictionary?["CFBundleShortVersionString"] as? String
    }
    var buildVersionNumber: String? {
        return infoDictionary?["CFBundleVersion"] as? String
    }
    var releaseVersionNumberPretty: String {
        return "v\(releaseVersionNumber ?? "1.0.0")"
    }
}

Usage:

someLabel.text = Bundle.main.releaseVersionNumberPretty

@Deprecated: Old answers

Swift 3.1:

class func getVersion() -> String {
    guard let version = Bundle.main.infoDictionary?["CFBundleShortVersionString"] as? String else {
        return "no version info"
    }
    return version
}

For older versions:

class func getVersion() -> String {
    if let version = NSBundle.mainBundle().infoDictionary?["CFBundleShortVersionString"] as? String {
        return version
    }
    return "no version info"
}

So if you want to set label text or want to use somewhere else;

self.labelVersion.text = getVersion()
