Getting Version and Build Info 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 Build.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.

Answer 3

For the final release of Xcode 6 use

NSBundle.mainBundle().infoDictionary?["CFBundleVersion"] as? String

The "?" character after infoDictionary is important here

Answer 4

Here is simple way to get Build and version.

For Swift 4.X

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

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

For Objective C

NSString *build = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleVersion"];

NSString * currentVersion = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"];

Let me know if any issue. This is working for me.

Answer 5

Swifty way for AppName, AppVersion and BuildNumber...

if let dict = NSBundle.mainBundle().infoDictionary {
   if let version = dict["CFBundleShortVersionString"] as? String,
       let bundleVersion = dict["CFBundleVersion"] as? String,
       let appName = dict["CFBundleName"] as? String {
           return "You're using \(appName) v\(version) (Build \(bundleVersion))."
   }
}

Answer 6

Swift 5.0

I created a wrapper for Swift 5 to get some app related strings at one place in all my apps, called AppInfo.

struct AppInfo {

var appName : String {
    return readFromInfoPlist(withKey: "CFBundleName") ?? "(unknown app name)"
}

var version : String {
    return readFromInfoPlist(withKey: "CFBundleShortVersionString") ?? "(unknown app version)"
}

var build : String {
    return readFromInfoPlist(withKey: "CFBundleVersion") ?? "(unknown build number)"
}

var minimumOSVersion : String {
    return readFromInfoPlist(withKey: "MinimumOSVersion") ?? "(unknown minimum OSVersion)"
}

var copyrightNotice : String {
    return readFromInfoPlist(withKey: "NSHumanReadableCopyright") ?? "(unknown copyright notice)"
}

var bundleIdentifier : String {
    return readFromInfoPlist(withKey: "CFBundleIdentifier") ?? "(unknown bundle identifier)"
}

var developer : String { return "my awesome name" }

// lets hold a reference to the Info.plist of the app as Dictionary
private let infoPlistDictionary = Bundle.main.infoDictionary

/// Retrieves and returns associated values (of Type String) from info.Plist of the app.
private func readFromInfoPlist(withKey key: String) -> String? {
    return infoPlistDictionary?[key] as? String
     }
}

You can use it like so:

print("The apps name = \(AppInfo.appname)")

Answer 7

In swift, I would make it as extension for UIApplication, like this:

extension UIApplication {

    func applicationVersion() -> String {

        return NSBundle.mainBundle().objectForInfoDictionaryKey("CFBundleShortVersionString") as! String
    }

    func applicationBuild() -> String {

        return NSBundle.mainBundle().objectForInfoDictionaryKey(kCFBundleVersionKey as String) as! String
    }

    func versionBuild() -> String {

        let version = self.applicationVersion()
        let build = self.applicationBuild()

        return "v\(version)(\(build))"
    }
}

Then you can just use following to get everything you need:

let version = UIApplication.sharedApplication.applicationVersion() // 1
let build = UIApplication.sharedApplication.applicationBuild() // 80
let both = UIApplication.sharedApplication.versionBuild() // 1(80)

Answer 8

//Returns app's version number

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

//Return app's build number

public static var appBuild: String? {
    return Bundle.main.object(forInfoDictionaryKey: kCFBundleVersionKey as String) as? String
}

Answer 9

This code works for Swift 3, Xcode 8:

let version = Bundle.main.object(forInfoDictionaryKey: "CFBundleShortVersionString") ?? "0"
let build = Bundle.main.object(forInfoDictionaryKey: "CFBundleVersion") ?? "0"

Answer 10

For Swift 3,Replace NSBundle with Bundle and mainBundle is replaced simply by main.

let AppVersion = Bundle.main.infoDictionary!["CFBundleVersion"] as! String

Answer 11

[Update: Xcode 6.3.1] I tried all of the above and none of these work in Xcode 6.3.1 but I found that this does:

(NSBundle.mainBundle().infoDictionary?["CFBundleVersion"] as? String)!

Answer 12

Another option is to define in the AppDelegate the variables:

var applicationVersion:String {
    return NSBundle.mainBundle().objectForInfoDictionaryKey("CFBundleShortVersionString") as! String
}
var applicationBuild:String  {
    return NSBundle.mainBundle().objectForInfoDictionaryKey(kCFBundleVersionKey as String) as! String
}
var versionBuild:String  {
    let version = self.applicationVersion
    let build = self.applicationBuild
    return "version:\(version) build:(\(build))"
}

that can be referenced as variables in the AppDelegate

Answer 13

Swift 3 :

let textVersion
 = Bundle.main.infoDictionary?["CFBundleVersion"] as? String

Answer 14

SWIFT 3 Version

if let infoPath = Bundle.main.path(forResource: "Info.plist", ofType: nil),
        let infoAttr = try? FileManager.default.attributesOfItem(atPath: infoPath),
        let infoDate = infoAttr[.creationDate] as? Date
{
    return infoDate
}
return Date()

Answer 15

To have result for framework you can use

let version = Bundle(for: type(of: self)).infoDictionary?["CFBundleShortVersionString"] as? String

or in tests

let version = Bundle(for: <SomeClass>.self).infoDictionary?["CFBundleShortVersionString"] as? String
