How do I get the current version of my iOS project in code?

I would like to be able to get the current version of my iOS project/app as an `NSString` object without having to define a constant in a file somewhere. I don't want to change my version value in 2 places.

The value needs to be updated when I bump my version in the Project target summary.

**[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!
}

You can get the version and build numbers as follows:

let version = Bundle.main.object(forInfoDictionaryKey: "CFBundleShortVersionString") as! String
let build = Bundle.main.object(forInfoDictionaryKey: kCFBundleVersionKey as String) as! String

or in Objective-C

NSString * version = [[NSBundle mainBundle] objectForInfoDictionaryKey: @"CFBundleShortVersionString"];
NSString * build = [[NSBundle mainBundle] objectForInfoDictionaryKey: (NSString *)kCFBundleVersionKey];

I have the following methods in a category on `UIApplication`:


extension UIApplication {

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

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

static var versionBuild: String {
let version = appVersion, build = appBuild
return version == build ? "v\(version)" : "v\(version)(\(build))"
}
}

Here's the equivalent in Objective-C:

+ (NSString *) appVersion
{
return [[NSBundle mainBundle] objectForInfoDictionaryKey: @"CFBundleShortVersionString"];
}

+ (NSString *) build
{
return [[NSBundle mainBundle] objectForInfoDictionaryKey: (NSString *)kCFBundleVersionKey];
}

+ (NSString *) versionBuild
{
NSString * version = [self appVersion];
NSString * build = [self build];

NSString * versionBuild = [NSString stringWithFormat: @"v%@", version];

if (![version isEqualToString: build]) {
versionBuild = [NSString stringWithFormat: @"%@(%@)", versionBuild, build];
}

return versionBuild;
}

**Just for note**

To obtain localized value of any key you should use `CFBundleGetValueForInfoDictionaryKey(CFBundleGetMainBundle(), "CFBundleShortVersionString" as CFString)`

Here's what worked on **Xcode 8, Swift 3:**

let gAppVersion = Bundle.main.object(forInfoDictionaryKey: "CFBundleShortVersionString") ?? "0"
let gAppBuild = Bundle.main.object(forInfoDictionaryKey: "CFBundleVersion") ?? "0"

print("Version: \(gAppVersion)")
print("Build: \(gAppBuild)")

In Objective C:

1)For getting App version you have to use a:

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

2)For getting Build version you have to use a:

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

So heres a Swift version for both of these separately:


let versionNumber = NSBundle.mainBundle().objectForInfoDictionaryKey("CFBundleShortVersionString") as! String
let buildNumber = NSBundle.mainBundle().objectForInfoDictionaryKey("CFBundleVersion") as! String

An open source project of mine, [App Update Tracker][1], offers this functionality (and more) in the form of class methods:

- `+ (NSString *)getShortVersionString`
- `+ (NSString *)getLongVersionString`

You would use it like so:

#import "AppUpdateTracker.h"

NSLog(@"short version: %@", [AppUpdateTracker getShortVersionString]);
NSLog(@"long version: %@", [AppUpdateTracker getLongVersionString]);

In Swift, you can get bundle version by using:


let info:NSDictionary = NSBundle.mainBundle().infoDictionary!

let version:String = info.objectForKey("CFBundleShortVersionString") as! String

versionLabel.text = "Version:" + version
