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

7 Solutions Collect From Internet About “How do I get the current version of my iOS project in code?”

You can get the version and build numbers as follows:

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

    class func appVersion() -> String {
        return Bundle.main.object(forInfoDictionaryKey: "CFBundleShortVersionString") as! String
    }

    class func appBuild() -> String {
        return Bundle.main.object(forInfoDictionaryKey: kCFBundleVersionKey as String) as! String
    }

    class func 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;
}

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 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

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"]; 

An open source project of mine, App Update Tracker, 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]);

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

Just for note

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