Versions tracker for your iOS, macOS, and tvOS app

VersionTrackerSwift is a versions tracker for your iOS, macOS, and tvOS app is a version/builds tracker to know which version has been installed by a user.

Usage:

In your ApplicationDelegate, call the method track to track the current version:

// iOS / tvOS
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    VersionTracker.track()
    return true
}

// macOS
func applicationDidFinishLaunching(aNotification: NSNotification) {
    VersionTracker.track()
    return true        
}
Swift
Then, call whenever one of the following methods to get the data you need:

VersionTracker.shared.track() 
VersionTracker.shared.isFirstLaunchEver // Bool
VersionTracker.shared.isFirstVersionLaunch // Bool
VersionTracker.shared.isFirstBuildLaunch // Bool
VersionTracker.shared.versionHistory // [String]
VersionTracker.shared.buildHistory // [String]

VersionTracker.currentVersion // String
VersionTracker.currentBuild // String

Check out the examples and play with the version / build / number to have a concrete example.

How it works?

Each time you call the method track, the version and build are stored in NSUserDefaults if a new version / build is detected. Then, you can access to any information from the tracker.

The version and build number are the information you specify in your app’s Info.plist.
