VersionTrackerSwift is a versions / builds tracker to know which version has been installed by a user.

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        
}

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.

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.

Add the following line in your Podfile:

pod 'VersionTrackerSwift'
