UIButton Event Tracking Google Analytics (Swift)

Swift 3: You should use "[AnyHashable: Any]" instead of [NSObject: AnyObject].

Source: https://developer.apple.com/swift/blog/?id=39

guard let tracker = GAI.sharedInstance().defaultTracker else {return}
let eventTracker: NSObject = GAIDictionaryBuilder.createEvent(
    withCategory: YOUR_CATEGORY_NAME,
    action: YOUR_ACTION_NAME,
    label: YOUR_LABEL_NAME,
    value: nil).build()
tracker.send(eventTracker as! [AnyHashable: Any])

For Swift 5.

1.You should add GoogleService-Info.plist file in your project (see Google docs).

2.You should add this property in your Info.plist file:

<key>GoogleAnalytics</key>
<dict>
    <key>TRACKING_ID</key>
    <string>"put_your_tracking_id_here"</string>
</dict>

3.In AppDelegate class, in the didFinishLaunchingWithOptions method:

// GAI
    if let gai = GAI.sharedInstance(),
        let gaConfigValues = Bundle.main.infoDictionary?["GoogleAnalytics"] as? [String: String],
        let trackingId = gaConfigValues["TRACKING_ID"]
    {
        gai.logger.logLevel = .error
        gai.trackUncaughtExceptions = false
        gai.tracker(withTrackingId: trackingId)
    } else {
        assertionFailure("Google Analytics not configured correctly")
    }

4.In your ViewController, in the viewDidLoad metod (for example):

// GAI
    let tracker = GAI.sharedInstance().defaultTracker
    tracker?.set(kGAIScreenName, value: "Your_mark_name")
    let eventTracker: NSObject = GAIDictionaryBuilder.createScreenView().build()
    tracker?.send(eventTracker as! [NSObject : AnyObject])

5.After what you should drink your beer ;)

For Swift 3

let tracker = GAI.sharedInstance().defaultTracker
tracker.set(kGAIDescription, value: "ScreenViewName")
let eventTracker: NSObject = GAIDictionaryBuilder.createScreenView().build()
tracker.send(eventTracker as! [NSObject : AnyObject])

OR...

let tracker = GAI.sharedInstance().defaultTracker
let eventTracker: NSObject = GAIDictionaryBuilder.createEvent( 
            withCategory: "SomeCategory",
            action: "SomeAction",
            label: "SomeLabel",
            value: nil).build()
tracker.send(eventTracker as [NSObject : AnyObject]!)

Since Swift 1.2 is released, you have to cast GAIDictionaryBuilder as [NSObject : AnyObject]

See this post on StackOverflow

Google Analytics not working with Swift 1.2 and Xcode 6.3

There is the solution for your issue

@IBAction func startGame1(sender: AnyObject) {

        var tracker = GAI.sharedInstance().defaultTracker

        tracker.send(GAIDictionaryBuilder.createEventWithCategory("Game 1", action: "Start Pressed", label: "Start Timer One", value: nil).build() as [NSObject : AnyObject]) 
    }

Hope it helps!
