var tracker = GAI.sharedInstance().defaultTracker
tracker.set(kGAIScreenName, value: "rootPlayView")

var builder = GAIDictionaryBuilder.createScreenView()
tracker.send(builder.build() as [NSObject : AnyObject])

Then i got an error like this

how can i fix this?

type conversion

Swift 3

Screen Track

let tracker = GAI.sharedInstance().defaultTracker
tracker.set(kGAIScreenName, value: "Home")
tracker.send(GAIDictionaryBuilder.createScreenView().build() as [AnyHashable : Any])

Objective-C

id<GAITracker> tracker = [[GAI sharedInstance] defaultTracker];
// Set the screen name on the tracker so that it is used in all hits sent from this screen.
[tracker set:kGAIScreenName value:@"Home"];
[tracker send:[[GAIDictionaryBuilder createScreenView]  build]];

Automatic Screen Tracking

Swift 3

override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)
    self!.screenName = "About Screen"
}

Objective-C

- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];
    self.screenName = @"About Screen";
}

event Track

Swift 3

let tracker = GAI.sharedInstance().defaultTracker

tracker!.send(GAIDictionaryBuilder.createEventWithCategory("ui_action", action: "button_press", label: "menuButton", play: nil).build())

Objective-C

id<GAITracker> tracker = [[GAI sharedInstance] defaultTracker];

[tracker send:[[GAIDictionaryBuilder createEventWithCategory:@"ui_action"     // Event category (required)
    action:@"button_press"  // Event action (required)
    label:@"play"           
    value:nil] build]];

or use

weak var tracker = GAI.sharedInstance().defaultTracker
// Set screen name on the tracker to be sent with all hits.
 tracker!.set(kGAIScreenName, value: "Home Screen")
// Send a screen view for "Home Screen".
// [tracker send:[[GAIDictionaryBuilder createAppView] build]];   

// Previous V3 SDK versions.
tracker!.send(GAIDictionaryBuilder.createScreenView().build())

// SDK Version 3.08 and up.
// This event will also be sent with &cd=Home%20Screen.
tracker!.send(GAIDictionaryBuilder.createEventWithCategory("UX", action: "touch", label: "menuButton", value: nil).build())
// Clear the screen name field when we're done.
tracker!.set(kGAIScreenName, value: nil)

for more information see this

example

try this

var builder = GAIDictionaryBuilder.createScreenView().build() as! [NSObject : AnyObject]
tracker.send(builder)

for screen track

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

for event Track

let tracker = GAI.sharedInstance().defaultTracker
let builder: NSObject = GAIDictionaryBuilder.createEventWithCategory(
            "xxxx",
            action: "buttonclicked",
            label: "you pressed xxx button",
            value: nil).build()
tracker.send(builder as! [NSObject : AnyObject])

tracker in this case is an optional and requires unwrapping. This worked for me: `if let tracker = GAI.sharedInstance().defaultTracker{ tracker.set(kGAIDescription, value: "rootPlayView") let builder: NSObject = GAIDictionaryBuilder.createScreenView().build() tracker.send(builder as! [NSObject : AnyObject]) }` — Fuad Kamal, Sep 16 '16 at 00:58
@FuadKamal- can you update the answer, it is useful for others — Anbu.Karthik, Sep 16 '16 at 04:18
This answer needs update. This is not Swift 3 version. At least not current one. — funct7, Oct 10 '16 at 05:48

This answer has been updated for Swift 3

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]!)

OR...

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

For GA 3.17.0 use:

let tracker = GAI.sharedInstance().defaultTracker
let builder = GAIDictionaryBuilder.createEvent(withCategory: category,
                                                     action: action,
                                                      label: nil,
                                                      value: nil).build()
tracker?.send(builder as [NSObject : AnyObject]!)

Note the ! at the end of [NSObject: AnyObject]!.

Small follow up on the amazing answers, in swift 3, the method is

let builder:NSObject = GAIDictionaryBuilder.createEvent(withCategory: category, action: eventName, label: label, value: nil).build()
