It's pretty much the same, except instead of using brackets, you use dots.

func applicationDidBecomeActive(application: UIApplication!) {    FBSDKAppEvents.activateApp()}func application(application: UIApplication!, didFinishLaunchingWithOptions launchOptions: NSDictionary!) -> Bool {    return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)}func application(application: UIApplication, openURL url: NSURL, sourceApplication: String, annotation: AnyObject?) -> Bool {    return FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: sourceApplication, annotation: annotation)}

LoginManager (custom login, see docs for default/button implementation)

contains custom code but you get the point

let facebookManager = LoginManager(loginBehavior: .systemAccount, defaultAudience: .everyone)func loginWithFacebook() {    self.facebookManager.logIn(HAAccountManager.shared.facebookPermissions, viewController: self) { (result) in        switch result {        case .failed(let error):            self.showAlert(forError: error as NSError)        case .cancelled:            print("FB login cancelled")        case .success(let grantedPermissions, let deniedPermissions, let accessToken):            if grantedPermissions.contains(Permission(name: "email")) == true {                ApiClient.shared.facebookSignIn(authToken: accessToken.authenticationToken, completion: { (err, user) in                    if err == nil {                        // success                    }                    else {                        self.showAlert(forError: err!)                    }                })            }            else {                self.showAlert(forError: HAError(title: String(format: String.somethingError, String.signIn), message: grantedPermissions.contains(Permission(name: "email")) == true ? String.noAccountFound : String.missingEmailForSignUp))            }        }    }}

Analytics

// custom exAppEventsLogger.log(AppEvent(name: "open_app", parameters: ["logged_in": NSNumber(value: HAAccountManager.shared.isUserLoggedIn())], valueToSum: nil))// purchase exAppEventsLogger.log(    AppEvent.purchased(        amount: Double(revenue),        currency: currency,        extraParameters: [            AppEventParameterName.contentId : orderId,            AppEventParameterName.itemCount : order.orderItems.count.nsNumber()        ]))

This has been depricated in iOS 10.

func application(application: UIApplication, openURL url: NSURL, sourceApplication: String, annotation: AnyObject?) -> Bool {

For Swift 3.0, you can use:

Swift 3.0

func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {    let isHandled = FBSDKApplicationDelegate.sharedInstance().application(app, open: url, sourceApplication: options[.sourceApplication] as! String!, annotation: options[.annotation])    return isHandled}
