Issue with Google Analytics in Swift 2 or 3

Question

I have a problem with Swift 2 (Swift 3) and Google Analytics.

This is the line with the problem:

tracker.send(GAIDictionaryBuilder.createScreenView(

This is a solution I came up with.. Maybe it could help some of you. It's a struct you need to instantiate in every UIViewController, but it helps with the boilerplate.

import UIKit

struct Analytics {
    fileprivate let viewController: UIViewController
    fileprivate let tracker = GAI.sharedInstance().defaultTracker

    init (forScreen viewController: UIViewController) {
        self.viewController = viewController
    }

    func startTracking () {
        let screenView = GAIDictionaryBuilder.createScreenView().build() as NSDictionary
        guard
            let tracker = tracker,
            let build = screenView as? [AnyHashable: Any]
        else { return }

        tracker.set(kGAIScreenName, value: String(describing: viewController))
        tracker.send(build)
    }
}

class HomeViewController: UIViewController {

    lazy var analytics: Analytics = {
        return Analytics(forScreen: self)
    }()

    override func viewDidLoad() {
        super.viewDidLoad()
    }

    override func viewWillAppear() {
        super.viewWillAppear()
        analytics.startTracking()
    }
}
