How to fix Bool Return error with Parse?

Question

When I compile the code parse asks to put in appdelegate.Swift appears "Return in Function to Return Bool" but when I enter Return true, there are more than 30 errors and still not working, follow the appdelegate code:

import UIKit

import Parse

import Bolts

@UIApplicationMain

class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

        Parse.enableLocalDatastore()

        // Initialize Parse.

        Parse.setApplicationId("xxxxxxxxxxxxxxxxxxxj",

        clientKey: "xxxxxxxxxxxxxx")

        PFAnalytics.trackAppOpenedWithLaunchOptions(launchOptions)

        return true

}
