How to use both google+ and facebook login in same appdelegate.swift
<p>My app use google+ signin and in my appdelegate.swift i have:</p>

<pre><code>func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -&gt; Bool {
    // Override point for customization after application launch.

    var configureError: NSError?
    GGLContext.sharedInstance().configureWithError(&amp;configureError)
    assert(configureError == nil, "Error configuring Google services: \(configureError)")

    GIDSignIn.sharedInstance().delegate = self

    return true

}


func application(application: UIApplication,
    openURL url: NSURL, sourceApplication: String?, annotation: AnyObject) -&gt; Bool {
        return GIDSignIn.sharedInstance().handleURL(url,
            sourceApplication: sourceApplication,
            annotation: annotation)
}
</code></pre>

<p>Now i would like to insert also facebook login, but i have to add in appdelegate.swift this code:</p>

<pre><code>func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -&gt; Bool {
    // Override point for customization after application launch.
    return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
}

func application(application: UIApplication,
    openURL url: NSURL,
    sourceApplication: String?,
    annotation: AnyObject?) -&gt; Bool {
        return FBSDKApplicationDelegate.sharedInstance().application(
            application,
            openURL: url,
            sourceApplication: sourceApplication,
            annotation: annotation)
}
</code></pre>

<p>But this return error because the functions 'application' already exist, how can I perform both google+ and facebook same appdelegate.swift
Thank you.</p>
