Firebase- Could not locate configuration file: 'GoogleService-Info.plist'
<p>I have downloaded it already and added it to my Xcode Project I did copy items if needed as well .. I do not understand why I am still getting this error. I have FIRApp.configure() in my app delegate... Any tips? Thank you in advance. </p>

<pre><code> func application(application: UIApplication,
                         didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?)
            -&gt; Bool {
                UINavigationBar.appearance().tintColor = UIColor.greenColor()
                UIApplication.sharedApplication().statusBarStyle = .LightContent

                FIRApp.configure()
                return true
        }
</code></pre>
