title: Use of Unresolved Identifier 'GMSServices'
body: <p>I am using Xcode 7.1 and the deployment target is iOS 9.1. The app is "AreaCalculator" and it was written in Swift. I did following to set up the framework and import the map:</p>
  
  <ol>
  <li><p>$ sudo gem install cocoapods</p></li>
  <li><p>under "AreaCalculator" $ touch Podfile</p></li>
  <li><p>in Podfile I put: </p>
  
  <pre><code>source 'https://github.com/CocoaPods/Specs.git'
  platform :ios, '9.1'
  pod 'GoogleMaps'
  </code></pre></li>
  <li><p>$ pod install</p>
  
  <p>in the terminal:</p>
  
  <p>[!] Unable to load a specification for the plugin        <code>/Library/Ruby/Gems/2.0.0/gems/cocoapods-try-release-fix-0.1.2</code>

  <p>[!] Please close any current Xcode sessions and use  <code>AreaCalculator.xcworkspace</code> for this project from now on.

  pod installed.</p></li>
  <li><p>After that, I selected the AreaCalculator folder in the Navigator
  and    select File\New\File…, then choose the iOS\Source\Objective-C
  File template and created a Bridging file:<br>
  "AreaCalculator-Bridging-Header.h".</p>
  
  <ul>
  <li>"#import GoogleMaps/GoogleMaps.h</li>
  </ul></li>
  <li><p>Then I add "GoogleMaps.framework" in "Link Binary With Libraries".
  And both "GoogleMaps.framwork" and ""GoogleMaps.bundle" are in the
  Pods folder.</p></li>
  <li><p>After all those done, in the AppDelegate.swift, I put:</p>
  
  <pre><code>import UIKit
  
  @UIApplicationMain
  class AppDelegate: UIResponder, UIApplicationDelegate {
  
      var window: UIWindow?
      let googleMapsApiKey = "MY_GOOGLE_IOS_API_KEY"
  
      func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -&gt; Bool {
          // Override point for customization after application launch.
          GMSServices.provideAPIKey(googleMapsApiKey)
          return true
      }
  }
  </code></pre></li>
  </ol>
  
  <p>However, the compiler showed me an error "Use of Unresolved Identifier 'GMSServices' ".</p>
  
  <p>I have no idea where I did wrong? Anyone can help?</p>
  
  <p>Thanks!</p>
