Use of Unresolved Identifier 'GMSServices'

问题

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:

1. $ sudo gem install cocoapods

2. under "AreaCalculator" $ touch Podfile

3. in Podfile I put:

   source 'https://github.com/CocoaPods/Specs.git'
   platform :ios, '9.1'
   pod 'GoogleMaps'
   

4. $ pod install

   in the terminal:

   [!] Unable to load a specification for the plugin /Library/Ruby/Gems/2.0.0/gems/cocoapods-try-release-fix-0.1.2 Updating local specs repositories Analyzing dependencies Downloading dependencies Installing GoogleMaps (1.10.5) Generating Pods project Integrating client project

   [!] Please close any current Xcode sessions and use AreaCalculator.xcworkspace for this project from now on. Sending stats Pod installation complete! There is 1 dependency from the Podfile and 1 total pod installed.

5. 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:
   "AreaCalculator-Bridging-Header.h".

   • "#import GoogleMaps/GoogleMaps.h

6. Then I add "GoogleMaps.framework" in "Link Binary With Libraries". And both "GoogleMaps.framwork" and ""GoogleMaps.bundle" are in the Pods folder.

7. After all those done, in the AppDelegate.swift, I put:

   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]?) -> Bool {
           // Override point for customization after application launch.
           GMSServices.provideAPIKey(googleMapsApiKey)
           return true
       }
   }
   

However, the compiler showed me an error "Use of Unresolved Identifier 'GMSServices' ".

I have no idea where I did wrong? Anyone can help?

Thanks!

I have solved the problem by "import GoogleMaps" in the AppDelegate.swift.

Add this line in AppDelegate.m

#import "GoogleMaps/GoogleMaps.h"
