Use of unresolved identifier GGLContext and GAI

Question

I am having a bit of trouble. I am attempting to install Google Analytics into an app and am consistently getting the use of unresolved identifier GGLContext a

Answer 1

This works for swift 2.3, swift 3.0 and swift 4:

1. add the GoogleService-Info.plist file to the root of your project

2. add this to the podfile:

     pod 'Google/Analytics'
   

3. quit Xcode, run "pod install" in terminal and open Xcode again

4. create a header file in the project root, named Bridging-Header.h, under build settings make sure the bridging header is defined like in the picture

5. make sure your Bridging-Header.h looks like this:

     #ifndef Bridging_Header_h
     #define Bridging_Header_h
     #import  
     #endif /* Bridging_Header_h */
   

6. add to AppDelegate:

   import Google        
   

7. add this code to AppDelegate in the didFinishLaunchingWithOptions method:

   // Configure tracker from GoogleService-Info.plist.
   var configureError: NSError?
   GGLContext.sharedInstance().configureWithError(&configureError)
   
   assert(configureError == nil, "Error configuring Google services:\(configureError)")
   
   // Optional: configure GAI options.
   guard let gai = GAI.sharedInstance() else {
       assert(false, "Google Analytics not configured correctly")
   }
   gai.trackUncaughtExceptions = true  // report uncaught exceptions
   gai.logger.logLevel = GAILogLevel.Verbose  // remove before app release
   

If there are errors, deleting DerivedData and cleaning the project can help.
