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 and GAI error. I receive the same error whether I am using CocoaPods or not. The location of the error is in the AppDelegate.swift here:

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

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

    // Optional: configure GAI options.
    let gai = GAI.sharedInstance()
    gai.trackUncaughtExceptions = true  // report uncaught exceptions

    return true
}

Nothing additional is able to be imported into the AppDelegate.swift(such as Google), just the standard UIKit.

I have been through many tutorials and other SO questions, all to no avail. I figure that there is some small thing I am missing, but cannot find it.

What I've done:

I have the .h files in my project, along with libGoogleAnalyticsServices.a, libsqlite3.0.tbd, libz.tbd, libsqlite3.tbd (all of which have been linked to library as well as CoreData and SystemConfiguration).

You can see the layout of all these files here:

and here:

I have created the -Bridging-Header.h and included these .h imports in it.

#import "GAI.h"
#import "GAIDictionaryBuilder.h"
#import "GAIEcommerceFields.h"
#import "GAIEcommerceProduct.h"
#import "GAIEcommerceProductAction.h"
#import "GAIEcommercePromotion.h"
#import "GAIFields.h"
#import "GAILogger.h"
#import "GAITrackedViewController.h"
#import "GAITracker.h"

The -Bridging-Header.h is linked in the Build Settings and I receive no errors with that. That is the main solution that I have found during my research, which hasn't helped me in this situation.

I have tried to start over from scratch twice with CocoaPods and without (I made a copy of my project before starting) and I received the same error each time.

Any help would certainly be appreciated. Thanks in advance.

Well, it looks like I was able to get it squared away.

There were several problems with all attempts on this.

Cocoapods had not installed correctly. I reinstalled and then had better success importing the correct files.
Doing it manually, as I posted above is not the best option.
After the Cocoapods re-install and starting over from a fresh copy of my project, I was able to import Google into my AppDelegate.swift.

Key points for those who may end up in the same boat I was in:

Be sure to add the correct directory for your -Bridging-Header.h. You can find this under Project - Build Settings - Swift Compiler Code Generation. Use this to easily target your header file $(SWIFT_MODULE_NAME)-Bridging-Header.h
In your -Bridging-Header.h, do not #import <Google/Analytics.h>, instead import the files individually. Here is an image of the files available to be imported.

When in doubt, reinstall Cocoapods
Do not trust Google tutorials to provide the most effective instruction and utilize the many SO posts on the topic.

I really hope this helps someone not spend 10 hours on the problem as I have.

I followed this including re-checking-out my project and everything thing is fine now. Hours upon hours, and it seems that cocoapods installed incorrectly or something (perhaps incorrectly set the build settings). From scratch I pod init, added the " pod 'Google/Analytics' " and "pod install"'d - created the bridging header, added all of the individual files (cut and pasted from initial question near the bottom) - pointed build settings to the bridging header - now import Google works in AppDelegate and the bridging header isn't complaining about being not found! — Chris Allinson, Feb 02 '17 at 03:00

Swift 4.0 and xcode 9.0.1 finally I resolved.

For me after 2 days I resolved.. Don't follow Google's old documentation says #import <Google/Analytics.h>

Go to Terminal type pod init
Reopen project as workspace obvious after pod workspace is created, open podfile. write pod 'GoogleAnalytics' in your pod file before target 'GoogleAnalytics' do
Go back to Terminal pod install you will find frameworks GAI.h and other files will be there under pods folder
Create Header.h file to your root. Don't add #import <Google/Analytics.h> instead import following individually in bridging header file

e.g. in bridging header file remove #import <Google/Analytics.h>

#import GAI.h
#import "GAITracker.h"
#import "GAIFields.h"
#import "GAIDictionaryBuilder.h"

Point your bridge under Build Settings for target Swift Compiler - General -> Objective-C Bridging Header. write Header.h of your bridging file name

Add code from google for swift to didFinishLaunchingWithOptions Don't forget to replace your tracking id from Google Analytics page

    guard let gai = GAI.sharedInstance() else {
        assert(false, "Google Analytics not configured correctly")
    }
    gai.tracker(withTrackingId: "YOUR_TRACKING_ID")
    // Optional: automatically report uncaught exceptions.
    gai.trackUncaughtExceptions = true

    // Optional: set Logger to VERBOSE for debug information.
    // Remove before app release.
    gai.logger.logLevel = .verbose;

Tada.... Run your project...

My error was use of unresolved identifier when i was using the singleton GAI.sharedInstance().

My steps to bring this to work were:

add pod 'Google/Analytics'
pod install
restart xcode
create a objc class in my project to get a bridging header
added #import "GAI.h" in to the bridging header file

everything works perfectly.

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

add the GoogleService-Info.plist file to the root of your project
add this to the podfile:
```
  pod 'Google/Analytics'
```
quit Xcode, run "pod install" in terminal and open Xcode again
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

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

  #ifndef Bridging_Header_h
  #define Bridging_Header_h
  #import <Google/Analytics.h> 
  #endif /* Bridging_Header_h */

add to AppDelegate:
```
import Google        
```

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.

The only way to make it work for me was downgrade Google Analytics pod version to 2.0.4.

pod 'Google/Analytics', '~> 2.0.4'
