 3. Go to `node_modules` ➜ `react-native-google-analytics-bridge` ➜ `ios` ➜ `RCTGoogleAnalyticsBridge` and add the `RCTGoogleAnalyticsBridge.xcodeproj` file.
 4. Add libRCTGoogleAnalyticsBridge.a from the linked project to your project properties ➜ "Build Phases" ➜ "Link Binary With Libraries"
 5. Next you will have to link a few more SDK framework/libraries which are required by GA (if you do not already have them linked.) Under the same "Link Binary With Libraries", click the + and add the following:
   1. CoreData.framework
   2. SystemConfiguration.framework
   3. libz.tbd
   4. libsqlite3.0.tbd

-  **Optional**: If you plan on using the advertising identifier (IDFA), then you also need to add AdSupport.framework
 7. Under your project properties ➜ "Info", add a new line with the following:
   1. Key: GAITrackingId
   2. Type: String
   3. Value: UA-12345-1 (in other words, your own tracking id).
+8. **Optional step**: If you plan on using the advertising identifier (IDFA), then you need to do two things:
+  1. Add AdSupport.framework under "Link Binary With Libraries". (As with the other frameworks in step 5).
+  2. Go to Xcode ➜ `Libraries` ➜ `RCTGoogleAnalyticsBridge.xcodeproj` ➜ right-click `google-analytics-lib`. Here you need to `Add files to ..`, and add `libAdIdAccess.a` from the `google-analytics-lib` directory. This directory is located in the same directory as in step 3.
