Also add `RNFBApp` pods inside your target. ```ruby platform :ios, '9.0' //... target 'yourApp' do //... pod 'RNFBApp', :path => '../node_modules/@react-native-firebase/app/ios' end ``` Run `pod install` > You need to use the `ios/[YOUR APP NAME].xcworkspace` instead of the `ios/[YOUR APP NAME].xcproj` file from now on. #### Add App to AppDelegate.m **`ios/{yourApp}/AppDelegate.m`** A) At the top of the file: ```objectivec #import ``` B) At the beginning of the `didFinishLaunchingWithOptions:(NSDictionary *)launchOptions` method add the following line: ```objectivec [FIRApp configure]; ```
