--- id: react-native-ios title: Manually set up your React Native iOS App sidebar_label: React Native for iOS --- These instructions are aimed at people manually adding Flipper to a React Native 0.62+ app. This should only be necessary if you have an existing app that cannot be upgraded with the [React Native Upgrade tool](https://reactnative.dev/docs/upgrading). ## Dependencies Add this code to your `ios/Podfile`: ```ruby platform :ios, '9.0' def flipper_pods() flipperkit_version = '0.36.0' pod 'FlipperKit', '~>' + flipperkit_version, :configuration => 'Debug' pod 'FlipperKit/FlipperKitLayoutPlugin', '~>' + flipperkit_version, :configuration => 'Debug' pod 'FlipperKit/SKIOSNetworkPlugin', '~>' + flipperkit_version, :configuration => 'Debug' pod 'FlipperKit/FlipperKitUserDefaultsPlugin', '~>' + flipperkit_version, :configuration => 'Debug' pod 'FlipperKit/FlipperKitReactPlugin', '~>' + flipperkit_version, :configuration => 'Debug' end # Post Install processing for Flipper def flipper_post_install(installer) installer.pods_project.targets.each do |target| if target.name == 'YogaKit' target.build_configurations.each do |config| config.build_settings['SWIFT_VERSION'] = '4.1' end end end file_name = Dir.glob("*.xcodeproj")[0] app_project = Xcodeproj::Project.open(file_name) app_project.native_targets.each do |target| target.build_configurations.each do |config| cflags = config.build_settings['OTHER_CFLAGS'] || '$(inherited) ' unless cflags.include? '-DFB_SONARKIT_ENABLED=1' puts 'Adding -DFB_SONARKIT_ENABLED=1 in OTHER_CFLAGS...' cflags << '-DFB_SONARKIT_ENABLED=1' end config.build_settings['OTHER_CFLAGS'] = cflags end app_project.save end installer.pods_project.save end target 'your-app-name' do ... # Replace the existing yoga import with the following (adding modular_headers): pod 'Yoga', :path => '../node_modules/react-native/ReactCommon/yoga', :modular_headers => true ... use_native_modules! # For enabling Flipper. # Note that if you use_framework!, flipper will not work. # Disable these lines if you are doing use_framework! flipper_pods() post_install do |installer| flipper_post_install(installer) end end ``` Install the dependencies by running `cd ios && pod install`. You can now import and initialize Flipper in your AppDelegate. ## Initialization The code below enables the following integrations: - Layout Inspector - Network - Shared Preferences - Crash Reporter ```objective-c ... #if DEBUG #ifdef FB_SONARKIT_ENABLED #import #import #import #import #import #import #import #endif #endif @implementation AppDelegate - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { [self initializeFlipper:application]; ... } - (void) initializeFlipper:(UIApplication *)application { #if DEBUG #ifdef FB_SONARKIT_ENABLED FlipperClient *client = [FlipperClient sharedClient]; SKDescriptorMapper *layoutDescriptorMapper = [[SKDescriptorMapper alloc] initWithDefaults]; [client addPlugin: [[FlipperKitLayoutPlugin alloc] initWithRootNode: application withDescriptorMapper: layoutDescriptorMapper]]; [client addPlugin: [[FKUserDefaultsPlugin alloc] initWithSuiteName:nil]]; [client addPlugin: [FlipperKitReactPlugin new]]; [client addPlugin: [[FlipperKitNetworkPlugin alloc] initWithNetworkAdapter:[SKIOSNetworkAdapter new]]]; [client start]; #endif #endif } @end ``` ```swift ... #if DEBUG #if FB_SONARKIT_ENABLED import FlipperKit #endif #endif @UIApplicationMain class AppDelegate: UIResponder, UIApplicationDelegate { func application( _ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]? ) -> Bool { initializeFlipper(with: application) ... } private func initializeFlipper(with application: UIApplication) { #if DEBUG #if FB_SONARKIT_ENABLED let client = FlipperClient.shared() let layoutDescriptorMapper = SKDescriptorMapper(defaults: ()) FlipperKitLayoutComponentKitSupport.setUpWith(layoutDescriptorMapper) client?.add(FlipperKitLayoutPlugin(rootNode: application, with: layoutDescriptorMapper!)) client?.add(FKUserDefaultsPlugin(suiteName: nil)) client?.add(FlipperKitReactPlugin()) client?.add(FlipperKitNetworkPlugin(networkAdapter: SKIOSNetworkAdapter())) client?.add(FlipperReactPerformancePlugin.sharedInstance()) client?.start() #endif #endif } } ``` Lastly, open the Flipper desktop app, and run `yarn ios` in your terminal. ## Troubleshooting If you can't build your app after adding Flipper, you may need to configure the Swift compiler. To do so, adding an empty Swift file in your project is the easiest way. ## Further Steps To create your own plugins and integrate with Flipper using JavaScript, check out our [writing plugins for React Native](tutorial/react-native) tutorial!
