Summary: When upgrading to RN 0.68, the upgrade helper removes the old Flipper initialization in favor of importing `RCTAppSetupUtils` which abstracts the Flipper initialization. To be consistent, we should show in the docs that for 0.68 the preferred way is to import `RCTAppSetupUtils` in the AppDelegate. ## Changelog - RN iOS setup docs has been updated to include the new way to initialize Flipper on React Native 0.68.
