I have been looking to use Flipper for some time, but all of my team's dependencies are installed via Swift Package Manager, and so far Flipper is one of only 2 dependencies we have been looking to use that do not support it (the other being the Firebase SDK, which is currently working on SPM support).
The only information I've found for SPM support for Flipper is this old issue: #187 , which received very little response at the time.
Over the past few years SPM has become more and more the first class dependency manager for iOS, and it's generally expected that all libraries/tools support it.
Update RN iOS setup to include RN 0.68 new Flipper initialization
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.
RN iOS setup docs has been updated to include the new way to initialize Flipper on React Native 0.68.
