✏️ Description

Update our codebase to support legacy ios architecture in iOS.

Testing

Building the iOS version of this app in legacy arch should work

• open example>ios>podfile
  • change ENV['RCT_NEW_ARCH_ENABLED'] = '1' to ENV['RCT_NEW_ARCH_ENABLED'] = '0'
• in example>ios, run the following:
  • bundle exec pod deintegrate
  • rm -rf ~/Library/Developer/Xcode/DerivedData Pods Podfile.lock build ../Gemfile.lock
  • bundle install
  • bundle exec pod install
• in example run:
  • watchman watch-del-all
  • yarn start --reset-cache
• build the ios app

The app should build and load correctly

Pull Request Overview

This PR adds backwards compatibility to support the legacy iOS architecture in React Native. The changes enable the module to work with both the new Fabric architecture and the legacy architecture by using conditional compilation directives.

• Uses RCT_NEW_ARCH_ENABLED preprocessor conditionals to separate new and legacy architecture code paths
• Adds legacy architecture method exports using RCT_EXPORT_METHOD macros
• Updates the header to conditionally import different React Native modules and implement different protocols

Reviewed Changes

File	Description
ios/RNIterableAPI/RNIterableAPI.h	Conditionally imports different React Native modules and implements either NativeRNIterableAPISpec or RCTBridgeModule protocol based on architecture
ios/RNIterableAPI/RNIterableAPI.mm	Adds conditional compilation to separate new architecture functions from legacy RCT_EXPORT_METHOD implementations for backwards compatibility

The comment '// MARK: - RNIterableAPI functions exposed to JS' should be moved inside the #if RCT_NEW_ARCH_ENABLED block since these functions are specific to the new architecture.

Works as expected. Just run into the error I brought up. But, seems like a separate issue
