Setup:

$ ( cd react-native && yarn install )
$ ( cd react-native/ios && pod install )

Running:

$ make shadow
$ make bundler
$ make ios

Note: The first time you run the simulator, you must press Command-D and then click "Disable Fast Refresh". This will disable react-native's automatic fast-refreshing. Instead, we are manually calling helix.experimental.refresh/refresh! after shadow-cljs recompiles/reloads.
