Doesn't work with new bridgeless architecture on 0.76.0

[andrewzey]

Describe the bug
Because the new react-native architecture lazy loads modules by default, require('react-native').NativeModules is an empty object at app startup time. Search for "Lazy module loading by default" in https://reactnative.dev/blog/2024/10/23/the-new-architecture-is-here

To Reproduce
Load the app on React Native 0.76.0 and observe that all functions expected on AppleHealthKit are undefined.

Expected behavior
All functions on AppleHealthKit are should be defined at access time.

Workaround Confirmed to Work
Per this user's helpful comment (facebook/react-native#29228 (comment)), this workaround fixes the issue for MY app which only uses a handful of functions from react-native-health. This is far from a global solution though. I'm using yarn so I'm able to simply do a yarn patch react-native-health to be unblocked with this change:

index.js

import { Activities, Observers, Permissions, Units } from './src/constants'

// const { AppleHealthKit } = require('react-native').NativeModules

// export const HealthKit = Object.assign({}, AppleHealthKit, {
//   Constants: {
//     Activities,
//     Observers,
//     Permissions,
//     Units,
//   },
// })

// Temporary workaround per:
// https://github.com/facebook/react-native/issues/29228#issuecomment-2345062090
const NativeModules = require('react-native').NativeModules
export const HealthKit = {
  isAvailable: NativeModules.AppleHealthKit.isAvailable,
  initHealthKit: NativeModules.AppleHealthKit.initHealthKit,
  getDailyStepCountSamples: NativeModules.AppleHealthKit.getDailyStepCountSamples,
  getSamples: NativeModules.AppleHealthKit.getSamples,

  Constants: {
    Activities,
    Observers,
    Permissions,
    Units,
  },
}

module.exports = HealthKit

An example of the error message a user would encounter is:

_reactNativeHealth.default.isAvailable is not a function (it is undefined)
