How to use library only for IOS?

[Luxlorys]

Hey guys, i created Turbo module using npx create-react-native-library with Kotlin & Obj-c but the thing is that i want to use this module only for IOS since i created library to manage some IOS native things.

Sorry if i'm not that descriptive.

just delete the android folder and any code and scripts referencing android

i've tried to delete android folder, also removed references to android here
package.json

"codegenConfig": {
    "name": "RNAppleHealthKitSpec",
    "type": "modules",
    "jsSrcsDir": "src",
    "outputDir": {
      "ios": "ios/generated",
      "android": "android/generated"
    },
    "android": {
      "javaPackageName": "com.applehealthkit"
    },
    "includesGeneratedCode": true
  },

still could not build example app for android, also android folder was created again after yarn install in root folder.
i'd be really grateful if you check this and add more details what i need to delete (link to repo)

as a temporary solution to this error (same error 4 times for all methods i defined in spec file)

e: file:///Users/andrei/dev/react-native-apple-health-kit/android/src/main/java/com/applehealthkit/AppleHealthKitModule.kt:7:1 Class 'AppleHealthKitModule' is not abstract and does not implement abstract base class member 'requestHealthKitPermissions'.

i just created placeholders with rejects for all methods

package com.applehealthkit

import com.facebook.react.bridge.Promise
import com.facebook.react.bridge.ReactApplicationContext
import com.facebook.react.module.annotations.ReactModule

@ReactModule(name = AppleHealthKitModule.NAME)
class AppleHealthKitModule(reactContext: ReactApplicationContext) :
  NativeAppleHealthKitSpec(reactContext) {

  override fun getName(): String {
    return NAME
  }

  // Placeholder for requestHealthKitPermissions
  override fun requestHealthKitPermissions(promise: Promise) {
    promise.reject("Unsupported", "HealthKit is not supported on Android.")
  }

  // Placeholder for getSteps
  override fun getSteps(daysBefore: Double, promise: Promise) {
    promise.reject("Unsupported", "HealthKit is not supported on Android.")
  }

  // Placeholder for getHeartRate
  override fun getHeartRate(daysBefore: Double, promise: Promise) {
    promise.reject("Unsupported", "HealthKit is not supported on Android.")
  }

  // Placeholder for getMeasurement
  override fun getMeasurement(promise: Promise) {
    promise.reject("Unsupported", "HealthKit is not supported on Android.")
  }

  // Placeholder for getAppleMoveTime
  override fun getAppleMoveTime(daysBefore: Double, promise: Promise) {
    promise.reject("Unsupported", "HealthKit is not supported on Android.")
  }

  companion object {
    const val NAME = "AppleHealthKit"
  }
}

I hope there is a better solution
