AppleError and other enums are not available on runtime

[petetnt]

Hi,

I am trying to use the AppleError enum in a runtime check, which looks something like this:

import {
  appleAuth,
  AppleError
} from '@invertase/react-native-apple-authentication';

...

export function isNativeFirebaseError(
  error: any
): error is ReactNativeFirebase.NativeFirebaseError {
  return error && error.code && error.message;
}


try {
  // do stuff
} catch (err) {
  if (isNativeFirebaseError(err) && err.code === AppleError.FAILED) {
    // do stuff
  }
}

The issue is that while the typechecking passes, AppleError enum is not available at runtime as it's declared in

react-native-apple-authentication/lib/index.d.ts

Line 131 in cadd7ca

export declare enum AppleError {

console.log(AppleError) // undefined

However, the code is correctly assigned in the error:

try {
  // do stuff
} catch (err) {
  if (isNativeFirebaseError(err) && err.code === "1004") {
    // does not throw, it's ok!
  }
}

This also affects all the other declared enums on that file too. I think the easiest fix would be removing the declare keyword from the typedef or marking them as const instead.
