[iOS] Firebase Messaging: TypeError: Cannot set property 'delegate' of null

[LookinGit]

When on iOS call firebase().messaging(), get this error. I found an error in constructor of class Messaging for iOS

firebase/packages/firebase-messaging/index.ios.ts

Line 48 in 8549685

this.#native.delegate = this.#delegate;

in constructor on 48 line.

This error prevents the constructor from finishing executing the code after this line. For this reason, the first call to the function await firebase().messaging().requestPermission() will not work, as and any other methods.

How reproduction this error (only on iOS):

import { firebase } from '@nativescript/firebase-core'
import '@nativescript/firebase-messaging'

...
const messaging = firebase().messaging()
const status = await messaging.requestPermission({ ios: { alert: true } }) // this line not will working
...

I may be wrong, but i think what this issue #24 also related to this error

---

Until this bug is fixed, may use a temporary solution (hook):

if (isIOS) {
  ;(async () => firebase().messaging())()
}
const status = await firebase().messaging().requestPermission({ ios: { alert: true } })

add this before firebase().messaging().anyMethod()

Call a firebase().initializeApp() when init app
