[IOS] The default FirebaseApp instance must be configured before the default Authinstance can be initialized

Hi @NathanWalker

When I call firebase().auth().addAuthStateChangeListener that will throw error

 NativeScript encountered a fatal error: Uncaught Error: The default FirebaseApp instance must be configured before the default Authinstance can be initialized. One way to ensure this is to call `FirebaseApp.configure()` in the App Delegate's `
  application(_:didFinishLaunchingWithOptions:)` (or the `@main` struct's initializer in SwiftUI).
  at
  get native(file: app/webpack:/--/node_modules/@nativescript/firebase-auth/index.ios.js:1237:0)
  at addAuthStateChangeListener(file: app/webpack:/--/node_modules/@nativescript/firebase-auth/index.ios.js:907:0)

to prevent this error I should declare init on a delegate applicationDidFinishLaunchingWithOptions then it work !

Do you have an idea what happen

Thanks

从 app/webpack:/--/node_modules/@nativescript/firebase-auth/index.ios.js 中失败的 addAuthStateChangeListener 路径开始，尤其关注第 907 行和第 1237 行附近的引用。复现 iOS 的初始化顺序，并将其与报告中的 applicationDidFinishLaunchingWithOptions workaround 进行比较；当默认 Firebase 应用未由调用方显式配置时，身份验证不再抛出异常，即表示完成。
