ios - 每当我添加 FlutterFire 包时，Firebase 就会停止工作

Question

每当我尝试为 iOS 设置 firebase 时，一切都会正常工作，直到我将“cloud_firestore:”包(或任何其他 FlutterFire 包)添加到 pubspec.yaml 文件夹中。我每次都会收到类似的错误消息。唯一不会引发错误的与 firebase 相关的包是 firebase_core 包。我最常见的错误输出粘贴在下面:

*Xcode's output:
↳
    /Users/Jon/crud/ios/Pods/GoogleUtilities/GoogleUtilities/Network/GULNetw
    orkURLSession.m:55:3: warning: 'NSURLSession' is only available on iOS

    #import "FCachePolicy.h"
            ^~~~~~~~~~~~~~~~

我尝试使用 github 引用创建一个新的 FCachePolicy.h 文件夹并将其复制进去，但这只会导致向我报告未找到更多 Pods 文件的无尽列表。此时我既感到非常沮丧，又失去了想法 - 此时任何帮助或建议将不胜感激。

如果您添加 firestore 包，您还需要向项目添加 GoogleService-Info.plist

为此，您需要创建一个 Firebase 项目、添加您的 iOS bundle ID 并下载其他 plist 文件。

有关如何获取该文件以及如何将其添加到项目中的完整教程，您可以在此处的官方 Firebase Flutter Codelab 中获取(第 7 步):
