【问题描述】：
我正在尝试按照步骤将 Firebase 连接到 Flutter 生成的 iOS 应用。
在最后一步中，将 FirebaseApp.configure() 行添加到 AppDelegate.swift 文件中时，应用程序构建正常，但随后在执行时崩溃，表明 Signal Abortion on线程 1... 线程 1：信号 SIGABRT
AppDelegate.swift 中的代码如下：
import UIKit
import Flutter
import Firebase
@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
override func application(
_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
) -> Bool {
GeneratedPluginRegistrant.register(with: self)
FirebaseApp.configure()
return super.application(application, didFinishLaunchingWithOptions: launchOptions)
};
}
Xcode 提供的完整错误日志如下：

上面的错误日志中很有趣的一行：
由于未捕获的异常“com.firebase.core”而终止应用，原因：“[FIRApp configure];（Swift 中为FirebaseApp.configure()）在您的项目中找不到有效的 GoogleService-Info.plist .请从https://console.firebase.google.com/下载一个。'
所以... 该消息清楚地表明 GoogleService-Info.plist 可能存在一些问题，就像它不存在一样......除了它确实存在，从 Firebase 新下载，它位于在正确的文件夹中，我已经彻底检查了 plist 的内容，以验证 Bundle ID、Team ID 和所有其他信息是否正确...
有人可以提出一些建议来解决这个问题吗？
谢谢
【问题讨论】：
-
您是否确保 GoogleService-Info.plist 包含在您的目标中？
-
是的！感谢您的评论...确实，阅读该错误消息，这是人们会想到的第一件事...但是，GoogleService-Info.plist 确实存在，是从 Firebase 新下载的，它位于正确的文件夹中，并且我已经彻底检查了 plist 的内容，以验证 Bundle ID、Team ID 和所有其他信息是否正确......这就是我认为这个问题有点奇怪的原因，也是我想问的原因这里的社区......
-
此错误通常发生在文件不包含在目标中时。只是将文件放在项目中的正确位置并不意味着它包含在您的目标中。
-
非常感谢你，安德鲁。你的评论确实很有价值。如果您愿意帮助我更好地理解，如何确保该文件包含在目标中？我对 Xcode 完全陌生，在我熟悉的 AndroidStudio 中似乎不会发生这样的事情......
