问题

您好，我在 iPhone 模拟器上运行 Flutter 应用时遇到了困难。它停留在“Xcode build done”上。顺便说一句，它在 Android 模拟器上运行得很好。

这是我第一次在这里提问，所以如果需要更多信息，或者有什么不合适的地方，请告诉我。任何形式的帮助（或评论）将不胜感激。谢谢。

尝试手动启动应用的视频： https://user-images.githubusercontent.com/60031762/141050073-648a9893-0e33-425e-9c9d-24966bf1be39.mov

附言我还在flutter github上开了一个issue：https://github.com/flutter/flutter/issues/93361

以下是详细信息：重现和记录的步骤。

复制步骤

操作系统：macOS Big Sur 11.6，连接到我的 iPhone 11 pro (iOS 15.1) 的 USB 网络（热点）。

克隆 https://github.com/kws1207/friendship/tree/main/where_to_eat 并打开项目。
运行模拟器，打开 iPhone 12 Pro Max、iOS 14.4。
执行flutter run。
选择2中打开的模拟器。

预期结果：

Launching lib/main.dart on iPhone 12 Pro Max in debug mode...
Running Xcode build...                                                  
 └─Compiling, linking and signing...                         8.3s
Xcode build done.                                           268.6s
Installing and launching...
Flutter run key commands.
r Hot reload. ????????????
R Hot restart.
h List all available interactive commands.
d Detach (terminate "flutter run" but leave application running).
c Clear the screen
q Quit (terminate the application on the device).

Running with unsound null safety
For more information see
https://dart.dev/null-safety/unsound-null-safety

实际结果：

Launching lib/main.dart on iPhone 12 Pro Max in debug mode...
Running Xcode build...                                                  
 └─Compiling, linking and signing...                         8.3s
Xcode build done.                                           268.6s
(it stucks here)

【解决方案1】：

请检查 list_screen 中的错误，第 548 行和第 690 行。删除 Podfile.lock。跑干净。然后运行flutter run。使用项目根目录中的cd ios 导航到终端中的 ios 文件夹。运行pod install。现在，一旦安装了 pod，在 xcode 中打开 xcworkspace 文件，您可能会看到一条警告，要求您升级最低版本的 ios。允许它升级设置。现在从 xcode 中选择模拟器并点击播放。一旦它在 xcode 上运行良好，您应该也可以直接从 Android Studio 运行它。

您好，感谢您的评论。目前我正在努力解决一个错误：由于未捕获的异常“NSInvalidArgumentException”而终止应用程序，原因：“在捆绑包 NSBundle 中找不到名为“Main”的情节提要。你能帮帮我吗？

由于该链接是关于实际 iOS 设备的，因此似乎并非如此。

【解决方案2】：

您需要将 firebase 配置初始化到 appdelegate.swift 文件中。

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)
    
    if FirebaseApp.app() == nil {
        FirebaseApp.configure()
    }
    
   // FirebaseApp.configure()
    
   return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
}

【讨论】：

它产生两个错误。 /Users/kws/Onedrive/projects/friendship/where_to_eat/ios/Runner/AppDelegate.s wift:12:8: 错误：如果 FirebaseApp.app() == nil { /Users/kws/ 在范围内找不到“FirebaseApp” Onedrive/projects/friendship/where_to_eat/ios/Runner/AppDelegate.s wift:13:9: error: cannot find 'FirebaseApp' in scope FirebaseApp.configure() // 需要添加这个
你不是在顶部添加了这一行吗？ “导入 Firebase”
我已经添加了完整的代码。
"import Firebase" 丢失。然而，问题并没有解决。我正在努力解决错误 [由于未捕获的异常“NSInvalidArgumentException”而终止应用程序，原因：“在捆绑包 NSBundle 中找不到名为“Main”的情节提要]。谢谢。
添加后请使用flutter clean、flutter pub get和flutter run命令检查或关闭xcode重新打开。

【解决方案3】：

请在 Xcode 的 buildSettings 中为 iOS 应用尝试这个添加新用户定义

键EXTRA_FRONT_END_OPTIONS，值为--no-sound-null-safety

并清除派生数据并再次重建它，然后运行它。

【解决方案4】：

问题是我删除了“复制捆绑资源”中的所有组件。我在上面添加了 Main.storyboard，应用运行良好。
