Question

我试图在我的Flutter应用程序中添加Firebase支持，但遇到一个问题，我在互联网上搜索了很多次+堆栈溢出，但根本没有任何解决方案。

有人说这是Swift的问题，但我不确定。

以下是我在尝试构建应用时从Android Studio获取的日志。

Launching lib/main.dart on iPhone XR in debug mode...

Please address deprecated @objc inference warnings, test your code with “Use of deprecated Swift 3 @objc inference” logging enabled, and then disable inference by changing the "Swift 3 @objc Inference" build setting to "Default" for the "Runner" target.

            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Could not build the application for the simulator.

这是在我添加Firebase FlutterFire插件（我需要时全部使用）阅读本指南之后发生的：

你们有什么解决方案吗？谢谢。

我的某些文件可能会有所帮助

Podfile

# Uncomment the next line to define a global platform for your project
# platform :ios, '9.0'

target 'Runner' do
  # Comment the next line if you're not using Swift and don't want to use dynamic frameworks
  use_frameworks!

  # Pods for Runner

  pod 'Firebase'
  pod 'Firebase/Core'

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# Read more about versioning at semver.org.

# For information on the generic Dart part of this file, see the

# The following section is specific to Flutter.
flutter:

  # The following line ensures that the Material Icons font is
  # included with your application, so that you can use the icons in
  # the material Icons class.

  # To add assets to your application, add an assets section, like this:
  # assets:
  #  - images/a_dot_burr.jpeg
  #  - images/a_dot_ham.jpeg

  # An image asset can refer to one or more resolution-specific "variants", see
  # https://flutter.io/assets-and-images/#resolution-aware.

  # For details regarding adding assets from package dependencies, see
  # https://flutter.io/assets-and-images/#from-packages

  # To add custom fonts to your application, add a fonts section here,
  # in this "flutter" section. Each entry in this list should have a
  # "family" key with the font family name, and a "fonts" key with a
  # list giving the asset and other descriptors for the font. For
  # example:
  # fonts:
  #   - family: Schyler
  #     fonts:
  #       - asset: fonts/Schyler-Regular.ttf
  #       - asset: fonts/Schyler-Italic.ttf
  #         style: italic
  #   - family: Trajan Pro
  #     fonts:
  #       - asset: fonts/TrajanPro.ttf
  #       - asset: fonts/TrajanPro_Bold.ttf
  #         weight: 700

AppDelegate.swift

import UIKit
import Flutter
import Firebase


@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
    override func application(
        _ application: UIApplication,
        didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?
        ) -> Bool {
        GeneratedPluginRegistrant.register(with: self)
        return super.application(application, didFinishLaunchingWithOptions: launchOptions)
    }
}

Answer 1

这种情况是由于Pod的安装中断引起的。因此，首先您需要重新安装二进制文件，然后运行以下命令清除项目目录中的项目缓存：

rm -rf "${HOME}/Library/Caches/CocoaPods"
rm -rf "`pwd`/Pods/"

然后再次安装，直到结束：

pod install

Answer 2

对我来说，我删除了ios / Flutter / Flutter.framework文件夹，然后再次安装pods pod install，然后就可以了。

H。将Firebase添加到Flutter应用程序时找不到文件
