使用 Cocoapods 添加 Firebase 时的 Apple Mach-O 链接器错误组

Question

我最近尝试将 Firebase 添加到我的应用程序中。使用 Cocoapods 我做了一个

pod init

还有一个

pod install

这是我的 Podfile：

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

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

  # Pods for A
pod ‘Firebase’
end

在尝试构建我的应用程序时，我收到以下错误：

我正在使用 Swift 3.0

有什么建议吗？干杯

Answer 1

我在发布这个问题时找到了解决方案...

您必须在 pod install 后使用 .xcworkspace 文件，而不是 .xcodeproj 文件。

为此，请在 finder 中打开项目的位置，然后使用 Xcode 打开 .xcworkspace 文件（该文件由 Cocoa Pods 创建）。

Answer 2

我刚刚在我的新项目中遇到了同样的问题，在尝试了很多东西之后，我终于通过更新我的 pod 解决了我的问题：

pod update
Installing Firebase 4.7.0 (was 4.1.1)
Installing FirebaseAnalytics 4.0.5 (was 4.0.3)
Installing FirebaseCore 4.0.12 (was 4.0.6)
Installing FirebaseInstanceID 2.0.7 (was 2.0.2)
Installing GoogleToolboxForMac 2.1.3 (was 2.1.1)

从 Xcode 中清除您的项目，同时（如果还不够）清除 Library -> Developer -> Xcode-> DerivedData 文件夹并尝试重新构建您的项目。

在终端试试这个：

• git 状态
• git 分支
• git add -A
• git commit -m ''你的评论...''
• git push origin（你的分支名称）
