使用Cocoapods添加Firebase时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

和a

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：

我使用的是Swift 3.0

有什么建议么？ 干杯

Answer 1

就像我发布这个问题一样，我找到了解决方案......

您必须在pod安装后使用.xcworkspace文件而不是.xcodeproj文件。

为了这样做，在finder中打开项目的位置，然后用Xcode打开.xcworkspace文件（这个文件是由Cocoa Pods创建的）。

Answer 2

我刚刚遇到了与我的新项目相同的问题，在尝试了很多事情之后，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清理你的项目，也（如果还不够）清除Library - > Developer - > Xcode-> DerivedData文件夹并尝试重建你的项目。

在终端中尝试这个：

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