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：
Apple Mach-O链接器错误组

我使用的是Swift 3.0
有什么建议？干杯
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）。
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：
