【问题描述】：

我有一个依赖于 Facebook SDK、Firebase 和 Alamofire 的 iOS 应用。我已经附加了 pod 文件，根据 GitHub 问题上的一个线程，我已经添加了 GoogleUtilities，但它仍然会引发相同的错误。

Undefined symbols for architecture x86_64:

ld: symbol(s) not found for architecture x86_64

这是相同的 pod 文件

target 'TestApp' do
  # Comment the next line if you don't want to use dynamic frameworks
  use_frameworks!

  # Pods for TestApp

pod 'Alamofire', '~> 5.0'
pod 'Bond'
pod 'Purchases', :git => 'https://github.com/daneal/RevenueCat.git'
 

pod 'FacebookCore'
pod 'FacebookLogin'
pod 'FacebookShare'
pod 'Firebase/Auth'
pod 'Firebase/Core'
pod 'PromisedFuture'
pod 'GoogleUtilities', '~> 6.6.0'

end

任何指针都将有助于理解问题并解决它，谢谢

【问题讨论】：

上述所有方法都存在并且是“外部”但不知何故他们没有得到链接。
见github.com/firebase/firebase-ios-sdk/issues/5801
@PaulBeusterien 感谢您的回复，但在我的情况下，问题也与模拟器有关，尚未尝试为设备构建。

【解决方案1】：

将以下行添加到您的 pod 文件中

$RNFirebaseAsStaticFramework = true

【解决方案2】：

我正在将一个项目从 Carthage 移植到可可豆荚中，并且 Carthage（Carthage 目录）中存在一些剩余的构建文件，这导致了构建问题，我认为这本身就可以解释。删除并重建后，一切正常。可能会帮助某人。
