问题描述
每当我尝试在Xcode中运行Unity构建的项目时，都会收到大量与Firebase的Firestore相关的错误。仅在Windows上使用Unity for Android运行时，我没有任何错误。
我正在使用Firebase 6.15.2，并且正在尝试使用Xcode v11.6编译我的iOS应用。 Xcode iOS项目是由Windows上运行的Unity 2019.4.4f1创建的。

在Unity包管理器中，我可以确认“ Cloud Firestore for Firebase”的版本为6.15.2。但是，当生成的Podfile的版本为1.15.0时，看起来有点奇怪。这是问题吗？
source 'https://github.com/CocoaPods/Specs.git'
platform :ios,'10.0'
target 'UnityFramework' do
pod 'Firebase/Analytics','6.24.0'
pod 'Firebase/Core','6.24.0'
pod 'Firebase/RemoteConfig','6.24.0'
pod 'FirebaseCrashlytics','4.1.0'
pod 'FirebaseFirestore','1.15.0'
end
解决方法
在撰写本文时，我还不了解所有问题，但我想发布一个答案，@ Ajordat帮助我找到了答案。如果遇到其他问题，我会进行更新。
我缺少一个.xcworkspace文件，这是我应该在XCode中打开的文件，以免出现上述错误。要获取此丢失的文件，我需要在Mac的项目文件夹中的终端窗口中运行pod install。
我还没有找到在Windows上执行此部分操作的方法，但这不是必需的，因为无论如何您都需要XCode来执行仅在Mac上运行的最终编译。话虽如此，我发现这是为了防止任何人感兴趣：Using CocoaPods on Windows
,我认为1.15.0版本可能特别适合Firestore。出于好奇，Unity是否可以与Firebase 5.3.0之前的Firebase版本一起使用？
