我不断地在周围寻找，却找不到任何解决方法。我用Unity构建了我的IOS项目，编译得很好。我只是得到运行时的错误，我似乎根本无法解决。
当我用Unity测试模式运行时，它运行得很好，（没有错误和配置加载）。
当我在IOS设备上编译运行时，就会出现一堆运行时错误，我甚至无法通过加载界面，因为Firebase无法加载。
最上面的只是所有的dupe错误（有两个以上，但我只包括例子），最下面的是 "无法配置Firebase应用 "的错误。
另外：我在Windows上使用IOS Project Builder构建项目，所以我手动添加了&；链接了框架。我无法添加FirebaseApp.configure bc我不是在swift上。

如果你不能使用Unity，这就有点棘手了。Unity的外部依赖管理器(EDM4U)但看起来你的问题可能是缺少GoogleService-Info.plist。一般来说，这将作为EDM4U运行的一部分自动复制过来，但由于你绕过了这一点，你将会想要手动完成它。配置步骤应该在调用 FirebaseApp.DefaultInstance (或初始化任何其他依赖它的单子)。
你可以尝试将文件放在 Assets/StreamingAssets 看看是否能解决这个问题，否则你就得把它移到手动连接框架的地方。请看 这个 如果你需要重新下载它。
如果这还不能解决，请确保你已经遵循了 iOS上手指南 (听起来你已经这样做了)。不要害怕使用CocoaPods。EDM4U就是这样做的.
另外，不要忽略unity bundles下的文件。Assets/Plugins/iOS/Firebase (前。Assets/plugins/iOS/Firebase/libFirebaseCppApp.a). 我知道，很多时候版本控制系统都会排除掉 .a 文件，以避免跟踪构建工件。这些文件大致映射到 C++ SDK，Firebase Unity SDK使用它与底层框架进行通信。C#层主要使用 SWIG 来生成适当的绑定，并做一些额外的工作，使其更方便在Unity中使用。
最后，虽然我不认为从Windows中生成iOS项目有广泛的测试，但我可以看到有一些需求。如果能提交一个bug询问这个问题，会很有帮助的 此处并概述你到目前为止不得不颁布的变通办法。同时提交一份 功能要求 是一个很好的方式来鼓动支持（这适用于任何找到这个答案的人，而不仅仅是OP--噪音越大越好）。
如果有帮助，请告诉我
