我在这里找到了一个类似于我的解决方案 iOS Swift Linker Command Failed with exit code1

所以现在我的问题是如何从项目中仅删除 firebaseanalytics 依赖项？或者任何其他消除错误的解决方案也可以工作。

【问题讨论】：

标签： ios xcode firebase

【解决方案1】：

经过一番苦苦搜索，我找到了答案，我已经安装了两个 pod 1. Firebase/核心 2. 谷歌/云消息

我从 nano podfile 中删除了这两个文件，并使用 Firebase/Messaging 对其进行了更新，然后进行了 pod 更新，错误消失了。

【讨论】：

我遇到了同样的问题。在此之后您是否能够使用 GCM，或者您必须在应用程序中重写通知处理？
