ios - 将 firebase 框架添加到 ios 项目时出现链接器错误

Question

我一直在尝试将 firebase 框架添加到我的 ios 应用程序中。我按照这里的说明操作:https://www.firebase.com/docs/ios-quickstart.html .当我尝试编译我的项目，甚至是 firebase 模板项目时，我得到了大量的链接器错误。 (如果有人感兴趣，我可以将它们粘贴在这里，但它有很多文本)firebase 框架需要这些框架，我确保将它们全部包含在内。

libicucore.dylib
CFNetwork.framework
Security.framework
SystemConfiguration.framework

是否还有其他一些我没有列出的框架？我不知道是怎么回事。谢谢您的帮助!

编辑:这是错误

对不起。我们今天推送了一个新版本，它添加了对 libc++.dylib 的新依赖。如果添加它，它应该会构建。

请注意，当前构建也存在一个问题，无法为 arm64 构建。鉴于此，您可能只想使用以前的版本:https://cdn.firebase.com/ObjC/Firebase.framework-1.0.9.zip

否则，请等待一天左右，我们将整理出最新版本。

带来不便敬请谅解!
