Xamarin iOS Firebase native 链接失败

Question

更新 Firebase 库后，出现以下错误:

MTOUCH : error MT5210: Native linking failed, undefined symbol: _APMAnalyticsConfiguration. Please verify that all the necessary frameworks have been referenced and native libraries are properly linked in.Blockquote

MTOUCH : error MT5210: Native linking failed, undefined symbol: _APMAppMeasurementOriginFirebase. Please verify that all the necessary frameworks have been referenced and native libraries are properly linked in.

MTOUCH : error MT5210: Native linking failed, undefined symbol: _APMIsAnalyticsCollectionEnabled. Please verify that all the necessary frameworks have been referenced and native libraries are properly linked in.

MTOUCH : error MT5210: Native linking failed, undefined symbol: _APMSafelistedEventsOptionKey. Please verify that all the necessary frameworks have been referenced and native libraries are properly linked in.

我尝试了以下方法:

删除 obj 和 bin 文件夹

清理项目

初始化 Firebase 核心 (Firebase.Core.App.Configure();)

我已经尝试了所有链接器行为选项。
我引用了以下 Firebase 库:

Xamarin.Firebase.iOS.Analytics (6.4.1)

Xamarin.Firebase.iOS.CloudMessaging (4.3.0)

Xamarin.Firebase.iOS.Core (6.6.6)

Xamarin.Firebase.iOS.DynamicLinks (4.0.8)

Xamarin.Firebase.iOS.Installations (1.1.1)

Xamarin.Firebase.iOS.InstanceId (4.3.3)

有谁知道如何解决这个问题？

不幸的是，在这种情况下您无能为力。该错误与不正确的链接有关。来自 Xamarin 的家伙在一次升级后搞砸了绑定(bind)。您可以阅读有关在 Xamarin here 中使用 native 库的更多信息更具体地说here .

但是，您仍然可以做一些事情来帮助 - 找出导致问题的包以及从哪个版本开始发生问题。然后，在 Google API 的官方 GitHub 存储库中报告它here .

附言我已经通过issues并且还没有看到这个确切的错误列表。已经存在(并且仍然存在)许多绑定(bind)问题，等待修复。因此，为了加快速度，请与问题的开发人员讨论它，希望他们能够快速解决它。
