Xamarin Forms AppCenter 崩溃，发送到类的选择器无法识别

转载作者：行者123 更新时间：2023-12-03 23:26:34

我最近更改了我的项目以使用 .NET core 2，并且我目前正在重新测试 WPF、Android 和 iOS。
不幸的是，我也一直在升级我的 Nugets 以使 UWP 项目正常工作，今天早上 Xcode 也更新到了版本 12.0 (12A7209)，然后是 Visual Studio for Mac，所以我不太确定应该责备什么。
我确实遇到了 App Center 不想从 3.4.1 升级到 3.4.2 的问题，所以我求助于清除我的 Nuget 缓存并手动编辑项目解决方案，现在它们都指向 3.4.2(截至 23 日最新2020 年 9 月)。
以下错误似乎是根本原因，但我不明白我需要做什么来解决它？

NSInvalidArgumentException Reason: +[MSAnalytics sharedInstance]: unrecognized selector sent to class 0x1eb4f2678

最佳答案

这是因为与某些 Apple 私有(private)框架的类名冲突。苹果添加了MSAnalytics iOS 14 中的类，因此它与 App Center SDK 冲突。
3.4.3已发布此问题的修补程序。在这个补丁中，MSAnalytics更名为 MSACAnalytics以避免这种冲突。
