分析Xamarin.iOS崩潰報告

Question

我們的Xamarin Forms應用程序在我們的一個iOS測試設備上間歇性崩潰，而且我很難在崩潰報告中找到任何有用的東西。

我發現的所有教程和示例似乎都從應用程序本身引用了行號和方法/屬性，但我在這裏看到的所有內容都是單聲道庫調用。

我也無法在本地重現此問題。任何人都可以提供任何指導或建議一個很好的資源，我可以用它來確定這是什麼崩潰報告實際上是報告：

我所看到的，就是當你嘗試在運行一些代碼的東西是怎麼了？ ui線程。以下行告訴我UIKit_UIKitSynchronizationContext__Postc__AnonStorey0__m__0 (UIKitSynchronizationContext.cs:24)。

很難確切地說出問題所在或者問題所在的文件。也許實現見解是另一個崩潰記錄器。所以你可以獲得更多關於崩潰的信息。
