Question

在我的Xamarin Forms项目中，当我调用一个使用来自iOS项目的Realm（具有公共代码的项目）的函数时，我得到以下异常。从Android项目它工作正常。尝试使用Realm.GetInstance()获取Realm实例时发生异常。知道为什么会这样，以及如何解决它？

{System.TypeInitializationException: The type initializer for 'Realms.SharedRealmHandle' threw an exception. ---> System.ExecutionEngineException: Attempting to JIT compile method '(wrapper native-to-managed) Realms.SynchronizationContextEventLoopSignal:GetCurrentSynchronizationContext ()' while running in aot-only mode. See https://developer.xamarin.com/guides/ios/advanced_topics/limitations/ for more information.
