        iOS application is implemented in WebView format. Behavior of YouTube embedded player implemented with html in WebView is invalid. Specifically, there are the following events. While loading an embedded HTML page using an iframe tag, the application terminates abruptly. This event occurred in iOS 10.2, and it does not occur in other versions. Are there past cases and countermeasures?

         

        The following is the contents of the application crash log.
