            Bug ID: 189222
           Summary: [Cocoa] Crash using KVO for 'serverTrust' property of
                    WKWebView - "this class is not key value
                    coding-compliant for the key serverTrust"
           Product: WebKit
           Version: Safari Technology Preview
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Keywords: InRadar
          Severity: Normal
          Priority: P2
         Component: WebKit API
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: mitz at webkit.org

<rdar://problem/33283179>

WKWebView.h says that the class is key-value observing (KVO) compliant for the serverTrust property, and the implementation correctly reports changes to the property’s value, but it fails to make the property key value coding-complaint, so trying to get it using -valueForKey: either directly or as a side-effect of using specifying NSKeyValueObservingOptionNew or NSKeyValueObservingOptionOld results in an exception.

Patch forthcoming.
