We have just tried with WkWebView and we get the same error:

__abort_with_payloadmeans that some library code has gone out of its way to crash your app. If you run your app outside of Xcode, does it still crash? If so, does that generate a crash log? If so, take a look at the crash log to see if it contains any clues.
