Hello,
I'm having a rare webkit related crash in my app, happens in 0.01% of all sessions last week but represents 30% of all crashes my app is getting.
Unfortunately all I have for investigating the issue is data from hockeyapp crash reporting, I can't reproduce it locally.
My app uses webviews to display content but also includes Google Admob and mediation partners which AFAIK use webviews for running some JS.
Would appreciate any advice on what I could do to track down this crash.
The crash has the following stacktrace.
It only happens on iOS 11 from what I can tell.
objc_msgSend() selector name: _isValid
