this resolved bug and you do not yet see a matching new report.
When we implement custom WebViewRenderer or accessing it via (WebViewRenderer)RendererFactory.GetRenderer( browser refreshes itself so frequently. If we force to use browser it may cause app crash.
Note: this only happens in tamarin forms iOS project. No problem with windows phone etc.
We'd be happy to help you resolve this issue. Please help us by attaching a reduced reproduction to the bug by starting with a clean Xamarin.Forms project and adding just the code necessary to demonstrate the issue. If you'd do this for us we would very much appreciate it. If you are able to reproduce the issue without modifying the platform specific projects that would eliminate a number of possibilities and likely expedite a resolution. If you need to create a custom renderer instead of submitting that code please explain why the existing forms classes don't work for you.

I've provided a sample project in comment 2. Which is a clean xamarin.forms project (It has just a few lines of code). If you comment line 16 in "WebViewRenderer = (WebViewRenderer)RendererFactory.GetRenderer(basePageInstance.webView);" MainPageRenderer.cs (iOS project) it may work well.
Actually I don't need custom renderer in my current project. I just need to access platform equivalent of xamarin.forms controls. WebView doesn't provide a function to get html of current web page but UIWebView in iOS has some functions for that requirement. Is there any other way to cast xamarin.forms control to platform specific control.
Thank you for taking the time to submit this report. After reviewing the description of this bug, we believe it no longer affects the current version of Xamarin.Forms. If you are still experiencing the issue after updating your packages, please reopen this report with an attached reproduction.
For your convenience, we have created some reproduction best practices viewable here: https://gist.github.com/jassmith/92405c300e54a01dcc6d
