[Bug] Forms9Patch webview.toPDF crashes without exception on iOS-Device

[technik5]

Description

Hello sir Baskren,
the line in your example:
if (await webView.ToPdfAsync("output.pdf") is ToFileResult pdfResult)
crashes instantly even if the html-source of the webview contains only
"

"

the bug seems only to exist on iOS and not on Android, where everything works as expected.
The webview displays everything normaly.
Even in a try - catch - block it won't be catched...could it be a problem with rights?

Steps to Reproduce

1. Load all nuget-files for pcl,android and ios
2. create a xaml-page with Forms9Patch similar to the example
3. copy code of examplefile
4. create app on physical iOS-Device
5. click-sharebutton -> crash

Expected Behavior

getting a pdf to share

Actual Behavior

crash without exception to homescreen of ios-device

I have a similar problem but with try catch block i got this exception: "WebView has zero width or Height".
On Android my code runs perfectly.

I'm using iOS 15.0 with a Physical device.

System : Xcode 13.1, Visual studio 8.10.13

@xamdinesh : My apologies, I am no longer supporting Forms9Patch. If you're interested in seeing how to fix this in the source code, you can check out the most recent version of this functionality as implemented for the UNO Platform here: https://github.com/baskren/P42.Uno.HtmlExtensions.
