Nativescript: webView.request.URL is undefined for trace and make iOS crash

[AntonioCuevaUrraco]

trace.write("UIWebViewDelegateClass.webViewDidStartLoad(" + webView.request.URL + ")", trace.categories.Debug);

Which platform(s) does your issue occur on?

IOS

Please provide the following version numbers that your issue occurs with:

This is related only to tns-core-modules: The version affected is 2.2.1 but it doesn't seams to be fixed on the latest tns-core

Please tell us how to recreate the issue in as much detail as possible.

I have no idea how to reproduce the issue because is coming form our app on the store. I can not know what the end user is clicking. Just make sure that webView.request is something before trying to access URL

"2": "TypeError: null is not an object (evaluating 'webView.request.URL') ",
"3": "",

@AntonioCuevaUrraco @davecoffin Could you share steps to reproduce the crash so that we can add unit-test?

[davecoffin]

Its sort of hard to reproduce, it happens with certain URLs and I'm not sure why. But my fix just in #4830 just brings it in line with how its handled in webViewDidFailLoadWithError further down in the file, it appeared to just be an oversight.

[hshristov]

Can you share the URL that you manage to reproduce it?

[davecoffin]

Well thats just the thing, that function is being invoked with no URL, thats why its crashing:
