First, please bear with me, I'm more of a Native dev on iOS side.
I've successfully made this "slim binding" by following this youtube video. The binding spits out UIView and Android View, which I can use on each Xamarin.iOS and Xamarin.Android app. As titled, the part that I can't figure out is how to use these bindings on XAML?
The closest thing I found is this: https://www.xamboy.com/2020/07/28/creating-a-binding-library-in-xamarin-part-2/ but that example pushes a whole view controller rather than just a simple view where I can have other things on top.
For context, the slim binding I made is for AWS IVS Player. Can't figure out any other way to have a player that has 2-3 secs of latency other than using their own player.

So I'm trying to migrate from using UIWebView to WKWebView for Xamarin Forms iOS but I have a few questions because this all seems to be pretty new and none of the resources are helping me online.
https://github.com/xamarin/Xamarin.Forms/pull/7367
I came across this link though, and apparently the WKWebview is not the default for Xamarin.Forms for 4.0+ and so,
1) I'm currently using Xamarin Forms 3.4.0.x. From my understanding, is all I have to do to get the WKWebView upgrading to 4.4.0.991477, the latest build?
2) Follow up to question 1, how would I not change any code because my cs files contain "using UIKit", which is the namespace for UIWebView, is it not?
3) In this link, it seems like there is no design change at all.. but I thought that WKWebView contained a URL link at the top of the page, which UIWebView does not, which is correct?
Thanks!
1) If you have only cross-platform code, then yes there is nothing that you need to worry about, it just works.
2) As you suggest that you have UIKit in your code, then obviously that won't work. UIKit is not Xamarin.Forms API and basically you don't use Xamarin.Forms in this case, but rather Xamarin.iOS.
3) Neither of those controls display URL.
I have a webview that contains a video in my Xamarin forms application. Android does not allow for full screen but iOS does I know I could implement the WebChromeClient but I have only seen this done for Xamarin Android and not for forms. I can't seem to get it to work. Any ideas?
If you need to access the underlying native controls and their properties, methods and events, you do that with custom renderers.
I'm glad I found this because I don't think I could of done it on my own.

We've begun evaluating Xamarin for a up and coming project involving both iOS and Android, with the overriding intention to produce a single UI layer (and some share code, obviously) (I'm also new to C#)
TL;DR
I've begun exploring Xamarin on iOS. I started with the Phoneword example and it worked well enough.
The first issue I found was running the code on the iPhone X, which I was able to solve by using MainPage.On<Xamarin.Forms.PlatformConfiguration.iOS>().SetUseSafeArea(true); in the platform App class
While testing this, I noticed some issues with the ListView not scrolling properly (the core issue was actually with the platform padding).
I then used (MainPage as Xamarin.Forms.NavigationPage).On<iOS>().EnableTranslucentNavigationBar(); to enable translucent navigation bars (as we're targeting iOS 11+) and now everything appears under the navigation bar.
This is easily fixed in xCode and after some research I've found that I need to be using UIKit.UIViewController.EdgesForExtendedLayout Property, the immediate problem I'm facing is, the only "snippets" of code I can find are from the View is displayed under status bar in iOS 7 and EdgesForExtendedLayout doesn't help forum post.
Issue at hand...
The example solution snippets posted seem to be making use of a platform (iOS) specific solution. The problem is, I want to keep using the "cross-platform" code in the "platform" project and simply provide some custom configuration for the iOS platform which can apply these states.
I understand it could be possible to use a renderer, but this seems to counter-interactive, as I'd need one for both iOS and Android, where the platform page is doing just fine as it.
I understand that I could setup a DependencyService, but this seems annoying to have to include a specific "configuration" service just to solve this issue for iOS
I was hoping it might be possible to setup a iOS Page which would "override" some of the functionality of the platform page and would allow me to make use of things like viewDidLoad so I can apply the iOS specific configurations on a page by pages bases, so we could keep the platform page as it, but when running under iOS, it would provide me access to iOS life cycle of the actual view...
I've been trying to search the documentation and tutorials and haven't yet come across anything which would seem to do this or something similar (not to say there isn't one, but I'm just not finding it).
I'm building an app in NativeScript {N} where I'm implementing a webview.
All of this is working fine, but in my webpage, I would like to get some JS debug statements. How can I see the webview console.log output?
Previously I was able to "inspect" it through Safari, but that option is not presented in the "Develop" menu anymore.
If like me you could not figure out how to do this using the webview proivded by nativescript you'll need to install this plugin to get what you need.

I provides a lot more features more than the stock. Basically, it allows you to emit events to the android from the webview layer. The author provides a good tutorial on this.
Say I build a super mobile friendly web application that I want in the Play Store for Android users to be able to download.
Could I use Xamarin to:
Wrap the entire mobile app as a single WebView
Register for mobile push notifications
Essentially shortlining an MVP of an android app by using an existing web app? If so, is there any well-known process or documentation that demonstrates this?
Probably the best approach for you would be using Xamarin Forms with one or more pages containing only web views.
I don't love Xamarin Forms because usually for me Xamarin Android+iOS gives a better result in similar time, but your app would be so simple that doesn't make sense to do it with Xamarin Android.
Make sure that your web app will show only what makes sense to be shown in your app, otherwise you risk to see double header/footer, useless buttons... but if the website is yours adding a few parameters to change a bit the UI won't be a problem I guess.
Have a look at this example:
https://github.com/xamarin/xamarin-forms-samples/tree/master/WorkingWithWebview
Another approach is the use of Razor to build your pages in html directly inside your app, but if I understood well it's not what you need:
https://developer.xamarin.com/guides/cross-platform/advanced/razor_html_templates/
Although it is technically possible to do this as the previous answer has suggested. I would recommended firstly reviewing, the relevant stores guidelines on submissions. Apple for example will not allow a submission to their store of any application that simply mirrors the functionality of a website. I suspect Google's would likely be the same.
However that said, to answer your question, Xamarin.Forms would be appropriate for a simple application like the one you are suggesting. Or if you prefer to build to a specific OS, then in iOS with Xamarin you would use the Safari View Controller that was added in it's xcode 8.1 release. Android uses something similar as does windows.
EDIT:
You can use the Web View control in Xamarins Andorid native PCL project to encapsulate your mobile friendly website within an application here is the documentation:
Xamarin Android Developer link to Android Web View
As for push notifications, yes this is perfectly possible using Xamarin.Android. and varies on implementation depending on what you want to use as the back end to handle them, I.E. Azure's notification hub etc.
