Vision.VNRecognizeTextRequest in Xamarin iOS 13 - xamarin.ios

Does anyone know if Xamarin iOS has support for Vision.VNRecognizeTextRequest. I came across a old post https://github.com/xamarin/xamarin-macios/issues/6830 which says it is not available in Xamarin iOS 13.
What is the latest status?

Based on the issue it seems to be fixed and there are also two Xamarin samples on GitHub using VNRecognizeTextRequest, as you can see here and here.

Cordova wkwebviewonly for ios 6.1

Im using node.js with Cordova for iOS. I upgraded to Cordova 10.0.0 and it doesn't seem to include the wkwebviewonly support. It still seems to reference UIWebView. I wanted to use the wkwebviewonly plugin and everyone seems to have issues when using it with iOS 6 or higher. I have iOS 6.1. Can anyone give insight or help with this? Is there any solution aside fro downgrading to iOS 5? I am new to everything so I may be missing something here. Please help! Thank you :)

Does MtouchSdkVersion setting affect what version of iOS we can run on?

When deploying an existing Xamarin forms proj from Visual Studio I was getting errors like "Failed to load AOT module ‘System.Net.Http’ while running in aot-only mode". This had worked in the past, it seemed Xcode had recently updated before I hit the problem. I found I was able to get the project deploying by changing the csproj entry 10.0 to 10.3. It looks like I could change this setting and everyone would be ok if they also had updated xcode.
My concern is: Does this change what versions of iOS the application can support? Would it have any other surprises when deployed to the apple store?
One thing I don't understand is I am the only person seeing this issue. Another developer is able to deploy to an iOS device (iPad instead of an iPhone) that also has the latest version of iOS without problems. Running “xcodebuild -version” shows we have the same version of xcode installed (8.3.1) and running “xcodebuild -showsdks” shows we have the same iOS sdk available (iOS 10.3).
There is some good documentation on the iOS SDK version: https://developer.apple.com/library/content/documentation/DeveloperTools/Conceptual/cross_development/Overview/overview.html#//apple_ref/doc/uid/20002001-BABEBGCF
You can build against a higher version of the SDK and run against lower versions of iOS.
Building against different versions of the iOS SDK can cause differences in behavior, these may show as regressions in your application.

Need help Android and iOS-App developed on Xamarin

Need some help on xamarin Platform. I understand it can be used to develop Android-base and iOS-base App on Xamarin. I have the following questions:
For Android and iOS-based app develop on Xamarin, can the app run on Android-tablet ad iOS-tablet respectively? what I need to do for both tablets respectively?
If there are new controls for android and iOS, how Xamarin will update this for development?
1) Yes they can run on Android Tablet and iPad. Your code logic would remain the same but you would need to provide for the UI since the resolutions are different.
For iOS, Xamarin makes it simple by providing for a Universal template which allows you to provide different layouts for iPhone & iPad.
For Android, there is no template as such but the process remains the same just as you would for phones with different resolutions.
2) Assuming you are talking about the default controls, they will made available in the Xamarin framework via their regular update channels. First they are in Alpha, then in Beta and once the bugs have been ironed out, they are made available to Stable channel which can then be used in the production apps safely.
I would recommend you go through their docs which are quite good and explains this whole thing in quite detail. Xamarin Docs

AsyncBridge.portable for Xamarin.ios

I created application with mvvmcross and I want to target WPF, andoid and ios.
I used task and async/await in my core PCL library.
It works with WPF and Android because I use Microsoft.Bcl.Async and AsyncBridge.Portable from Daniel Plaisted.
My problem is with ios version because Daniel not implemented AsyncBridge.Portable for ios.
I would like to know if someone maked it or if someone know where I can find source code of AsyncBridge.Portable of Daniel ?
If Daniel, you sees this post, can you explained me how can I make ios version ? :)
Thank you
You can find the source code here. From that, you may be able to just adapt the Android code to work on iOS.
However, official Xamarin PCL support is coming soon (-ish), and that may change how you need to do this (or make it so you don't need to do it at all).

Layer SetNeedsDisplay issue in iOS 4.0

I am working on PDF viewer on iOS, calling [TiledLayer setNeedsDisplay] invalidates display region well in iOS 3.X version. The same code doesn't work on iOS 4.0 onwards. I searched thru forum, None of them helped me.
Could anyone point some clue to resolve this issue?
