[Xamarin.Forms.GoogleMaps][1] is failing when deploying to IOS (in my case iPhone phisical device).
The app is trying to start but then crashes to the OS. Visual Studio does not catch the break point.
In the output window I get this:

' The app has been terminated.
First, I tried on my local project. After, I decided to get the source code of the googlemaps libray from git hub and debug it.
It breaks in the MapRenderer.cs
private void UpdateIsShowingUser(bool? initialMyLocationButtonEnabled = null)
{
#pragma warning disable 618
((MapView)Control).MyLocationEnabled = ((Map)Element).IsShowingUser;
((MapView)Control).Settings.MyLocationButton = initialMyLocationButtonEnabled ?? ((Map)Element).IsShowingUser;
#pragma warning restore 618
}
Apparently the native Google.Maps.MapView.Settings is null here. I am not sure what exacly am I doing wrong, but the same library works perfect in Andoid version. It only fails in IOS.
I have set up API keys and API on google developer console.
Visual Studio Version 16.7.7
IOS 14.1
Xamarin.iOS 14.2.0.12
I also tried the standard xamarin google maps lirary and it works fine (it just miss many features comparing to Xamarin.Forms.GoogleMaps)

I'm attempting to add Xamarin.Forms Material Visual to my app. I'm following the instructions here and after I add the Forms Material init, I get a crash in the Forms init. Here's the code...
public override bool FinishedLaunching(UIApplication app, NSDictionary options)
{
global::Xamarin.Forms.Forms.Init();
global::Xamarin.Forms.FormsMaterial.Init();
LoadApplication(new App());
return base.FinishedLaunching(app, options);
}
Without global::Xamarin.Forms.FormsMaterial.Init();, everything runs fine. When I add it, global::Xamarin.Forms.Forms.Init(); crashes with an exception "System.Reflection.CustomAttributeFormatException has been thrown" and "Could not find a property with name Priority". How does a line added after another cause an exception on the previous line? Anyone know what's going on?
Here's the stacktrace:

I am trying to create a mobile application using MvvmCross v.4.4.0.
Application works correct. But if collapse application and lock the phone, and then unlock and press "Overview" android button application crash (only on the Xiaomi phone).
I think android kills activity and then unsuccessfully trying to recreate it.
Could you, please explain me, what I do wrong? How to fix it?

This is a linking issue. You have some kind of DialogProvider, which uses the Android.Text.Html.FromHtml method, which seems to be stripped out.
You can add expressions to LinkerPleaseInclude.cs to prevent the linker from removing code or you can add [Preserve(AllMembers = true)] attribute on your DialogProvider class.
I create the xamarin form project and update the content view content multiple time.
Its correctly update for android. But it not work for iOS
I have update the Contentview content when click the button like that
contentView.content = mVview;

Finally I found the solution in my own way, i think i don't know is this correct way but in my case it work perfectly
I rendererd the list view for ios and overide the methods dispose with try/catch statement
protected override void Dispose()
{
try{
base.Dispose();
}
Catch(Exception ex)
{
return;
}
}
I'm trying to run a simple line in Mono, using Microsoft.CodeAnalysis:
var workspace = MSBuildWorkspace.Create();
But the problem is that it seems that it can't load roslyn libraries because we are using Mono:

But according with this thread, Roslyn was completely integrated into Mono.
Is there any way to get it working on Mono? If yes, how should I do this?
