I've just opened up an 8th Wall project that worked previously and now I'm getting error in initiailisation:

I ended up rebuilding the application from scratch while omitting my personal XR prefabs and scripts and that fixed it. I don't know exactly what is the issue but I suspect it is my attempt to make the wrap the XRController with a singleton for easier access.
Important Tip: When you're making changes and messing with a fragile black box system like XR, be careful and test your app with every iteration.

I have tried a lot of combination to test the code in LoadData function.
The first time the Page loaded, the LoadData function got called. Later user change the date which causing the LoadData function to be called again. This time there was an error quoted below. If I commented the Collection = programs line, the code have no problem.
The problem even if the programs has 0 item in the second execution of the function.
public async Task LoadData (DateTime day)
{
this.day = day;
var programs = await new ECEProgramLogic().GetGrouppedProgram(day.Date, actionNameType);
Collection = programs;
}
private ObservableCollection<GroupViewModel<object>> collection;
public ObservableCollection<GroupViewModel<object>> Collection
{
get
{
return collection;
}
set
{
collection = value;
Banner = new NoDataBannerViewModel<GroupViewModel<object>>(value, AppResources.NoDataToShow);
OnPropertyChanged(nameof(Collection));
}
}
Specified argument was out of the range of valid values. Parameter

It was an issue of the updated Xamarin.Forms 2.51444934. It happened when doing a groupped listview. In order to solve:
ListView.HasUnevenRows = false;
ListView.IsGroupingEnabled = false;
((ObservableCollection<T>)listView.ItemsSource).Clear();
ListView.HasUnevenRows = true;
ListView.IsGroupingEnabled = true;
Put similar code before replacing new data collection. The problem will be solved.
Adding those lines to listview properties works for me.
IsGroupingEnabled="false"
CachingStrategy="RecycleElement"
I am trying to write an MvvmCross app using StoryBoards. I know there are similar questions, but I have followed the solutions and I cannot get it to work. I have referenced one of the solutions I have tried in this question.
I'll explain what I have done from the beginning, hopefully this will help in the diagnosis of my problem
Create a project using the the Universal iOS Single View App in Visual Studio.
I do the standard MvvmCross setup, adding nuget, updating AppDelegate etc.
I get it to compile.
I add a new ViewController to the iPhone storyboard. I call it LogonViewController. I set the Class, Storyboard ID and Restoration ID to LogonViewController. The LogonViewController class is generated. I change it to derive it from MvxViewController
I move the entry arrow from the RootViewController (the view controller on the storyboard when it was initially created) to point to the LogonViewController. I leave the RootViewController on the storyboard
I Change the LogonViewController class to derive from MvxViewController and set the Register attribute to LogonView eg
[Register ("LogonView")]
partial class LogonViewController
I add a label to the LogonViewController just as something to display.
I create a custom container derived from MvxTouchViewsContainers as per the post in
MVVMCross support for Xamarin.iOS Storyboards
The problem is that when the overridden method (shown below) is called in the custom container I get An invalid cast exception as it cannot cast a UIKit.UIViewController to a IMvxTouchView
I also get an arithmetic overflow exception
protected override IMvxTouchView CreateViewOfType(Type viewType, MvxViewModelRequest request)
{
return (IMvxTouchView)UIStoryboard.FromName("MyStoryBoard", null)
.InstantiateViewController(viewType.Name);
}
In the trace log I get the following errors

I took EShy's advice and added the controller and named it LogonView, however I still get a problem where the LogonViewModel is not getting contructed. The log is shown below. Any ideas?

You should name your viewcontroller in the storyboard LogonView and not LogonViewController. That's the viewType.Name that MvvmCross is looking for.
The problem was that a service injected into the LogonViewModel used the MvvmCross Messenger plugin. I had not added the plugin via nuget to the project. The exception that informed me of this was an inner exception of an inner exception. I should have dug deeper. Thanks again to you Stuart for this help and MvvmCross goodness in general. Thanks also to EShy for the naming help.

Seems to be the problem is in one (or more) of referenced in Microsoft.AspNet.Mvc.* assemblies. This is disassemble of DefaultAssemblyProvider from Microsoft.AspNet.Mvc.Core. I guess the problem is in ILibraryManager's implementations GetReferencingLibraries() method. But I can't find this implementation.
public class DefaultAssemblyProvider : IAssemblyProvider
{
private static readonly HashSet<string> _mvcAssemblyList;
private readonly ILibraryManager _libraryManager;
public IEnumerable<Assembly> CandidateAssemblies
{
get
{
return Enumerable.Select<AssemblyName, Assembly>(Enumerable.SelectMany<ILibraryInformation, AssemblyName>(this.GetCandidateLibraries(), DefaultAssemblyProvider.\u003C\u003Ec__DisplayClass0.CS\u0024\u003C\u003E9__CachedAnonymousMethodDelegate2 ??

I had a similar problem on Windows and found the wrong KRE was active.
Executing kvm list shows a list of KRE. In my case the 1.0.0-alpha4 version was active instead of the more recent beta version.
Switching to the default with kvm use default sorted it out for me.
I was able to resolve this error by updating my version of KVM, there is probably a simpler way but, assuming you initially installed using homebrew, running these commands should solve your issue
brew untap aspnet/k
brew tap aspnet/k
brew install kvm
then you should be able to run k kestrel
if you get a message that kvm is already installed then:
brew link --overwrite mono
brew uninstall mono
brew reinstall kvm
I use MvvmCross for develop a CrossPlatform App.
I work on my Mac and I have not errors when I build my solution.
When I run it... I have this error : failed to find constructor for type Cirrious.MvvmCross.ViewModels.MvxViewModelLoader and highlights base.ViewDidLoad();
Code :
public partial class MainView : MvxViewController
{
static bool UserInterfaceIdiomIsPhone {
get { return UIDevice.CurrentDevice.UserInterfaceIdiom == UIUserInterfaceIdiom.Phone; }
}
public MainView ()
: base (UserInterfaceIdiomIsPhone ? "MainView_iPhone" : "MainView_iPad", null)
{
}
public override void DidReceiveMemoryWarning ()
{
// Releases the view if it doesn't have a superview.
base.DidReceiveMemoryWarning ();
// Release any cached data, images, etc that aren't in use.
}
public override void ViewDidLoad ()
{
base.ViewDidLoad ();
// Perform any additional setup after loading the view, typically from a nib.
}
It's a default code, I just changed super-class (UIViewController to MvxViewController)

Failed to find constructor for type Cirrious.MvvmCross.ViewModels.MvxViewModelLoader
From the stack trace, I'm guessing the line that is failing is: https://github.com/MvvmCross/MvvmCross/blob/v3.1/Cirrious/Cirrious.MvvmCross.Touch/Views/MvxViewControllerExtensionMethods.cs#L44
This is looking in IoC for a type which has been registered in setup as:
protected virtual void InitializeViewModelFramework()
{
Mvx.RegisterType<IMvxViewModelLoader, MvxViewModelLoader>();
}
(from https://github.com/MvvmCross/MvvmCross/blob/v3.1/Cirrious/Cirrious.MvvmCross/Platform/MvxSetup.cs#L192)
Looking at MvxViewModelLoader, this is defined in: https://github.com/MvvmCross/MvvmCross/blob/v3.1/Cirrious/Cirrious.MvvmCross/ViewModels/MvxViewModelLoader.cs - so it should have a default public parameterless constructor added by the compiler...
With this in mind...
I'm guessing that maybe Xamarin is stripping out the constructor from your deployed binaries. This might be because of your linker settings - so please check that you have set the linker to link "SDK only". But if that doesn't help then this might be down to some Xamarin optimisation/feature - so you might need to .
As a simple workaround you could try overriding Setup so that you use:
protected override void InitializeViewModelFramework()
{
Mvx.RegisterSingleton<IMvxViewModelLoader>(() => new MvxViewModelLoader>());
}
However, even if this works, then I'd be worried that the linker might be stripping out other symbols in your app - so this might not be enough... you might need to chase this through with Xamarin.

From other answers I found that there might be a problem with accessors but I don't find
(void)get
or
(void)set
in my code. Help!
