Operation is not supported on this platform. Xamarin Forms iOS

[kevinvella]

Hi,

I was trying the PureSocketCluster library. Internally it uses Utf8Json. When i run it on iOS it gives me an Operation is not supported on this platform.

Running it on Xamarin.Android it works very well.

Versions: Utf8Json - v1.3.7 Xamarin Forms - v2.5.1.444934

Hope this can help Attaching some screenshots of the stack trace

for iOS, required precode generation. see: https://github.com/neuecc/Utf8Json#pre-code-generationunityxamarin-supports

@neuecc Ok. One question. How should i generate the resolvers for PureSocketCluster?

[neuecc]

related to https://github.com/Coinigy/PureSocketCluster/issues/8 ? It seems to serialize Dictionary<string, object>. https://github.com/Coinigy/PureSocketCluster/blob/master/src/PureSocketCluster/PureSocketClusterSocket.cs

I think configure and use include PrimitiveObjectFormatter, maybe works.

Yes i created an issue on their repo.

I am trying to get the universal code generator to work / figuring it out.

For the PrimitiveObjectFormatter, you saying something like this?

Utf8Json.Resolvers.CompositeResolver.RegisterAndSetAsDefault(
      // use generated resolver first, and combine many other generated/custom resolvers
      Utf8Json.Resolvers.DynamicCompositeResolver.Create(
            new Utf8Json.IJsonFormatter[] { PrimitiveObjectFormatter.Default  }
            ,new Utf8Json.IJsonFormatterResolver[] { Utf8Json.Resolvers.StandardResolver.Default }
      )
);

[kevinvella]

If i use Utf8Json.Resolvers.CompositeResolver.RegisterAndSetAsDefault(new Utf8Json.IJsonFormatter[] { PrimitiveObjectFormatter.Default });

I get this

[neuecc]

You can set like following.

Utf8Json.Resolvers.CompositeResolver.RegisterAndSetAsDefault(
    new [] { PrimitiveObjectFormatter.Default },
    new [] { Utf8Json.Resolvers.StandardResolver.Default }
);

[kevinvella]

Using the above i get the same platform not support exception.

The type initializer for 'Utf8Json.Resolvers.Internal.DynamicObjectResolverAllowPrivateFalseExcludeNullFalseNameMutateOriginal' threw an exception.

Will continue trying to work out the universal code generator

[neuecc]

How about this?

Utf8Json.Resolvers.CompositeResolver.RegisterAndSetAsDefault(
    new [] { PrimitiveObjectFormatter.Default },
    new Utf8Json.IJsonFormatterResolver[] 
    {
        // + code generator resolver(serialize custom type)

        Utf8Json.Resolvers.BuiltinResolver.Instance,
        // EnumResolver.Default,(can't serialize enum...)
        Utf8Json.Resolvers.DynamicGenericResolver.Instance,
        Utf8Json.Resolvers.AttributeFormatterResolver.Instance
    }
);

beat me to it

I will externalize the deserializer interface to allow modifications

[kevinvella]

Holy cow. This works! :D :D

Receiving data from the websocket. Will try to send data shortly.

Thanks very much for this!!! I'm in your debt hahaha
