when building for debug, a .net virtual machine is used, to allow debugging and fast deploy. the Apple Store does not allow virtual machine, so the app must be compiled via AOT. AOT compiles are more restrictive in what code is allowed (no reflection support for example).

In your case NewtonSoft is not supported. you will need the AOT enabled System.Text.Json serializer, and must use the source generation feature:

can you please show how to enabled System.Text.Json serializer, and how to use the source generation feature, in my case is dynamic

dynamic dynamicDictionary = Newtonsoft.Json.JsonConvert.DeserializeObject<dynamic>(resultsJson);

var dic = Newtonsoft.Json.JsonConvert.DeserializeObject<IList<IDictionary<object, object>>>(dynamicDictionary);

Hi Dani_S, it looks like another issue. You determine the issue occurs on the code snippets, right? Could you describe your excepted behavior in detail?

I used System.Text.Json and it works.
