Json . NET, iOS and AOT

Questions & Answers
1

Have anyone managed to get Json . NET (Newtonsoft JSON library) to work with Unity on iOS?

When I try to deserialize my VostopiaSkinnedMesh class my data on iOS, I get the dreaded

System.ExecutionEngineException: Attempting to JIT compile method 
'(wrapper dynamic-method) VostopiaSkinnedMesh:CreateVostopiaSkinnedMesh ()'
while running with --aot-only.

Others have reported to get Json . NET working with MonoTouch, but I don’t know what, if any, differences there are with the mono touch AOT approach to the Unity AOT aproach?

I’ve tried the usual, making sure my constructor isn’t omitted by the AOT compiler by making explicit calls to it, but the AOT compiler doesn’t want to play. Any suggestions?

cheers,

Are you using an AOT version of Json.Net? The dll needs to be compiled with AOT in mind. If you want it to just work there is a specific Unity version of Json.NET Unity Asset Store - The Best Assets for Game Making

It compiles based on your build target and professes to work on iOS, I haven’t tried iOS it yet.
