I have a fork where I implemented vendor messages for android. Unfortunately, on iOS, you cannot send/receive generic messages like you can with android. You have to make a class for your vendor models and structs for all the messages which can only be done in the native code as far as I know. I have my vendor model implemented in the fork so you can use that as a reference. I'll try to get around to making a pull request with the android vendor messages soon.
