Introduction The next hurdle to cross when considering KMM is networking. This means we will need to ditch retrofit in favour of Ktor, and if you haven’t already RxJava in favour of Coroutines.

To practically look at this, I’ve taken a small sample of json from the Sky News app feed and deserialised it using Moshi.
