GraphQL is an alternative to the commonly used REST API approach. When using [GraphQL](https://graphql.org/) you only get one single endpoint to the server and through that endpoint you need to specify the exact data you need. It was created by Facebook in 2012 and open-sourced in 2015. Using GraphQL in your Swift applications is not that hard. The easiest way is to use [Apollo iOS](https://github.com/apollographql/apollo-ios) client which recently has seen a lot of great improvements and bug fixes. Apollo iOS is a strongly-typed, caching GraphQL client for iOS, macOS, iPadOS, watchOS, and tvOS. It is written in Swift programming language.

Websockets in iOS 13, macOS 10.15, tvOS 13, watchOS 6 and Mac Catalyst have gained first-class citizen status in networking stack. Apple has finally added support in [URLSession](https://developer.apple.com/documentation/foundation/urlsessionwebsockettask) and for lower level in [Network.framework](https://developer.apple.com/documentation/network/nwprotocolwebsocket) for their platforms. This time we will focus on implementing Websockets using URLSession capabilities.
