GraphQL is an open-source data query and manipulation language for APIs, and a runtime for fulfilling queries with existing data. GraphQL is gaining popularity at a very fast pace and more and more companies are exposing their data using GraphQL. Some are even saying that GraphQL is the new REST and in a span of few years, it will become the default way for implementing APIs.

Check out the contents of the course:

Understanding GraphQL

In this section, you will learn the concepts behind GraphQL technology and how it is different from REST. You will learn about queries, mutations, fragments and subscriptions.

Countries App

In this section, you will learn how to consume Countries GraphQL API. You will learn how to integrate the Apollo framework with your iOS application, download schema, generate models and then finally display them in your SwiftUI application.

Understanding MVVM Design Pattern

In this section, you will learn the concepts behind the MVVM Design Pattern. You will learn the purpose of each component and how it fits in with the MVVM pattern.

Countries App - Building Using MVVM Pattern

In this section, you will revisit the Countries App and reimplement it using the principles of MVVM Design Pattern. You will learn how to implement container view models, read only view models in SwiftUI application.

Weather App

In this section, you will learn how to implement a Weather App in SwiftUI using GraphQL weather API. You will also implement the city search capability, which will allow you to search weather for a city by name.
