Checking out the code in the docs may give you an idea how you can use the library. On the other hand, it might still feal strange to actually start using it in your project. This guide aims to give you an idea of how to structure your code and files depending on your needs.
These are examples of what we’ve seen in the wild. Feel free and try other options and share them with us!

Model Bound Queries

Queries extend Swift model as static constants.
We usually start the project by creating a GraphQL folder in the root folder of our project. Then, we generate the API.swift file inside GraphQL folder and add Scalars, Query, Mutation and Subscription folders if needed. To prevent any naming collisions we create custom queries in files that follow the pattern of <structure><action> (e.g. HumanQuery.swift or HumanSubscription.swift). This leaves us with a tree structure resembling
  • GraphQL
    • API.swift
    • Scalars
      • DateTime.swift
      • URL.swift
    • Query
      • HumanQuery.swift
      • CharacterQuery.swift
    • Mutation
      • AuthMutation.swift
    • Subscription
      • TimeSubscription.swift
Inside each query file we follow the principle that queries should extend the referenced struture as static constants. Additionally, we follow the naming convention that
  • “regular mappings” use selection variable, and
  • methods on root types (i.e. query, mutation and subscription) should be called query and mutation and subscription respectively.
extension Human {
	/// Converts an API Human type into app model.
	static let selection = Selection.Human<Human> {
		Human(
			id: try $0.id(),
			name: try $0.name()
		)
	}

	/// Obtains a Human with a given ID from the server.
	static func query(id: String) -> Selection.Query<Human?> {
		let query = Selection.Query<Human> {
			try $0.human(id: id, selection: Human.selection)
		}

		return query.nullable
	}
}

View Bound Queries

Queries extend SwiftUI views as static variables.
Each SwiftUI component that relies on GraphQL data exports a query as a static value that can be used to obtain the data. Parent components then hoist selections from their children and create a query request to the server.
