# Setup

You're viewing documentation for a previous version of this software. Switch to the latest stable version

In this guide, we will be using Graphiti and setting up Vapor from scratch without using any template.

# Prerequisites

Obviously, Pioneer requires Swift installed. Swift can be installed for most operation systems, just follow the official guide from swift.org

Platform	Toolchain
MacOS	Xcode 13.2
Ubuntu	16.04 18.04 20.04
Windows	Windows 10

# Application

Setup the skeleton of the executable using Swift package manager by running:

swift package init --type executable

# Dependencies

Next, add all three main dependencies: Vapor, Graphiti and of course, Pioneer to your Package.swift.

Package.swift
import PackageDescription

let package = Package(
    dependencies: [
        .package(url: "https://github.com/GraphQLSwift/Graphiti.git", from: "1.0.0"),
        .package(url: "https://github.com/vapor/vapor.git", from: "4.61.1"),
        .package(url: "https://github.com/d-exclaimation/pioneer", from: "0.10.0")
    ],
    targets: [
        .target(
            name: "...",
            dependencies: [
                .product(name: "Pioneer", package: "pioneer"),
                .product(name: "Graphiti", package: "Graphiti"),
                .product(name: "Vapor", package: "vapor")
            ]
        )
    ]
)

Swift 5.5 toolchain

Pioneer require Swift 5.5 or up due to the _Concurrency package and features it relies on.

Specifying requirement for Swift 5.5
let package = Package(
    platforms: [
        .macOS(.v12)
    ],
)

At least until Xcode 13.2 is fully fleshed out, where these features are being brought to older versions as well.

# Basic application

Let's continue with setting up the basic Vapor application.

Go to your main.swift, add Vapor, and setup a simple Vapor application with no routing or any other configuration.

main.swift
import Vapor

let app = try Application(.detect())

defer {
    app.shutdown()
}

try app.run()
