Tuist is a great tool to manage Swift projects. But I still have to write a lot of codes to config my project. So I decide to share my configuration. SwiftUItemplate is my opionionated configuration for Tuist.

1. create your first project by tuist init --platform ios
2. open Tuist/Config.swift, change it to

import ProjectDescription

let config = Config(
    plugins: [
        .git(url: "https://github.com/haifengkao/SwiftUITemplate", tag: "0.5.0")
    ]
)

3. run tuist fetch in terminal to download SwiftUITemplate

If the above procedure doesn't work, please check Tuist documentation for more info.

SwiftUITemplate follows microfeature architecture.

An app is composed by mutiple microfeatures. Each microfeature contains

• example target to deomstrate the feature
• unit test target to test the feature
• framework codes which implements the feature

A module might be microfeature or a swift package (Cocoapods and Carthage are not supported, PR welcome).

To add a microfeature, create Tuist/ProjectDescriptionHelpers/Modules.swift. Then add the microfeature to modules, e.g.

import ProjectDescription
import SwiftUITemplate
private extension Module {
    static var MyApp: Module {
        .uFeature(name: "MyApp", targets: [
            .exampleApp: .resourcesOnly,
            .unitTests: .default,
            .framework: .default,
        ])
    }
}

public let modules: [Module] = [
    Module.MyApp,
    Module.Quick,
    Module.Nimble,
]

You can specify 4 different kinds of targets:

• .framework the framework codes which other modules can depend on
• .unitTests the unit test target to test the framework
• .exampleApp the example target
• .uiTests the ui test target which will run over example app

TargetConfig has four modes

• .default indicates the target has no resources to include and no dependencies to other modules
• .resourcesOnly indicates the target has resources but no dependencies
• .hasDependencies([Modules]) let you specify the target's dependencies
• .hasResourcesAndDependencies([Modules]) indicates the target has resources and dependencies

By default, SwiftUITemplate uses Nimble and Quick as the unit test framework. It's mandatory to include Nimble and Quick for the unit test placeholder codes to compile

You can specify project name and the targets in Project.swift.

import ProjectDescription
import ProjectDescriptionHelpers
import SwiftUITemplate

let project: Project = Project(name: "MyApp",
                               organizationName: "example.SwiftUITemplate",
                               targets: modules.allProjectTargets)

modules.allProjectTargets tells tuist to include all targets(exampleApp, unit test, frameworks) into the generated project.

To include swift packages, we can create a swift package with .package. The following example adds Alamofire into MyApp's framework traget.

import ProjectDescription
import SwiftUITemplate
private extension Module {
    static var MyApp: Module {
        .uFeature(name: "MyApp", targets: [
            .exampleApp: .resourcesOnly,
            .unitTests: .default,
            .framework: .hasDependencies([
                .Alamofire
            ]),
        ])
    }

    static var Alamofire: Module {
        .package(name: "Alamofire", url: "https://github.com/Alamofire/Alamofire", requirement: .upToNextMajor(from: "5.5.0"))
    }
}

public let modules: [Module] = [
    Module.MyApp,
    Module.Quick,
    Module.Nimble,
]

We don't have to add Module.Alamofire into modules because SwiftUITemplate will automatically find Module.Alamofire in Module.MyApp's dependencies.

Tuist requires us to specify swift packages in Dependencies.swift. So we have to create Tuist/Dependencies.swift with the following content

import ProjectDescription
import ProjectDescriptionHelpers
import SwiftUITemplate

let dependencies = Dependencies(
    swiftPackageManager: .init(
        modules.allSwiftPacakges,
        targetSettings: modules.allTargetSettings
    ),

    platforms: [.iOS]
)

SwiftUITemplate will find out all swift packages defined in modules and its dependencies.

To generate the .xcworkspace

1. run tuist fetch to download swift packages
2. run tuist generate to generate xcworkspace

If the above procedure doesn't work, please check Tuist tutorial for more info.

├── Tuist
│   └── (Tuist setting files)
└── Features
    ├── MyApp
    │	├── Example (example target codes)
    │   ├── Tests  (unit test target codes)
    │	└── Sources (framework codes)
    └── MyFeature1
        ├── Example
        ├── Tests
        └── Sources

All features are located in Features folder. SwiftUITemplate will find corresponding codes and resources in the predefined subfolders.

This plugin provides templates to create a microfeature placeholder files

tuist scaffold ufeature --name MyFeature1 --company TuistDemo

It will create MyFeature1 in Features folder.

I am too lazy to write a complete doc

To start working on the project, you can follow the steps below:

1. Clone the project.
2. cd fixtures/Example1
3. tuist fetch to install the plugin
4. tuist edit to modify the plugin files
5. tuist generate to generate the example xcworkspace. Use this command to check if the plugin works correctly
