Provides Xcode-free iOS development workflows using xtool — build SwiftPM iOS apps on Linux, Windows, and macOS without Xcode. Use when building iOS apps with xtool, creating new xtool projects, adding app extensions (widget, share, keyboard, Safari, action), configuring xtool.yml, running xtool dev/auth commands, or evaluating xtool vs XcodeGen/Tuist; also triggers on iOS development on Linux or Windows.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Using xtool

## Overview

xtool is a **cross-platform Xcode replacement** for building iOS apps with SwiftPM on Linux, Windows, and macOS. It is NOT XcodeGen, Tuist, or Xcode project files.

## Critical: xtool is NOT XcodeGen

| xtool Uses | NOT These |
|------------|-----------|
| `xtool.yml` | `project.yml`, `Project.swift` |
| `Package.swift` (SwiftPM) | Xcode project files |
| `xtool dev` | `xtool build`, `xtool run`, `xtool generate` |
| `Sources/` directory | `Extensions/` directory |

## Project Structure

```
MyApp/
├── Package.swift          # SwiftPM package definition
├── xtool.yml              # xtool configuration
├── Sources/
│   ├── MyApp/             # Main app target
│   │   ├── MyAppApp.swift
│   │   └── ContentView.swift
│   └── MyWidget/          # Extension target (if any)
│       └── Widget.swift
├── MyApp-Info.plist       # Optional custom Info.plist
└── MyWidget-Info.plist    # Required for extensions
```

## Quick Reference: Commands

```bash
# Project lifecycle
xtool new MyApp              # Create new project
xtool new MyApp --skip-setup # Create without running setup
xtool dev                    # Build + run (same as `xtool dev run`)

How to install

The exact contents, by fingerprint
mdr add 2389-research/xtool/using-xtool@sha256:87b7e4f52faca6ca

The line at the top of this page pins the label git:20260706.9675ecf, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
