**vorssaint-utils is written primarily in Swift**, packaged as a native macOS utility suite using Swift Package Manager and targeting macOS 14 and later.

The open-source repository `vorssaint/vorssaint-utils` provides system-level utilities for macOS users. When investigating this codebase, developers frequently ask what programming language powers the implementation. The answer is Swift, Apple’s modern systems programming language, which drives the entire runtime application alongside auxiliary Bash scripts for build automation.

## Swift Package Structure and Configuration

The vorssaint-utils programming language is definitively Swift. The project adheres to standard Swift Package Manager conventions, with package metadata declared in [`Package.swift`](https://github.com/vorssaint/vorssaint-utils/blob/main/Package.swift) and source files organized under `Sources/Vorssaint/`.

### Package Manifest and Targets

In the repository root, [`Package.swift`](https://github.com/vorssaint/vorssaint-utils/blob/main/Package.swift) defines the Swift package metadata, specifying macOS 14 as the minimum platform target and declaring the `Vorssaint` executable product. This manifest orchestrates compilation using the standard Swift toolchain, linking against macOS system frameworks required for the utility’s functionality.

### Entry Point and Application Lifecycle

The main entry point resides in [`Sources/Vorssaint/main.swift`](https://github.com/vorssaint/vorssaint-utils/blob/main/Sources/Vorssaint/main.swift). This Swift file initializes the macOS application lifecycle using **AppKit**, specifically instantiating `NSApplication.shared` and assigning an `AppDelegate`. It also handles command-line interface (CLI) parsing for flags such as `--selftest`, `--sensors`, and `--uninstall` before conditionally launching the graphical interface or executing utility commands directly.

## Build-Time Auxiliary Scripts

While the runtime binary is pure Swift, the repository includes supporting Bash scripts for development and distribution workflows. These scripts are not embedded in the final executable but facilitate secure deployment.

The [`Tools/setup-signing.sh`](https://github.com/vorssaint/vorssaint-utils/blob/main/Tools/setup-signing.sh) script configures code-signing certificates during the build process, while [`Tools/make-dmg.sh`](https://github.com/vorssaint/vorssaint-utils/blob/main/Tools/make-dmg.sh) assembles the final disk image for distribution. Additionally, the test suite in [`Tests/TestSuite.swift`](https://github.com/vorssaint/vorssaint-utils/blob/main/Tests/TestSuite.swift) contains Swift unit tests exercising core functionality, compiled and executed via `swift test`.

## Building and Running from Source

Since vorssaint-utils is a Swift package, you can compile and execute it using the Swift toolchain without external build systems. The package supports several diagnostic flags for system inspection.

To build and run the utility from the command line:

```bash

# Build and run the executable (requires Swift toolchain)

swift run Vorssaint --selftest   # executes the built‑in self‑test suite

swift run Vorssaint --sensors    # dumps sensor information

swift run Vorssaint --uninstall  # triggers the uninstaller

```

These commands compile the Swift source files in `Sources/Vorssaint/` and execute the resulting binary with the specified runtime flags.

## Embedding vorssaint-utils as a Swift Dependency

Developers can integrate vorssaint-utils into larger Swift projects via Swift Package Manager. The library exposes its functionality through the `Vorssaint` module, allowing programmatic access to its macOS system utilities.

Add the dependency to your [`Package.swift`](https://github.com/vorssaint/vorssaint-utils/blob/main/Package.swift):

```swift
// swift-tools-version:5.9
import PackageDescription

let package = Package(
    name: "MyApp",
    dependencies: [
        .package(url: "https://github.com/vorssaint/vorssaint-utils.git", from: "3.1.4")
    ],
    targets: [
        .executableTarget(
            name: "MyApp",
            dependencies: ["Vorssaint"]
        )
    ]
)

```

After adding the dependency, import the module in your Swift code to leverage the utility functions implemented in the vorssaint-utils source.

## Core Runtime Implementation

The Swift implementation in [`Sources/Vorssaint/main.swift`](https://github.com/vorssaint/vorssaint-utils/blob/main/Sources/Vorssaint/main.swift) demonstrates typical macOS application patterns. The code initializes system guards and services before entering the run loop:

```swift
import AppKit

SuperKeyMappingGuard.runIfRequestedAndExit()
Defaults.register()
MouseAccelerationGuard.runIfRequestedAndExit()
MouseAccelerationService.recoverPendingAtLaunch()

if CommandLine.arguments.contains("--selftest") {
    SelfTest.runAndExit()
}
if CommandLine.arguments.contains("--sensors") {
    SensorDump.runAndExit()
}
if CommandLine.arguments.contains("--uninstall") {
    Uninstaller.runAndExit()
}

let app = NSApplication.shared
let delegate = AppDelegate()
app.delegate = delegate
app.run()

```

This snippet illustrates how the vorssaint-utils programming language handles both CLI-mode execution and full GUI application launch, utilizing Swift's interoperability with Apple's **AppKit** framework.

## Summary

- vorssaint-utils is written in **Swift**, targeting macOS 14+ as a native utility suite.
- The project uses **Swift Package Manager** with [`Package.swift`](https://github.com/vorssaint/vorssaint-utils/blob/main/Package.swift) defining the build configuration and executable targets.
- Core logic resides in [`Sources/Vorssaint/main.swift`](https://github.com/vorssaint/vorssaint-utils/blob/main/Sources/Vorssaint/main.swift), utilizing **AppKit** and `NSApplication` for macOS integration.
- **Bash scripts** in [`Tools/setup-signing.sh`](https://github.com/vorssaint/vorssaint-utils/blob/main/Tools/setup-signing.sh) and [`Tools/make-dmg.sh`](https://github.com/vorssaint/vorssaint-utils/blob/main/Tools/make-dmg.sh) handle auxiliary build tasks like code signing and DMG creation, but the runtime is pure Swift.
- Developers can integrate the package using Swift Package Manager by adding the GitHub repository as a dependency.

## Frequently Asked Questions

### Is vorssaint-utils written entirely in Swift?

The runtime application and test suite are written entirely in Swift, including the main executable logic in `Sources/Vorssaint/` and tests in [`Tests/TestSuite.swift`](https://github.com/vorssaint/vorssaint-utils/blob/main/Tests/TestSuite.swift). However, the repository includes a few Bash scripts located in [`Tools/setup-signing.sh`](https://github.com/vorssaint/vorssaint-utils/blob/main/Tools/setup-signing.sh) and [`Tools/make-dmg.sh`](https://github.com/vorssaint/vorssaint-utils/blob/main/Tools/make-dmg.sh) that handle build-time automation such as code signing and packaging. These scripts do not ship with the final binary.

### What macOS version does vorssaint-utils require?

According to the [`Package.swift`](https://github.com/vorssaint/vorssaint-utils/blob/main/Package.swift) manifest, vorssaint-utils targets **macOS 14** and later. This requirement allows the Swift codebase to leverage modern macOS APIs and frameworks available in recent versions of the operating system.

### Can I use vorssaint-utils as a library in my own project?

Yes. The repository is structured as a Swift package, allowing you to add it as a dependency via Swift Package Manager. You can import the `Vorssaint` module into your own Swift applications to utilize its system utility functions, as demonstrated in the dependency configuration examples.

### How do I build vorssaint-utils from source?

Building requires the Swift toolchain (version 5.9 or later, based on the `swift-tools-version` declaration). Clone the repository and run `swift build` to compile, or use `swift run Vorssaint` with appropriate flags like `--selftest` or `--sensors` to execute specific functions directly from the source without manual compilation steps.
