SystemKit

A macOS system library in Swift based off of libtop, from Apple's top implementation.

• For an example usage of this library, see dshb, a macOS system monitor in Swift
• For other system related statistics in Swift for macOS, see SMCKit

Build

• Xcode 14.2
• Swift 5
• macOS Monterey 12.6.5

Installation

Swift Package Manager

The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the swift compiler.

Once you have your Swift package set up, adding Alamofire as a dependency is as easy as adding it to the dependencies value of your Package.swift.

dependencies: [
    .package(url: "https://github.com/awkx/SystemKit.git", .upToNextMajor(from: "0.0.6"))
]

Carthage

Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.

You can install Carthage with Homebrew using the following command:

$ brew update
$ brew install carthage

To integrate SystemKit into your Xcode project using Carhage, specify it in your Cartfile:

github "awkx/SystemKit"

Run carthage update to build the framework and drag the built SystemKit.framework into your Xcode project. Don't forget to alter your Carthage building phase for macOS.

Example
