ThemeManager supports CocoaPods and Carthage. ThemeManager is written in Swift.

CocoaPods is a dependency manager for Cocoa projects. For usage and installation instructions, visit their website. To integrate ThemeManager into your Xcode project using CocoaPods, specify it in your Podfile:

Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks. To integrate ThemeManager into your Xcode project using Carthage, specify it in your Cartfile:

Swift Package Manager

The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the swift compiler. It is in early development, but ThemeManager does support its use on supported platforms.

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

dependencies: [
    .package(url: "https://github.com/azone/ThemeManager.git", from: "0.3.0")
