Using CPDesignPatterns

Including it in your project

Swift Package Manager

To include CPDesignPatterns into a Swift Package Manager package, add it to the dependencies attribute defined in your Package.swift file. You can select the version using the majorVersion and minor parameters. For example:

    dependencies: [
        .Package(url: "https://github.com/catalinpatrascu/CPDesignPatterns.git", majorVersion: <majorVersion>, minor: <minor>)
    ]

Usages Examples

The following examples shows how to use it:

    }
