Associate

Description

This set of methods helps to reduce an amount of a boilerplate code when working with Associated Objects.

Installation

You can add Associate to an Xcode project by adding it as a package dependency.

From the File menu, select Add Packages...

Enter "https://github.com/wowbroforce/Associate" into the package repository URL text field and than add Associate directly to your application.

        set {
            return associate(value: newValue, with: self, by: &textColorNameKey)
        }
