With.swift - A chainable, storable, composable configuration object featuring Swift keypaths

Based on some source I don't exactly remember right now but will add a link to later.

// When used on instances, allows changing fields directly using keypaths (handy way to avoid 'lazy var' property closures!)
let label
    = UILabel()
        .with(\.text, setTo: "Hello!")
        .with(\.textColor, setTo: UIColor.darkGray)
