Allows combining multiple view styles in Swift

Style.swift

struct Style<View: UIView> {

    let styles: [(View) -> Void]

    init(_ style: @escaping (View) -> Void) {
        self.styles = [style]
    }

    init(_ styles: [(View) -> Void]) {
        self.styles = styles
    }

    func apply(to view: View) {
        styles.forEach { $0(view) }
    }
}

func +<View>(left: Style<View>, right: Style<View>) -> Style<View> {
    var styles = left.styles
    styles.append(contentsOf: right.styles)
    return Style(styles)
}
