How to make your own custom ViewDecorator?

You can extened decorators with extension for ViewDecorator struct for implementing your own design system (learn what is design system). In example:

import DonaCore

extension DonaViewDecorator {
    static var largeTitle: DonaViewDecorator<UILabel> {
        DonaViewDecorator<UILabel> {
            $0.decorated(with: .disabledAutoresizingMask())
                .decorated(with: .font(.systemFont(ofSize: 29, weight: .bold)))
                .decorated(with: .textColor(.primary))
                .decorated(with: .numberOfLines(0))
        }
    }
}

After combining or creating new decorators you can use it as usual:

private let titleLabel = UILabel()
    .decorated(with: .text("Welcome 👋"))
    .decorated(with: .largeTitle)
