extension UIFont {

    /// Returns an instance of the font associated with the text style, specified design, and scaled appropriately for the user's selected content size category.
    /// - Parameters:
    ///   - style: The text style for which to return a font. See UIFont.TextStyle for recognized values.
    ///   - weight: The weight of the font, specified as a font weight constant. For a list of possible values, see "Font Weights” in UIFontDescriptor. Avoid passing an arbitrary floating-point number for weight, because a font might not include a variant for every weight.

TL;DR

If you are using the iso8601 strategy, you may not want to rely on the default Equatable implementation for Date (==) when comparing dates. You can use a good old fashion calendar comparison instead.

Strategies

JSONEncoder and JSONDecoder can both be configured with a strategy (dateEncodingStrategy and dateDecodingStrategy) for encoding and decoding dates. There are four named types in addition to allowing you to provide custom options.
