WWDC 2015-2018 Session Videos

For some reason some older WWDC session videos have been disappearing from Fruit Co's the developer site. Luckily Harish posted this this gist of URL's and titles. So I converted that JSON to this markdown doc.

Enjoy!

    /// 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.
    ///   - fontDesign: The new system font design.
    /// - Returns: A font object of the specified style, weight, and design.

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.
