Apple developer documentation

developer.apple.com pages are rendered with JavaScript, so fetch them as Markdown instead. For /documentation pages, add .md to the URL (https://developer.apple.com/documentation/swiftui/view.md). For /design and /tutorials pages, also insert /tutorials/data before the path (https://developer.apple.com/tutorials/data/design/human-interface-guidelines/buttons.md). A few tutorial pages, such as overviews, have no Markdown version; for those, use .json in place of .md (https://developer.apple.com/tutorials/data/tutorials/swiftui.json).
