Here is an example snippet of the theme configuration commands (place these at the top of your Markdown file):

theme: Work
text: Gill Sans, #F5E5C0, text-scale(0.75), line-height(1.4)
header: Gill Sans UltraBold, text-scale(1.2), line-height(0.9)

Xcode unofficial (and undocumented) theme support

Most people is familiar with Xcode theme support for the text editor. You simply open Preferences, Fonts & Colors and duplicate an existing theme (or create a new one from scratch). Xcode editor themes have the .dvtcolortheme extension.

However, there's some support for themeing Xcode itself (fonts, gradients, colors). Xcode loads the default theme from /Applications/Xcode.app/Contents/SharedFrameworks/DVTKit.framework/Versions/A/Resources/Default.dvttheme.

.dvttheme files are simply XML files that conform to an undocumented schema. If you want to modify any of the settings in Default.dvttheme, instead of modifying the bundle resource file you can instruct Xcode to load your custom .dvttheme from wherever you want:

iOS Cell Registration & Reusing with Swift Protocol Extensions and Generics

A common task when developing iOS apps is to register custom cell subclasses for both UITableView and UICollectionView. Well, that is if you don’t use Storyboards, of course.

Both UITableView and UICollectionView offer a similar API to register custom cell classes:

public func register(_ cellClass: AnyClass?, forCellReuseIdentifier identifier: String)
public func register(_ nib: UINib?, forCellReuseIdentifier identifier: String)

Purpose of this list is to gather a source of information on how many people are working on iOS application.
I often wonder how many people are behind Facebook's app or Twitter's. If you're as curious as me, please share and please add apps 😉.
