Strings are everywhere–you’re looking at one right now. As iOS developers, we rely on Swift Strings every day but don’t give them much thought. This talk will delve into String, with a particular focus on everybody’s favorite type of string–emoji. It will answer questions you’ve always had, like what encoding is and what Unicode and code points are. It’ll show you how to support custom emoji a la Slack and megamoji (BIIIIIIG emoji) in your app.
