1. Literal Creator For Xcode App

Oct 7, 2015

A 'literal' refers to any value which can be written out directly in source code. For example, 'hello' is a character literal and 32 is a integer literal. In the past Objective-C hasn't had support for defining literals, but as of Xcode 4.5 this is supported. The new syntax is. In Xcode 10 and Swift 4.2, only the code completion function (or auto-complete) of the Xcode IDE has been discontinued for the old way. Here is the new way: Just type image literal and it will complete with default icon. Double click on this icon and it will open the media library right side of it. Just choose your imagem and it work like before! A color literal allows you to select colors using a color picker directly from your code. You can either select a color or type in the HEX code. You can also set the opacity. Note: Color literals are great for static colors. For colors that adapt to dark mode, I suggest using colors in the Assets Catalog.

Literals are the actual values of your data represented in their native format, directly within the Xcode editor. For instance, there’s no need to type “myImage.jpg” in the editor – just drag your image from the Finder and the actual image will appear in-line with your code. Instead of showing RGB values to indicate color, the playground will render a color swatch. Literals in playgrounds behave similarly to code you would otherwise hand-author in regular Swift code, but are rendered in a much more useful manner.

In addition to looking cool, literals can also make editing resources much faster. You can use the color picker to quickly choose a different color from the palette. Drag-and-drop files from the Finder into your playground code to start using them immediately. You can even add a literal at your current cursor position by selecting Editor > Insert File, Image, or Color Literal. Double-clicking a literal allows you to easily choose another value.

Resources are copied into your playground’s resources directory if needed, so everything your playground requires is included within the document. Because literals are part of your code, you can also copy, paste, move, and delete them exactly how you would any source code.

Literals in Swift Code

Literals translate into platform-specific types, the defaults of which are listed below:

To get the full in-line presentation experience of literals, you must be in a playground. However, if you copy and paste code that uses literals into your main Swift source code, the pasted code will work as expected and Xcode will simply render the literals as plain text.

To get you started with literals we’ve included a very short playground in this blog post. Download the latest Xcode 7.1 beta to give this playground a try.

Additional Documentation

Documentation accompanying Xcode 7.1 beta 3 includes an updated playgrounds help document with new information on the many powerful features in playgrounds, including new content on literals. Here are direct links to the relevant sub-pages: Adding Image Literals, Adding Color Literals, and Adding File Literals.
