A playground is an interactive Swift coding environment that evaluates each statement and displays results as updates are made, without the need to create a project.
Use playgrounds to learn and explore Swift, prototype parts of your app, and create learning environments for others. The interactive Swift environment lets you experiment with algorithms, explore system APIs, and even create custom views.
Share your learning with others by adding notes and guidance using rich comments. Create an explorable learning environment by grouping related concepts into pages and adding navigation.
