With posters and invitations written in Apple Inc's Swift code typography unveiled ahead of its annual developers' extravaganza, the Cupertino, California-based company has already indicated that teaching coding to younger generations will feature at this year's worldwide developers conference.

Apple introduced a new app on Monday named Swift Playgrounds for iPad that helps users learn and explore coding in Swift, the same language used to create apps for the App Store.

Swift Playgrounds includes Apple-developed programming lessons where students write code to guide on-screen characters through an immersive graphical world, solving puzzles and mastering challenges as they learn core coding concepts.
