"Build your personal CARD" leverages plenty of exciting Apple technologies to provide its users with a fun, yet easy to understand, experience in which they build their fancy, digital and interactive personal card with a ton of crazy and entertaining interactions and easter eggs. As they progress through this short playground, its users learn the basics of Foundation's data types, the use of DateFormatter objects and how to make use of image literals inside of their code.
To realize my idea, I've utilized many of Apple's powerful features and frameworks:
- Firstly, Swift Playground's APIs have been used to their fullest potential, allowing the user to interact with his creation in real time while modifying the code on the left side thanks to the PlaygroundLiveViewable and PlaygroundRemoteLiveViewProxyDelegate protocols. Input information is transferred seamlessly to the LiveView and doesn't interrupt the experience. User assessment encourages viewers and aids them with hints to help make choices.
- Secondly, the LiveView itself uses Auto Layout to move around and scale its contents: Stack Views make the positioning of buttons easier, and Constraints gave me precise control over what specifically the user sees.
- Additionally, CardView's pan & snap interaction was built using UIKit Dynamics and gesture recognizers. The result is a delightful and fun, physics- and spring-based experience, especially once paired with the appearing message on the last page.
- Furthermore, Core Graphics and Core Animation were used to back CardView's gradient layer leading to sharp colors and efficient rendering.
- Since Accessibility shall always be a top-priority in tech, AVFoundation enables the "Read it out" button that creates a readable version of the card and its interactive elements, e.g., the birthdate ActionView and reads it out.
- Lastly, rounding up the experience, is the user's ability to preview his card in the real world using ARKit and SceneKit. "Build your personal CARD" uses ARKits plane anchors to continuously update its perception of the world and place the card plane onto real objects like tables, chairs or stairs. The new auto lighting feature is used to its fullest potential to simulate a real texture on the card.
All in all, my Swift playground demonstrates how one can use many Apple technologies to create a fun and interactive experience that can be shared by everyone and played with at your own pace.
