Building an AR Clock using SwiftUI and SOLID Design Principles
Augmented Reality (AR) technology merges the virtual world with the real world to create immersive experiences. In this article, we’ll use AR to create a clock, using the Swift programming language and the RealityKit and ARKit frameworks, while implementing SOLID design principles to establish a scalable and maintainable codebase.
SOLID is an acronym for a set of design principles that helps create maintainable and scalable software. These principles include the Single Responsibility Principle (SRP), Open/Closed Principle (OCP), Liskov Substitution Principle (LSP), Interface Segregation Principle (ISP), and Dependency Inversion Principle (DIP).
In order to demonstrate the process of integrating a 3D clock model into an ARKit app, a clock has been designed using Adobe Dimension and the Reality Composer app. The clock has been exported to a .rcproject file for easy integration into the app.
We will create a new subclass of AnchorEntity named ClockAnchor, which will serve as a container for the three hands of the clock, namely the hour hand, minute hand, and second hand. In Reality Composer, each hand is given a unique…
