Creating an Application with Vision OS, Swift UI, and Reality Kit

Overview

• Focus: Building an application from scratch using Vision OS SDK, Swift UI, Reality Kit, and Reality Composer Pro.
• Key points: Setting layouts, handling audio for 3D models.

Setup in Xcode

• Start a new project:
  • Select Vision OS tab.
  • Choose a product name, e.g., "Inspiration for App" (related to SpaceX).
  • Ensure bundle identifier is unique for future app uploading.
  • Set initial settings (e.g., render using Reality Kit).
• Choose immersive experience settings (Full VR vs. Mixed Reality).

Navigating Xcode

• Preview functionality allows changes to be seen in real time.
• New files can be created for Swift UI Views to manage navigation components.
• Organizing files into groups (e.g., "Areas" for mission details, crew, and equipment).

Swift UI Basics

• Main app structure consists of a struct with body logic for window styles, immersive experiences, and navigation.
• Example: Creating a view for "Areas" to push different windows in Z-space.
• Use horizontal (HStack), vertical (VStack), and z-axis layouts for navigation.

Creating Views and Models

• Create enums to define areas (astronauts, equipment, missions).
• Utilize identifiable, equatable, and Codable protocols for better object management.
• Create a view model class to manage navigation paths through Observable properties.
• Implement Swift UI views following modular patterns for scalability.

Adding Navigation

• Create a NavigationLink and connect it to various components (e.g., crew, equipment, missions).
• Set design properties using modifiers for better aesthetics (font size, weight, padding).

Reality Kit Integration

• Import Reality Kit for handling immersive content.
• Use RealityView for rendering scenes, loading assets through Reality Composer Pro.
• Manage different types of windows (e.g., volumetric, immersive).
• Setup features like toggles to control visibility and interactions with 3D models.

Sound and Audio Management

• Use Audio Playback Controller for managing background audio sounds.
• Implement audio elements paired with immersive experiences to enhance usability.

Testing the Application

• Test the application on a simulator to ensure the flow works as intended.
• Utilize errors for learning and debugging.

Conclusion

• Encourage feedback and questions in comments for future content.
• Emphasize the learning curve while getting familiar with Swift, Swift UI, and Reality Kit concepts.
