- Kulve is a SwiftUI application leveraging Swift/C++ interop introduced with Swift 5.9.
- The tech stack includes CMake, Xcode, VSCode, Swift/SwiftUI, and C++.
- CMake is used for independent C++ backend development, ensuring cross-platform compatibility.
- Xcode is utilized for SwiftUI editing and as a build system, despite preferring VSCode for raw editing.
- VSCode, with the clangd extension, is used for backend C++ development, offering superior linting and auto-complete.
- Swift is used exclusively for UI and scaffolding, while C++ handles general-purpose tasks like threading and networking.
- The application uses Swift/C++ interop for features like chat, with C++ managing memory and Swift handling UI updates.
- Memory management is handled in C++, with Swift wrapping raw pointers to ensure safety and efficiency.
- The design ensures Swift does not own memory, preventing leaks and maintaining performance.
- Kulve's approach allows embedding large data structures in UI elements efficiently via pointers.
- The post highlights unique solutions developed for Kulve, aiming to inform and assist others in native SwiftUI development.
