Swift on Windows: A Year of Refinement
2 months ago
- Rebuilt the runtime build system with modern CMake to ensure reproducible builds and enable cross-compilation.
- Introduced the Experimental Swift SDK, packaging runtime and core libraries with multiple distribution models including static and side-by-side.
- Implemented static linking of the Swift runtime on Windows, eliminating runtime version mismatches caused by PATH-based DLL discovery.
- Disabled library-evolution mode on Windows to remove unnecessary indirection and reflect the platform's lack of ABI stability.
- Enabled side-by-side runtime deployment through embedded manifests, allowing multiple runtime versions to coexist.
- Validated the new linkage and distribution model with real tools like SwiftFormat, SwiftLint, and developer utilities nv and vigil.
- Improved the Clang Importer to support Windows UNICODE macro aliases, enhancing API fidelity.
- Community contributions, notably from the Swift Testing framework team, improved Windows support for testing infrastructure.

Hot reloading is better than SwiftUI previews
2 months ago
- Hot reloading provides faster iteration than Xcode Previews by dynamically loading code changes without restarting the app.
- The technique uses dynamic libraries (.dylib) and the dlopen/dlsym functions to load and call new code at runtime.
- Swift's name mangling is avoided by exporting functions with @_cdecl, and returning an NSHostingView to bridge SwiftUI and C.
- A host app loads the library, uses NSViewRepresentable to embed the NSView, and periodically checks for file changes via a timer.
- To force dlopen to load the updated library, the file is copied to a new name before each reload.
- State persistence across reloads is achieved by storing the app state in the host and passing it to the library via createState and createStatefulView functions.
- Incompatible state changes between versions may cause crashes; this can be mitigated by versioning the state and resetting when needed.

"Fix" MacBook Neo Cursor Lag: Record 1 Pixel of the Screen Every 10 Seconds
3 months ago
- The script is a Bash script for building a macOS application called 'Unlag Neo'.
- It compiles a Swift program that creates a status bar app to manage screen recording permissions and control screen capture behavior.
- The app monitors for fullscreen windows and can pause screen capture when a fullscreen application is active.
- It handles accessibility permissions and provides UI alerts for missing permissions.
- The app includes menu options to toggle functionality, enable launch at login, and exit.
- The screen capture uses a 1x1 resolution with a 10-second frame interval to keep permissions active.
- The script sets up the app bundle, compiles the Swift code, and opens the app directory upon completion.
Bringing Swift to the Apple ][
3 months ago
- SwiftII is a Swift-like mini development environment for the Apple II, inspired by Apple Pascal's bytecode approach.
- The project targets original Apple II hardware with constraints like 40,704 bytes of main RAM and uses a bytecode VM instead of native 6502 code.
- It features a REPL, file browser, text editor, and compiler, with support for digraph input on pre-IIe keyboards due to character limitations.
- Memory banking (e.g., Saturn 128K or IIe aux RAM) allows expanded features and larger programs, but requires separate disk images for different hardware.
- Development relied heavily on AI assistance (Claude and Codex) over 18 phases, with design documents to manage context and decisions.
