Claude should have gone for native apps and demonstrated that it is possible to do anything with their AI.
I'm currently building a macOS AI chat app. Generally SwiftUI/AppKit is far better than Web but it performs bad in few areas. One of them is Markdown viewer. Swift Markdown libraries are slow and lacks some features like Mermaid diagrams. To work around this, some of my competitors use Tauri/Electron and few others use WKWebView inside Swift app.
Initially I tried WKWebView. Performance was fine and the bridge between JS and Swift was not that hard to implement but I started seeing few problems especially due to the fact that WebView runs as separate process and usually a single WebView instance is reused across views.
After few attempts to fix them, I gave up the idea and tempted to go fully with Web rendering with Tauri but as a mac developer I couldn't think about building this app in React. So I started building my own Markdown library. After a month of work, I now have a high-performance Markdown library built with Rust and TextKit. It supports streaming and Markdown extensions like Mermaid.
Most of the code was written by Claude Opus, and some tricky parts were solved by Codex. The important lesson I learned is that I’m no longer going to accept limitations in tech and stop there. If something isn’t available in Swift but is available in JS, I’m going to port it. It’s surprisingly doable with Claude.
I'm working on a decade old problem - searching files in macOS. Started building to solve my own issues after realising none of the tools supports what I need. Very excited about the upcoming feature that I'm releasing this week as it lets you search inside specific folders - something that is not offered by other tools
As many of you, I'm too frustrated with Finder in macOS to a point that I learnt SwiftUI to build my own Finder companion. Yet every day I discover new hidden gems. I have started documenting them and have plans to do that in future. Sharing it here, hope you find it useful
