Solo dev, working on a native macOS app in SwiftUI. AI has been most useful for the boilerplate - repetitive view layouts, FileManager calls, figuring out AppKit bridging weirdness. It basically replaced Stack Overflow for me.

Where it breaks down is state management. The suggestions look right but introduce subtle bugs in how data flows between views. I've learned to only use it for isolated, well-scoped tasks. Anything that touches multiple components, I write myself.
