Simon Willison: 'Vibe Coding SwiftUI Apps Is a Lot of Fun' — Claude Opus 4.6 Builds Native Mac Apps Without Knowing Swift
Willison published a March 27 post documenting how he vibe-coded native macOS menu bar apps (Bandwidther and Gpuer) using Claude Opus 4.6 and GPT-5.4 — without knowing Swift and barely glancing at the generated code. He describes it as 'classic vibe coding' where he was 'completely unqualified to evaluate if the numbers and charts were credible or accurate.' Both models proved competent at SwiftUI without needing Xcode, and source code is on GitHub as examples of what Claude can do with native platform frameworks.
