The author describes using large language models like Claude Opus 4.6 and GPT-5.4 to 'vibe code' SwiftUI macOS apps without opening Xcode, creating simple monitoring tools like Bandwidther and Gpuer. This approach leverages the ability to fit full SwiftUI apps in single text files and generate functional code from minimal prompts. The article highlights the fun and efficiency of this experimental workflow for building basic utility applications.
