Copyright Walls Demolished by Vibe Coding, and the Developer's New Moat -- Fatbobman's Swift Weekly #131

AI-powered vibe coding is eroding traditional software copyright protections from multiple angles: the bar for establishing code ownership has risen, proving infringement is harder, and functional cloning has become trivially easy. A Reddit incident exposed a developer who used AI to repackage Paul Hudson's open-source Ignite framework with minimal changes, while a macOS app was pixel-for-pixel cloned shortly after launch. China's copyright authority now requires notarized declarations that no AI was used in code development, and European/US case law is trending similarly. The newsletter argues that developers' true moat going forward is community trust and maker credibility, not code secrecy. Also covered: the Swift Blog Carnival on 'Tiny Languages', SwiftUI menu selection patterns, List alternatives using Container View API, exposing AppIntents as MCP tools, interactive WidgetKit widgets, and iOS/macOS file storage with iCloud.
