Axint is the Apple-native execution layer for AI agents. It gives Claude 13 MCP tools for generating validated Swift — App Intents for Siri, SwiftUI views, WidgetKit widgets, and full app scaffolds. Instead of generating Swift that looks right but fails Apple's framework rules, Claude now produces build-ready code that passes 150 Apple-specific diagnostic checks. One defineIntent() call replaces ~80 lines of Swift. One defineWidget() replaces ~150. Claude scaffolds, compiles, validates, auto-fixes, and hands you Xcode-ready output.
