What it is ​

Swift Pieces is a library of animated SwiftUI components for native iOS apps. The public site groups pieces into buttons, inputs, cards, navigation, feedback, charts and AI interfaces, with code-oriented install paths and Pro screens and app templates.

When to open it ​

  • When building a native iOS app and looking for concrete interaction, haptic and motion patterns.
  • When an agent needs a SwiftUI example for loading states, AI chat, voice mode, glass effects or gesture-heavy controls.

Most useful ​

  • Component categories: browse controls, cards, navigation, feedback, AI and animations.
  • Motion and haptics: components pair spring motion, drag and hold states with haptic feedback; the site's guides explain patterns for animations and haptics.
  • Pro screens: the public screen library previews wallet, dashboard, chat, voice and paywall patterns; app templates provide complete Xcode projects.
  • Installation: free pieces can be copied, added by CLI or retrieved through an agent; source is written into the consumer project rather than linked as a runtime package.

Using it with agents ​

The site provides llms.txt, an MCP guide, a CLI and a registry at https://swiftpieces.com/r/index.json. Free library install instructions are in the MCP docs; the Pro side has its own agent docs.

Watch out for ​

  • This is native SwiftUI for iOS, not a web or React component library.
  • Free components use MIT plus Commons Clause: they may be used in apps, but the pieces themselves cannot be sold, sublicensed or redistributed as a library.
  • Pro is licensed per developer. Each developer who installs or works with Pro pieces needs a separate license; the listed price is $199 one-time at review.
  • Check that interactive components respect Reduce Motion and provide a non-haptic path where needed.

Reusable ideas ​

  • Make interaction states explicit: pressed, held, loading, success and failure can each have distinct motion and feedback.
  • Tune haptics to meaningful transitions rather than triggering them on every frame.
  • Preview code against real device-size constraints, especially for thumb-reachable controls and gesture-driven cards.
