swiftui is a skill for Claude Code from rshankras/claude-code-apple-skills. It costs 70 tokens per session (626 once invoked), scanned A, original, MIT.

A collection of guides for building SwiftUI apps, Apple's system for describing app screens in Swift code. It covers state and rendering, custom layouts, alarms, charts, rich text, toolbars, and embedded web content.

In plain words
What is it for?
Use it when building or debugging SwiftUI interfaces, including layouts, scrolling, state, toolbars, styled text, alarms, charts, and web views.
Why use it?
It gives one place to choose focused guidance for common SwiftUI tasks instead of searching across unrelated examples. The included topics cover both everyday interface work and newer platform APIs.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

ModelPer sessionOnce invoked
Fable 5.1 $0.00070 $0.00626
Opus 5.5 $0.00028 $0.00250
Sonnet 5.5 $0.00014 $0.00125

Security

Grade A, and why

swiftui scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

SwiftUI Skills

Focused SwiftUI framework skills — each sub-skill covers one API area in depth.

When This Skill Activates

Use this skill when the user:

  • Has state/rendering bugs: state resets, over-rendering, flashing lists, animation crossfades (data-flow)
  • Is choosing @State vs @Bindable vs @Environment or migrating to Observation (data-flow)
  • Builds custom layouts or containers, or fights lazy-stack/scroll performance (layout)
  • Wants alarms or timers with AlarmKit (custom UI, Live Activities, snooze)
  • Is creating 3D data visualizations with Swift Charts (Chart3D, SurfacePlot)
  • Needs styled text or rich text editing (Text, AttributedString, TextEditor)
  • Is implementing or customizing toolbars (customizable toolbars, search integration)
  • Wants to embed web content (WebView, WebPage, JavaScript interop)

Available Skills

How to Route

  1. Match the request to a row above.
  2. Read that SKILL.md (relative to this file) plus any reference files it lists.
  3. Apply the guidance to the user's code.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
