A reference guide to SwiftUI, Apple’s framework for building app interfaces with Swift code. It covers views, layouts, navigation, state, data binding, drawing, and newer iOS features.

Use it when building screens, lists, tabs, navigation, custom drawing, or views that manage state with tools such as @State, @Binding, and @Observable.

It helps you locate the correct SwiftUI APIs for interface structure and for sharing or updating data between views.

swiftui — Skill for Claude Code by Prisma-Labs-Dev

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add Prisma-Labs-Dev/apple-skills --skill swiftui

Clone the repo

git clone --depth 1 https://github.com/Prisma-Labs-Dev/apple-skills

Made for: Claude Code.

Or install apple-skills, the plugin that ships this one along with the rest of its 36 skills.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00037	$0.00863
Opus 5	$0.00018	$0.00432
Sonnet 5	$0.00007	$0.00173
Haiku 4.5	$0.00004	$0.00086

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 7d 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.

Fetching More Docs

Search this skill's local .md files first.
If the topic is not here, check the other installed Apple skills you have available by their names, descriptions, or SKILL.md frontmatter, then grep their local files. This is faster and uses less context than fetching new docs from the internet.
If no installed skill has the page, use the relevant documentation path from swiftui-overview.md with the sosumi.ai Markdown mirror. For example, /documentation/swiftui/button maps to https://sosumi.ai/documentation/swiftui/button.

Changes

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.
