swiftui

A set of SwiftUI rules for building Apple-app interfaces with Swift, covering views, local and shared state, reusable styling, dependency sharing, and large lists.

In plain words
What is it for?
Use it when designing SwiftUI views, choosing between state-management patterns, passing editable values to child views, injecting shared dependencies, styling reusable components, or displaying large collections.
Why use it?
It helps keep SwiftUI views small and focused while making state flow easier to manage across iPhone, Mac, Apple Watch, and Apple TV apps.

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.

Made for: Cursor.

Per session 0 Nothing until a file matches its globs; then the whole rule loads.
When invoked 185 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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.

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 规则

  • 使用结构体(struct)创建视图,并保持其小巧和专注
  • 使用 @State 管理简单的视图本地状态
  • 使用带有 @Published 的 @ObservableObject 管理共享状态
  • 使用 @Binding 将可变状态传递给子视图
  • 创建自定义 ViewModifiers 实现可复用的样式
  • 使用环境对象(environment objects)进行依赖注入
  • 对大型集合使用 LazyVStack 和 LazyHStack
  • 将复杂的视图逻辑提取到单独的组件中

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.

swiftui is a cursor rule published in the GitHub repository WangTingYeYe/llm-agent-study (4 stars, last pushed 1y ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 185 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
