mobile

mobile is a skill for Claude Code from qinye6/pi-ccg. It costs 44 tokens per session (2,520 once invoked), scanned A, a copy of mobile, MIT.

A mobile-development skill covering iOS, Android, and cross-platform apps such as React Native and Flutter. It includes common patterns for screens, state, networking, storage, and testing.

In plain words
What is it for?
Use it to build or change SwiftUI or UIKit apps, Android apps with Jetpack Compose, or cross-platform apps with React Native or Flutter.
Why use it?
It gives an agent relevant guidance when mobile code involves different languages, frameworks, and platform conventions.

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

mobile 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 6d 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.

Origin

This is a copy

100% identical to mobile — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

iOS 开发

SwiftUI 核心模式

  • View 组件:struct MyView: View { var body: some View { ... } }
  • State 管理:
    • @State — 本地状态
    • @Binding — 父子双向绑定
    • @StateObject — 拥有 ObservableObject
    • @ObservedObject — 引用 ObservableObject
    • @EnvironmentObject / @Environment — 全局注入
  • ObservableObject:@Published 属性自动触发 UI 更新
  • Custom ViewModifier:struct CardModifier: ViewModifier + extension View { func cardStyle() }
  • 生命周期:.task { await ... } / .onAppear / .onDisappear

UIKit 集成

  • UIViewControllerRepresentable:包装 UIViewController 到 SwiftUI
  • UIViewRepresentable:包装 UIView 到 SwiftUI
  • Coordinator 模式:处理 delegate 回调
  • Auto Layout:NSLayoutConstraint.activate([...]) + translatesAutoresizingMaskIntoConstraints = false

Combine 响应式

  • Publisher:URLSession.shared.dataTaskPublishermapdecodeeraseToAnyPublisher
  • 订阅:.sink(receiveCompletion:receiveValue:) + .store(in: &cancellables)
  • 常用 Operators:debounce / removeDuplicates / combineLatest / flatMap
  • Subject:PassthroughSubject(无初始值)/ CurrentValueSubject(有初始值)

iOS 架构

MVVM(推荐):

  • Model:Codable 数据结构
  • Repository:protocol + async throws 方法
  • ViewModel:@MainActor class VM: ObservableObject + @Published 属性
  • View:@StateObject private var viewModel = VM()

VIPER(复杂场景):

  • View ←→ Presenter ←→ Interactor → Entity
  • Router 处理导航

网络层

  • APIClient:泛型 func get<T: Decodable>(_ path:) async throws -> T
  • Token 管理:request.setValue("Bearer \(token)", forHTTPHeaderField: "Authorization")
  • 错误处理:enum APIError: Error { case invalidURL, invalidResponse, httpError(Int) }

数据持久化

  • UserDefaults:@propertyWrapper struct UserDefault<T> 简化访问
  • Keychain:SecItemAdd / SecItemCopyMatching 存储敏感数据
  • Core Data:NSPersistentContainer + NSManagedObjectContext
  • SwiftData(iOS 17+):@Model 宏简化持久化

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.
