+# CLAUDE.md — iOS 客户端项目 AI 协作规范
+
+## 项目概览
+
+SwiftUI + MVVM 单向数据流 + SPM 多 target 模块化的 iOS「打卡/习惯追踪」客户端，架构对齐 Android NIA（`core/*` + `feature/*`）。
+
+## 目录结构
+
+- `ios-client.xcodeproj` / `ios-client/`：App 宿主（薄壳，只含 `@main` 挂载 `AppRootView`）
+- `IosClientKit/`：本地 SPM 包，承载所有模块
+  - `Sources/App`：组合根（`AppContainer` DI + `AppRootView` 导航）
+  - `Sources/CoreModel`：领域模型（`Sendable` 值类型，叶子）
+  - `Sources/CoreCommon`：通用工具（叶子）
+  - `Sources/CoreDomain`：Repository 协议 + UseCase（纯 Swift，不 import SwiftUI）
+  - `Sources/CoreRepository`：Repository 实现（Fake + 未来 OfflineFirst）
+  - `Sources/CoreNetwork`：DTO + APIClient（URLSession）
+  - `Sources/CoreDatabase`：SwiftData（`@Model` + `ModelContainer`）
+  - `Sources/DesignSystem`：设计 tokens
+  - `Sources/CoreUI`：可复用 SwiftUI 组件
+  - `Sources/FeatureHome` / `Sources/FeatureAuth`：Feature 模块
+
+## 依赖方向（硬约束，违反即编译不过）
+
+单向无环：`App → feature → core`；`App` 额外 → `CoreRepository`（装配具体实现）。
+
+- 领域模型只在 `CoreModel`，其余模块只能 import `CoreModel`。
+- Repository 协议只定义在 `CoreDomain`，实现在 `CoreRepository`。
+- `CoreDomain` 纯 Swift：禁止 `import SwiftUI` / 数据框架。
+- DTO 只在 `CoreNetwork`，领域 Model 只在 `CoreModel`，二者分离。
+- **禁止**命名任何模块为 `CoreData`（与苹果 `CoreData` 框架撞名，已统一为 `CoreRepository`）。
+
+## 状态管理约定
+
+- ViewModel：`@MainActor @Observable final class`，持有 `uiState`。
+- UiState：`enum` 关联值（对应 Kotlin `sealed interface`）。
+- Kotlin → Swift 映射：
+
+| Android (Kotlin) | iOS (Swift) |
+|---|---|
+| `Flow<T>` | `AsyncThrowingStream<T, Error>` |
+| `StateFlow` + `stateIn` | `@Observable` + `@MainActor` |
+| `flatMapLatest` | `Task` 取消自动 switch-to-latest |
+| `sealed interface UiState` | `enum UiState`（关联值）|
+| Hilt `@Inject` / AppContainer | 手写 `AppContainer` |
+| Retrofit + kotlinx.serialization | URLSession + Codable |
+| Room | SwiftData |
+| DataStore | `@AppStorage` / UserDefaults |
+
+## 代码风格
+
+- 跨模块符号一律 `public`，并加 `///` 文档注释。
+- 领域模型标记 `Sendable`。
+- 命名：类型 PascalCase，变量/函数 camelCase；UI 文案与注释可用中文。
+
+## 明确禁止
+
+- ❌ TCA、Swinject 等 DI 框架、Moya 等网络封装、任何第三方大框架
+- ❌ UIKit（除非 SwiftUI 确无法覆盖的极少数场景）
+- ❌ 循环依赖 / 反向 import
+
+## 构建 / 验证命令
+
+```bash
+# 编译包（同时做依赖环检测，SPM 遇环即报错）
+swift build --package-path IosClientKit
+
+# 模拟器编译 App
+xcodebuild -project ios-client.xcodeproj -scheme ios-client \
+  -destination 'generic/platform=iOS Simulator' \
+  CODE_SIGNING_ALLOWED=NO build
+
+# Lint
+swiftlint lint --strict
+```
+
+## 新增 Feature 清单
+
+1. 在 `IosClientKit/Package.swift` 的 `targets` 加 `FeatureXxx` 及依赖。
+2. 新建 `Sources/FeatureXxx/`：Screen + ViewModel + UiState（enum）。
+3. UseCase 放 `CoreDomain`，Repository 实现放 `CoreRepository`。
+4. 在 `App` 的 `AppContainer` 装配依赖、`AppRootView` 接入导航。

+# 贡献指南
+
+## 架构约束（提交前必须遵守）
+
+- 依赖单向：`App → feature → core`，禁止反向 import。
+- Repository 协议只在 `CoreDomain`，实现在 `CoreRepository`。
+- DTO 与领域 Model 分离（`CoreNetwork` / `CoreModel`）。
+- 禁止命名模块 `CoreData`（与苹果框架撞名，统一为 `CoreRepository`）。
+
+## 代码规范
+
+- 跨模块符号 `public` + `///` 文档注释。
+- 领域模型标记 `Sendable`。
+- ViewModel：`@MainActor @Observable`，UiState 用 `enum`。
+- 引入任何第三方依赖前，需在 PR 说明必要性（项目默认零第三方框架）。
+
+## 提交流程
+
+1. 从 `main` 新建分支：`feat/xxx`、`fix/xxx`。
+2. 本地跑通：
+   ```bash
+   swiftlint lint
+   xcodebuild -project ios-client.xcodeproj -scheme ios-client \
+     -destination 'generic/platform=iOS Simulator' \
+     CODE_SIGNING_ALLOWED=NO build
+   ```
+3. 发起 PR，至少一位 reviewer 通过后合并。
+
+## Commit 规范
+
+采用 Conventional Commits：`feat:` / `fix:` / `refactor:` / `docs:` / `chore:`。

+# ios-client
+
+SwiftUI + MVVM 单向数据流的 iOS「打卡/习惯追踪」客户端，采用 SPM 多 target 模块化，架构对齐 Android NIA（`core/*` + `feature/*`）。
+
+## 架构
+
+```
+App（组合根）──► feature/* ──► core/*
+                 │
+                 └──► CoreRepository ──► CoreNetwork / CoreDatabase / CoreDomain
+```
+
+依赖单向无环，由 SPM target 依赖天然强制（import 不到即编不过）。
+
+## 模块
+
+| 模块 | 职责 |
+|---|---|
+| CoreModel | 领域模型（叶子，`Sendable` 值类型）|
+| CoreCommon | 通用工具（日志等）|
+| CoreDomain | Repository 协议 + UseCase（纯 Swift）|
+| CoreRepository | Repository 实现（Fake / OfflineFirst）|
+| CoreNetwork | DTO + URLSession APIClient |
+| CoreDatabase | SwiftData（`@Model` + `ModelContainer`）|
+| DesignSystem | 设计 tokens（颜色/间距/圆角）|
+| CoreUI | 可复用 SwiftUI 组件 |
+| FeatureHome | 首页（打卡列表）|
+| FeatureAuth | 登录 / 我的（占位）|
+| App | 组合根（DI + 导航）|
+
+## 环境要求
+
+- Xcode 26.6+
+- iOS 17.0+（`@Observable` / SwiftData 下限）
+
+## 构建
+
+```bash
+xcodebuild -project ios-client.xcodeproj -scheme ios-client \
+  -destination 'generic/platform=iOS Simulator' \
+  CODE_SIGNING_ALLOWED=NO build
+```
+
+## Lint
+
+```bash
+brew install swiftlint   # 首次
+swiftlint lint
+```
