+# KiwiSwift, 한국어 형태소 분석기 Kiwi의 iOS 바인딩
+
+> **🚧 현재 상태**: iOS 바인딩의 기본 구조가 구현되었으며, 프로토타입 단계입니다. 
+> 실제 사용을 위해서는 추가 개발과 테스트가 필요합니다.
+
+## 현재 구현 상태
+
+✅ **완료된 작업**:
+- 기본 CMake 빌드 설정
+- C++ 브릿지 구현 (`csrc/kiwi_swift.cpp`)
+- Objective-C 헤더 (`include/Kiwi.h`)
+- Swift API 래퍼 (`swift/Kiwi.swift`)
+- Swift Package Manager 설정 (`Package.swift`)
+- CocoaPods 스펙 (`KiwiSwift.podspec`)
+- 기본 단위 테스트 구조
+
+🚧 **추가 개발 필요**:
+- iOS SDK와의 완전한 통합 테스트
+- 모델 파일 배포 방식 최적화
+- 메모리 사용량 최적화
+- 에러 핸들링 개선
+- 문서화 완성
+
+## 현재 API 구조
+
+기본적인 Swift API가 구현되어 있습니다:
+
+```swift
+import KiwiSwift
+
+// Kiwi 인스턴스 생성
+let kiwi = try Kiwi(modelPath: "path/to/model")
+
+// 형태소 분석
+let tokens = try kiwi.tokenize("안녕하세요!", options: .normalizeAll)
+for token in tokens {
+    print("\(token.form) / \(token.tag)")
+}
+
+// 문장 분리
+let sentences = try kiwi.splitSentences("첫 번째 문장입니다. 두 번째 문장입니다.")
+
+// 비동기 처리
+kiwi.tokenize("비동기 처리 예제", options: .normalizeAll) { result in
+    switch result {
+    case .success(let tokens):
+        print("Tokens: \(tokens)")
+    case .failure(let error):
+        print("Error: \(error)")
+    }
+}
+```
+
+## 빌드 방법
+
+### 요구사항
+- Xcode 12.0+ 
+- iOS 12.0+ SDK
+- CMake 3.12+
+- ios-cmake 툴체인 (권장)
+
+### 빌드 단계
+
+1. **iOS 툴체인 설정**:
+```bash
+git clone https://github.com/leetal/ios-cmake.git
+```
+
+2. **iOS용 빌드**:
+```bash
+cd bindings/ios
+mkdir build && cd build
+
+# iOS 기기용
+cmake .. \
+  -DCMAKE_TOOLCHAIN_FILE=path/to/ios-cmake/ios.toolchain.cmake \
+  -DPLATFORM=OS64 \
+  -DKIWI_IOS_BINDING=ON \
+  -DKIWI_BUILD_TEST=OFF \
+  -DKIWI_BUILD_CLI=OFF
+
+make
+
+# iOS 시뮬레이터용
+cmake .. \
+  -DCMAKE_TOOLCHAIN_FILE=path/to/ios-cmake/ios.toolchain.cmake \
+  -DPLATFORM=SIMULATOR64 \
+  -DKIWI_IOS_BINDING=ON
+
+make
+```
+
+### Swift Package Manager 사용
+
+1. Xcode에서 프로젝트 열기
+2. File → Add Package Dependencies...
+3. Repository URL: `https://github.com/bab2min/Kiwi.git`
+4. Package 폴더: `bindings/ios`
+
+### CocoaPods 사용
+
+`Podfile`에 추가:
+```ruby
+pod 'KiwiSwift', :git => 'https://github.com/bab2min/Kiwi.git', :subfolder => 'bindings/ios'
+```
+
+### 목표
+- **Swift/Objective-C 지원**: 네이티브 iOS 개발 언어 완전 지원
+- **CocoaPods/SPM 배포**: 표준 iOS 패키지 매니저를 통한 쉬운 설치
+- **iOS 성능 최적화**: 모바일 환경에 최적화된 메모리 사용량과 배터리 효율성
+- **동일한 API**: 다른 플랫폼과 일관된 API 제공
+
+### 기술적 요구사항
+- **최소 iOS 버전**: iOS 12.0+
+- **아키텍처**: ARM64 (iPhone 5s 이후 모든 기기)
+- **언어**: Swift 5.0+, Objective-C 호환성
+- **프레임워크**: C++ 코어와 Swift/Objective-C 간의 브릿지 구현
+
+### 예상 API 구조
+
+```swift
+import KiwiSwift
+
+// Kiwi 인스턴스 생성
+let kiwi = try Kiwi(modelPath: "path/to/model")
+
+// 형태소 분석
+let tokens = try kiwi.tokenize("안녕하세요!", options: [.normalizeAll])
+for token in tokens {
+    print("\(token.form) / \(token.tag)")
+}
+
+// 문장 분리
+let sentences = try kiwi.splitSentences("첫 번째 문장입니다. 두 번째 문장입니다.")
+```
+
+### 패키지 배포 계획
+
+#### CocoaPods
+```ruby
+pod 'KiwiSwift', '~> 0.21.0'
+```
+
+#### Swift Package Manager
+```swift
+dependencies: [
+    .package(url: "https://github.com/bab2min/Kiwi.git", from: "0.21.0")
+]
+```
+
+### 개발 일정
+
+개발 일정은 현재 미정이며, 다음 요소들에 따라 결정될 예정입니다:
+
+1. **커뮤니티 수요**: iOS 개발자들의 관심도와 요청
+2. **개발자 참여**: iOS 네이티브 개발 경험이 있는 기여자 참여
+3. **기술적 과제**: C++ 코어와 Swift 간 효율적인 브릿지 구현
+
+### 기여 방법
+
+iOS 바인딩 개발에 관심이 있으시다면:
+
+1. **Issue 참여**: [GitHub Issues](https://github.com/bab2min/Kiwi/issues)에서 iOS 관련 논의에 참여
+2. **기술 검토**: C++/Objective-C++/Swift 브릿지 구현 방안 제안
+3. **프로토타입 개발**: 초기 iOS 바인딩 프로토타입 구현
+4. **문서화**: iOS 개발자를 위한 가이드 작성
+
+### 기술적 고려사항
+
+#### 메모리 관리
+- iOS의 ARC(Automatic Reference Counting)와 C++ 객체 생명주기 관리
+- 대용량 모델 파일의 효율적인 메모리 사용
+
+#### 성능 최적화
+- 모바일 CPU에 최적화된 컴파일 옵션
+- 배터리 효율성을 고려한 연산 최적화
+
+#### 앱 스토어 정책
+- App Store 배포 시 정적 라이브러리 요구사항 준수
+- bitcode 지원 고려
+
+## 연락처

+iOS 바인딩 개발에 대한 문의나 기여 의사가 있으시면:
+
+- GitHub Issues에 iOS 라벨로 이슈 생성
+- 메인테이너(@bab2min)에게 직접 연락
