Apple 및 Swift 커뮤니티는 Swift 6 출시 이후에도 언어 확장, 성능 개선, 플랫폼 지원 강화 등을 목표로 다양한 개발 로드맵을 공개하고 있습니다. 주요 향후 버전별 계획은 다음과 같습니다.
1. Swift 6.1 (2025년 6월 공개)
- 비동기/동시성 개선:
nonisolated키워드를 타입 및 확장(extension)에 적용해@MainActor추론을 제어 가능[1]. - 태스크 그룹 추론:
withTaskGroup과withThrowingTaskGroup의 결과 타입 추론 지원으로 가독성 및 작성 편의성 향상[1]. - Objective-C 구현 통합:
@objc @implementation속성을 이용해 Objective-C 선언부를 Swift로 구현 가능[1]. - 트레일링 콤마 확장: 튜플, 매개변수 리스트, 제네릭 등 다양한 문법 요소에서 트레일링 콤마 지원[1].
- 패키지 트레잇(Package Traits): 임베디드, WebAssembly 등 환경별 기능 제공 조건 정의 및 의존성 구성[1].
- 백그라운드 인덱싱: SourceKit-LSP 기반 SwiftPM 프로젝트에서 빌드 없이 실시간 코드 편집 지원[1].
- 테스트 스코핑 트레잇: 커스텀 TestTrait으로 테스트 전후 로직 공유 가능[1].
- DocC 링크 개선: 매개변수 및 반환 타입 조합으로 오버로드 심볼 링크 명시성 향상[1].
2. Swift 6.2 (2025년 중)
- 고성능 기능: Inline Arrays(고정 크기 배열), Span 타입(안전 버퍼 포인터 대체) 추가[2].
- 동시성 추가 속성: 새로운
@concurrent어트리뷰트 제공으로 비동기 코드 안전성 강화[2]. - C++ 상호 운용성 개선: C++ 인터롭 지원 확장 및 swift-java 프로젝트 연계를 통한 Java 상호 운용성 강화[2].
- 컨테이너화(Containerization): Apple 실리콘 최적화된 Linux 컨테이너 생성/실행 도구 공개[2].
3. Swift 6.3 이상 및 Swift 7
3.1 Swift 6.x 시리즈 공통 목표
- 데이터 레이스 안전성: Swift 6 언어 모드 기반 런타임 데이터 레이스 검사 기능 개선[3][4].
- 저수준 성능 최적화: ARC 예측성 개선, move-only 및 borrow 타입 등 메모리 제어 기능 향상[5][6].
- 플랫폼 확장: 임베디드 Swift, Windows, Linux 지원 강화 및 새로운 플랫폼 제안[3][5].
- 도구체인 통합: Swift Build 오픈소스화 및 SwiftPM과 Xcode 빌드 엔진 통합 작업[7].
3.2 Swift 7 예비 로드맵
- 변형 제네릭(Variadic Generics) 및 DSL(함수 빌더) 완성[8][3].
- C++ 및 Java 상호 운용: 더 간결하고 안전한 외부 언어 연동 지원 확대[5][2].
- Embedded Swift: 메모리·연산 자원이 제한된 마이크로컨트롤러 지원용 언어 부분집합 강화[8][3].
- 소규모·점진적 동시성 도입: 초급 사용자를 위한 점진적 동시성 도입 경로(3단계 접근성 개선)[4].
3.3 커뮤니티 참여
Swift Evolution 저장소에서 제안서(SE-xxxx)를 통해 향후 기능 토론 및 피드백 가능하며, 기여자는 공개 포럼에서 제안서를 검토하고 논의할 수 있습니다[9].
위 로드맵은 Apple 공식 블로그, Swift.org 게시물 및 Swift Evolution 포럼을 종합한 것이며, 각 버전별 상세 릴리스 노트는 해당 버전 공개 시 Swift.org에서 확인할 수 있습니다.
