Swift 6.0 (September 2024) flipped strict concurrency on by default and started catching data races at compile time. Swift 6.1 (2025) stabilized the complete mode and raw identifiers. Swift 6.2 preview, in beta during H1 2026, promises an even smoother concurrency experience. SwiftUI 6 (iOS 18) shipped mesh gradients, scroll position bindings, and view transitions. SwiftData has cemented itself as the Core Data successor. On the server, Vapor 4 remains the de facto standard while Hummingbird 2 climbs as the Swift Server Workgroup-backed alternative. The tooling layer — Tuist, Mint, swift-package-manager for builds, swift-syntax/swift-format/SwiftLint/SwiftFormat for code quality, and swift-testing (new in Swift 6.0) replacing XCTest — has consolidated. And in November 2024 the Android Swift Working Group launched, putting Swift on Android on a real track. swift-foundation rewrite, Embedded Swift, Macros, Observation — we map the entire Swift ecosystem as of May 2026.

Swift 6.0이 2024년 9월 strict concurrency를 default로 켜며 데이터 레이스를 컴파일 타임에 잡기 시작했고, Swift 6.1이 2025년에 raw identifiers와 complete 모드를 안정화했고, Swift 6.2 preview가 2026년 상반기에 더 매끈한 concurrency를 약속하고 있다. SwiftUI 6(iOS 18)는 Mesh gradient, scroll position binding, view transition을 들고 왔고, SwiftData가 Core Data 후속으로 자리를 잡았다. 서버에서는 Vapor 4가 표준 자리를 지키는 가운데 Hummingbird 2가 Swift Server Workgroup 후원으로 올라왔다. 도구 쪽에서는 Tuist·Mint·swift-package-manager가 빌드와 도구 설치를 책임지고, swift-syntax·swift-format·SwiftLint·SwiftFormat이 코드 품질을, swift-testing(Swift 6.0 신규 프레임워크)이 XCTest를 대체한다. 그리고 2024년 11월 Android Swift Working Group이 발족하며 Swift on Android가 현실 트랙에 들어왔다. swift-foundation 재작성, Embedded Swift 키노트, Macros, Observation까지 — 2026년 5월 Swift 생태계를 한 번에 그린다.
