Swift 6.1 ships strict concurrency on by default, with region-based isolation catching data races at compile time. SwiftData, introduced with iOS 17, has nearly displaced Core Data thanks to iOS 18 additions like the History API and composite keys. The Foundation Models framework gives every app access to a ~3B parameter on-device LLM with tool calling and Guided Generation as the heart of Apple Intelligence. On the server side, Vapor 4, Hummingbird 2, and AWS Lambda Swift are growing; on cross-platform, Skip (Swift→Android) and Swift Wasm 6 are real options. Embedded Swift runs on the Raspberry Pi Pico and ARM Cortex-M without malloc. This article maps the entire 2026 Apple developer landscape — from Swift 6 concurrency through SwiftUI 5 animations, App Intents, Swift Testing, Swift Macros, SwiftPM 6, and TCA 1.x.

Swift 6.1은 strict concurrency를 기본으로 켜고, region-based isolation으로 데이터 레이스를 컴파일타임에 잡는다. SwiftData는 iOS 17에서 등장한 뒤 iOS 18의 History API와 composite key 지원으로 Core Data의 자리를 거의 차지했다. Foundation Models 프레임워크는 약 30억 파라미터의 온디바이스 LLM에 tool calling과 Guided Generation을 얹어 Apple Intelligence의 핵심이 됐다. 한편 서버에서는 Vapor 4·Hummingbird 2·AWS Lambda Swift가, 멀티플랫폼에서는 Skip(Swift→Android)과 Swift Wasm 6가 자라고 있다. Embedded Swift는 Raspberry Pi Pico와 ARM Cortex-M에서 malloc 없이 동작한다. 이 글은 Swift 6 동시성부터 SwiftUI 5 애니메이션·App Intents·Swift Testing·Swift Macros·SwiftPM 6·TCA 1.x까지, 2026년 Apple 개발자가 알아야 할 모든 것을 한 번에 정리한다.
