Xcode 27이 빌드를 깨뜨린다 — UIScene·Liquid Glass 강제, 이번 주 iOS 핵심 6

Installed the Xcode 27 Beta, only to find that a perfectly fine project won't even build? The fallout from WWDC 2026 has hit in earnest. With iOS 27, Xcode 27, and Swift 6.4 all arriving at once, we are facing a simultaneous clash of build failures, enforced lifecycles, mandatory design requirements, and stricter review processes. From UIScene migration and the mandatory implementation of Liquid Glass (removal of opt-out options) to stricter App Store low-quality app reviews, and even the positive news of Foundation Models becoming free—we have summarized the top 6 iOS trends of this week in just 7 minutes. Starting today, try building just one project with the Xcode 27 Beta. What breaks will be your to-do list for this quarter. 📌 Topics covered in this video: Xcode 27 Beta build breakage — iOS 15 minimum target, UIScene enforced, Intel Mac unsupported UIScene migration (TN3187) and deprecated APIs (Background Assets, MetricManager) Liquid Glass mandate — Automatic application upon Xcode 27 recompilation, opt-out removed App Store review rule revisions (June 9) — Rejection and removal of low-quality apps Foundation Models becoming free (for apps under 2 million downloads) and Swift 6.4, SwiftUI 🎯 Recommended for: Developers who need to complete migration before the official release of iOS 27 Teams needing to respond to the Liquid Glass mandate and check their build environments Those looking to quickly implement on-device AI with Foundation Models ⏱️ Timestamps: 00:00 Intro — The build won't work 00:38 This week at a glance: Six headlines 01:15 Why the build is breaking — Xcode 27 Beta 01:54 Priority 1 — UIScene Migration 02:35 Liquid Glass Mandatory 03:06 App Store Review Rules Revised 03:49 Positive News — Foundation Models Free 04:33 Swift 6.4 & SwiftUI — Pain Points Removed 05:25 Careers — Reshaping the Hiring Market 06:11 So What — Priorities for This Quarter 06:50 Wrap-up
