iOS 27 introduces the Poster Generic pass style for bold, image-forward loyalty and membership cards, four new barcode formats (EAN-13, Code 39, Codabar, ITF), and a new featuredActions API that surfaces contextual actions below any pass style. A new Pass Designer Mac app and Pass Builder Swift package streamline template creation and server-side pass signing.
• Poster Generic enables visually rich membership and loyalty passes with full-bleed artwork, giving brands a premium canvas without custom UI
• Featured actions let any pass style (not just event tickets) expose deep-link actions like viewing member benefits or managing bookings directly from Wallet
• Pass Builder (Swift on Server, Mac + Linux) automates manifest generation, signing, and packaging, replacing manual shell-script pipelines for pass distribution at scale
iOS 27 adds sectioned queries, codable model attributes, ResultsObserver for non-SwiftUI change observation, and HistoryObserver for reacting to persistent history changes in SwiftData.

USDKit is a new first-party Swift framework introduced in iOS/macOS 27 that brings native USD scene creation, composition, modification, and export capabilities to Apple platform apps, with deep RealityKit and Spatial Preview integration.
Xcode 27 introduces an agentic localization workflow that lets you ask a coding agent to translate your entire app directly inside Xcode, leveraging String Catalog context — including where and how strings are used — to produce accurate, consistent translations across all languages.
