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
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.

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.
