The iPhone 17, iPhone Air, and iPhone 17 Pro feature a square-sensor ultra-wide front camera with a 95Ā° field of view. iOS 26 exposes new APIs ā dynamic aspect ratio and a smart framing monitor ā so apps can deliver auto-zoom, auto-rotate, and Center Stage tracking for selfies, recordings, and video calls.
ā¢ Dynamic aspect ratio lets you switch between portrait, landscape, and square crops seamlessly without rebuilding the capture session ā enabling one-tap Tap-to-Rotate UX.
ā¢ The AVCaptureSmartFramingMonitor delivers real-time framing recommendations (aspect ratio + zoom factor) based on face/gaze detection, so group selfies are always well-framed automatically.
ā¢ A new low-latency stabilization mode and built-in sensor orientation compensation mean video calls and recordings just work correctly on the new sensor without extra rotation math.
iOS 27 adds sectioned queries, codable model attributes, ResultsObserver for non-SwiftUI change observation, and HistoryObserver for reacting to persistent history changes in SwiftData.
iOS 27 expands the App Intents framework with RelevantEntities for contextual content surfacing, EntityCollection for high-performance batch parameter handling, SyncableEntity for cross-device Siri continuity, native Duration/PersonNameComponents parameter types, and @UnionValue for multi-type parameters ā plus extended intent execution time limits.
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 ā including where and how strings are used ā to produce accurate, consistent translations across all languages.
