SwiftData in iOS 27: Observation and History
iOS 27 gives SwiftData first-class change observation with ResultsObserver, persistent-history observation with HistoryObserver, and codable attribute storage.
AI & TechnologySwiftUI Performance and Interop in iOS 27
How iOS 27 SwiftUI handles lazy-stack scrolling, GPU shader effects, and AppKit/UIKit interop, drawn from three official WWDC26 UI Frameworks sessions.
AI & TechnologyRealityKit And Reality Composer Pro 3 In 2026
WWDC26 matured Apple's spatial pipeline: RealityKit lighting and cloth, plus a standalone Reality Composer Pro 3 with live preview and Xcode plug-ins.
AI & TechnologyFoundation Models in iOS 27: Tool-Calling Control
iOS 27 adds GenerationOptions.ToolCallingMode to steer how the on-device model uses tools, plus built-in Vision tools: OCRTool and BarcodeReaderTool.
AI & TechnologyMetal for Machine Learning in 2026
WWDC26 made Metal a first-class ML compute surface: Metal tensors for custom kernels, the M5 neural accelerator, real-time neural rendering, and MLX Swift.
AI & TechnologyApp Intents in iOS 27: Background, Sync, Spotlight
iOS 27 gives App Intents background execution past 30 seconds via LongRunningIntent, cross-device identity with SyncableEntity, and Spotlight reindexing.
AI & TechnologyBuilding a Responsive Camera App in iOS 27
iOS 27 cuts camera launch in half with Deferred Start, adds Pro Video Storage for ProRes writes, and brings the Center Stage square front camera to your app.
AI & TechnologyYour Agent Has Two Untrusted Inputs
AI agents have two untrusted inputs: code the model writes and tool output it reads. One now has a real WASM sandbox; the other, MCP tool poisoning, does not.
