SwiftUI 5 introduces Adaptive Layout Engine and AI-assisted code suggestions in Xcode

At this year’s developer refresh, Apple unveiled SwiftUI 5 with two headline features: an Adaptive Layout Engine that automatically reconciles layout constraints across devices, and integrated AI-assisted code suggestions inside Xcode for UI construction. The engine aims to make one codebase produce polished interfaces across iPhone, iPad, Mac and Vision devices.

Xcode’s new completion widget uses an on-device model to suggest SwiftUI layouts, propose accessibility attributes, and infer bindings from view hierarchies. Apple emphasized privacy: the assistant runs locally for most tasks, with optional opt-in cloud acceleration for large projects.

Designers and engineers will find improved layout debugging tools in Instruments, including a visual constraint inspector tuned for SwiftUI’s declarative style. Apple has also added migration tools to help projects adapt existing UIKit views into the new adaptive paradigm with fewer manual tweaks.
