「Xcode 26.0」が公開

Xcode 26 includes Swift 6.2 and SDKs for iOS 26, iPadOS 26, tvOS 26, watchOS 26, visionOS 26, and macOS 26.

Enhance your development workflow with coding intelligence features that help you write code, generate tests and documentation, fix errors, refactor existing implementations, and navigate codebases. Xcode has integrated support for ChatGPT and Claude user accounts. You can also use your API key for any model provider that supports the Chat Completions API, or download and run a local model on Macs with Apple silicon.

• Interact with code using natural language in the coding assistant, with automatic context gathering, conversation history, and file attachment support.

• Coding Tools provide contextual actions to quickly generate documentation, explain highlighted code, generate previews and playgrounds, and make inline changes.

• Predictive code completion is faster and uses more context from your code, all running locally.

Also in Xcode 26:

• The #Playground macro enables interactive debugging and code exploration in the preview panel.

• Icon Composer streamlines icon creation from a single design with adjustable depth properties and dynamic lighting effects, and offers customization across Default, Dark, and Mono rendering modes.

• A redesigned tab experience simplifies navigation with features like in-tab navigation and pinning to keep files in focus.

• Compilation Caching accelerates build times with performance improvements when switching between branches or performing clean builds.

• New instruments enhance app analysis with Processor Trace capturing every function call, SwiftUI for view profiling, Power Profiler for battery and thermal analysis, and CPU Counters for identifying performance bottlenecks.

• Swift concurrency debugging follows execution across asynchronous functions and threads with readable concurrency type representations and enhanced visibility for task properties and relationships.

• String Catalogs simplify localization with type-safe Swift symbols for direct string access, autocomplete support, and AI-generated contextual comments using on-device intelligence.

• Voice Control now supports code dictation in Swift with syntax-aware recognition and automatic formatting.
