Apple brings agentic coding to Xcode 26.3 with Claude Agent and OpenAI's Codex integration
Apple has released Xcode 26.3, integrating Anthropic's Claude Agent and OpenAI's Codex directly into its development environment. Using Model Context Protocol, these AI-powered coding agents can autonomously build projects, run tests, and fix errors while accessing Apple's developer documentation. The update marks a shift from basic AI assistance to full agentic coding capabilities for iOS, Mac, and other Apple platform developers.
