NeowinApple has announced Xcode 26.3, which "unlocks the power of agentic coding" with AI agents like OpenAI's Codex. Read more...
The VergeApple is bringing agentic coding into Xcode with new integrations powered by Anthropic and OpenAI. Developers can use the built-in agents to help them write and edit code on their behalf, update project settings, and more.
Apple is previewing Xcode 26.3 with integrated support for coding agents such as Anthropic’s Claude Agent and OpenAI’s Codex . Announced February 3 , Xcode 26.3, the Apple-platforms-centered IDE, is available as a release candidate for members of the Apple Developer Program , with a release coming soon to the App Store . This latest version expands on intelligence features introduced in Xcode 26 in June 2025, which offered a coding assistant for writing and editing in the Swift language. In Xcode version 26.3, coding agents have access to more of Xcode’s capabilities. Agents like Codex and Claude Agent can work autonomously throughout the development lifecycle, supporting streamlined workflows and faster iteration. Agents can search documentation, explore file structures, update project settings, and verify their work visually by capturing Xcode previews and iterating through fixes and builds, according to Apple. Developers now can incorporate agents’ advanced reasoning directly into their development workflow. Combining the power of these agents with Xcode’s native capabilities provides the best results when developing for Apple platforms, according to Apple. Also new in Xcode 26.3 is support for Model Context Protocol (MCP) , an open standard that gives developers the flexibility to use any compatible agent or tool with Xcode.
