Xcode 26.3 introduces support for agentic coding, a new way in Xcode for developers to build apps using coding agents such as Anthropic’s Claude Agent and OpenAI’s Codex. With agentic coding, Xcode can work with greater autonomy toward a developer’s goals — from breaking down tasks to making decisions based on the project architecture and using built-in tools.
Couldn't get enough AI agents in your coding environments?
With Xcode 26.3, coding agents get access "to even more of Xcode’s capabilities. Agents like @Claude by Anthropic Agent and @Codex by OpenAI can now collaborate throughout the entire development life cycle, giving developers the power to streamline workflows, iterate faster, and bring ideas to life like never before. Agents can search documentation, explore file structures, update project settings, and verify their work visually by capturing Xcode Previews and iterating through builds and fixes."

In addition to these built-in integrations, Xcode 26.3 makes its capabilities available through the Model Context Protocol, an open standard that gives developers the flexibility to use any compatible agent or tool with Xcode.
Definitely excited to get rolling with the MCP hooks. Skills over xcodebuild work well as well and reduce context bloat. Would be good to see if the Xcode team can expose some finder grained tools through xcodebuild that we can surface through skills
I really hope someone make Xcode running on Windows. I have left a goal to be Swift Developer cause of it. Is there any Developer having similar problem to solve, i am developer myself, welcome with your ideas.
Interested to see how this works in practice. As an iOS developers this has been needed for a while now!
How granular is the permission model in Xcode 26.3 when Codex or Claude Agent can edit files and project settings, can I scope it to a target or folder and require a clean build and tests before it checkpoints? Without that, agentic coding won"t feel safe on real apps.
