Xcode 26.3 – Leverage coding agents to tackle complex tasks autonomously

Summary: Xcode 26.3 introduces agentic coding, enabling developers to use AI agents like Anthropic’s Claude and OpenAI’s Codex to autonomously manage app development tasks. Agents can interact with project architecture, documentation, and tools, streamlining workflows and accelerating iteration.

What it does

Xcode 26.3 integrates AI coding agents that collaborate throughout the development lifecycle by exploring files, updating settings, and verifying work via Xcode Previews and builds. It also supports the Model Context Protocol, allowing use of any compatible agent.

Who it's for

Developers seeking to automate complex coding tasks and enhance productivity using AI agents within Xcode.

Why it matters

It enables autonomous task management and decision-making in app development, reducing manual effort and speeding up iteration cycles.
