Starting with Xcode 27, developers will be able to natively use Google Gemini, in addition to Claude Code and OpenAI Codex, to plan, write, and review code. Here are the details.

Xcode 27 gains Gemini integration

Earlier this year, Apple rolled out Xcode 26.3 with support for agentic coding. In practice, it allowed developers to plug AI tools such as OpenAI’s Codex or Anthropic’s Claude Agent directly into Xcode to help with tasks ranging from writing boilerplate code to updating the entire project based on its own documentation, file structure, and more.

The release also allowed developers to plug in other AI agents via an “Add an Agent…” tool, in addition to exposing Xcode to external agents via MCP.

After that initial rollout, Apple kept iterating on Xcode’s agentic tools and capabilities, including the Xcode 26.5 update, which introduced support for queueing messages in the coding assistant and letting agents “ask clarifying questions to provide more accurate results.”
