Apple Releases Xcode 26.3 With AI Agents Support | DeviceDecode
Apple has officially released Xcode 26.3 after several weeks of testing. The new update brings powerful AI tools directly into Xcode, making app development easier and faster for developers.
With this update, developers can now use AI agents like Claude from Anthropic and Codex from OpenAI inside Xcode.
What’s New in Xcode 26.3?
Xcode 26.3 now supports agent-based coding. This means AI can handle more complex tasks on its own while helping developers build apps.
The AI agents can:
- Create new files
- Understand and review project code
- Build apps directly
- Run tests automatically
- Take image snapshots to check their work
- Access Apple’s latest developer documentation
Apple worked closely with Anthropic and OpenAI to make sure their AI models work smoothly with all Xcode features.
Support for Open Standards
Besides Claude and Codex, Xcode 26.3 also supports any AI tool that uses the open standard Model Context Protocol. This gives developers more flexibility to use different AI solutions.
Availability
Xcode 26.3 is now available for download from Apple’s official developer website.
