During the 2026 Worldwide Developers Conference, Apple made significant upgrades to its integrated development environment (IDE) for a brand-new "ambient programming" development scenario. The latest released core component of Xcode 27 features deep integration of AI agents for the first time, offering developers an unprecedented intelligent programming experience.
According to a special lecture video released by the official source, this AI agent can perfectly understand the Swift language. Developers can simply use natural language conversations to let the AI assist with various complex programming tasks.

Multi-turn Conversation and Cross-file Modification
This AI agent not only supports multi-turn continuous conversation but is also directly embedded in the toolbar, allowing developers to initiate interactions at any time. Even more powerful is its ability to modify entire codebases across files, greatly improving development efficiency.
To offer developers more flexible choices, Xcode 27 also supports integration with third-party mainstream AI models such as Anthropic, OpenAI, and Google. On the technical level, Apple introduced a new Core AI framework and upgraded the open-source framework MLX, allowing on-device AI capabilities to be deeply integrated into the entire development process.
Natural Language Bug Fixing and Autonomous App Building
In practical application scenarios, the AI agent has demonstrated remarkable creativity. It can directly generate application designs and functional ideas based on simple prompts and icons or other resources. Even without any human intervention, it can independently build complete applications.
Once the application is initially built, developers can still use a conversational approach to ask the AI to add backgrounds, effects, animations, and perform multilingual translations. This new interaction mode makes bug fixing and app development as simple and efficient as chatting.
