Xcode 26.3 Lets AI Agents From Anthropic and OpenAI Build Apps Autonomously

Apple's release of Xcode 26.3 with support for agentic coding allows developers to utilize tools like Anthropic's Claude Agent and OpenAI's Codex for autonomous app creation. This update enables Xcode to complete more complex app development tasks, potentially streamlining the development process. For website owners, this means that the apps interacting with their websites may become more sophisticated and autonomous, potentially leading to increased AI bot traffic. As apps built with agentic coding capabilities become more prevalent, website owners may need to reassess their AI bot tracking strategies to account for these more advanced interactions. This could involve updating their llms.txt files to reflect the changing landscape of AI-powered app development. To prepare for this shift, website owners can take several actionable steps: first, review their current llms.txt files to ensure they are up-to-date and accurately reflect the AI bots interacting with their site; second, consider implementing more advanced AI bot tracking tools to better understand the autonomous app interactions; and third, monitor their website's traffic patterns for signs of increased AI bot activity, adjusting their content policies and llms.txt files accordingly.
