After several weeks of testing, Apple today released Xcode 26.3, an update that allows developers to use tools like Anthropic's Claude Agent and OpenAI's Codex for app creation directly in Xcode. With support for agentic coding, Xcode can complete more complex app development tasks autonomously. Apple worked with Anthropic and OpenAI to configure their agents for use in Xcode and to ensure that AI models can access a full range of Xcode features.
