Anthropic hsa updated Claude Code for desktop to include native iOS Simulator integration, giving the AI a live view of your app as it builds and tests it. The feature is in public beta and requires Claude Desktop v1.24012.0 or later, plus Xcode with the iOS platform installed.
The workflow allows Claude to build, run, or check an app, and it opens the iOS Simulator in a dedicated pane alongside the conversation. Claude watches the app run, interacts with the interface, and iterates on the code without you having to break the loop. You can keep using the simulator yourself while Claude works, so there’s no handoff friction.
The iOS Simulator pane drives the simulator directly rather than through computer use, the general-purpose approach where an AI controls the screen the way a human would by moving a cursor. Computer use requires macOS Accessibility and Screen Recording permissions, which many developers are understandably reluctant to grant. This integration sidesteps both requirements entirely, making it meaningfully less invasive than comparable AI-driven testing setups. Direct access also makes Claude’s interaction with the simulator more reliable, since computer use is inherently fragile when working from pixel observation.
Here are the requirements to get started with using the Live Simulator:
- Claude Desktop v1.24012.0 or later
- macOS (the feature is Mac-only)
- Xcode with the iOS platform installed
- A local session, the simulator pane is not available in remote or web sessions
Screenshots Claude takes of the simulated device are sent to Anthropic and retained under standard conversation settings. Anthropic specifically advises against signing in to real accounts on a device Claude is controlling. That puts realistic limits on what you’d want Claude poking around in, test credentials and API keys are the obvious concerns.
This lands in the context of Apple formally embracing agentic coding in Xcode 26.3, which added support for Claude Agent and OpenAI’s Codex running directly inside Xcode. Anthropic is clearly moving to cement Claude Code’s position at the tool layer before that system solidifies around a competitor.
