A CLI for iOS Automation

Pippin: A Token-Efficient CLI for iOS Automation

Pippin (Simulator Driver) is a command-line interface designed to bridge the gap between Large Language Models (LLMs) and the iOS Simulator. It provides a set of stateless, atomic commands to inspect, interact with, and verify the state of iOS applications running in the Simulator.

Features

• Token Efficiency: Generates simplified, text-based JSON representations of the UI, allowing LLMs to "see" the screen with minimal token usage.
• Stateless Actions: Each command is independent, making it easier for agents to reason about the state.
• Native Wrapper: Orchestrates xcrun simctl and idb for robust automation.

Installation

You can run Pippin directly using uvx (recommended):

uvx pippin --help

Or install it via pip:

pip install pippin

Note: You must have idb (iOS Development Bridge) and Xcode command-line tools installed and configured on your machine.

Usage

Pippin commands follow the structure: pippin [command] [subcommand] [flags]
