ios-app-tester

ios-app-tester is a skill for Claude Code from ckorhonen/claude-skills. It costs 50 tokens per session (1,810 once invoked), scanned A, original, MIT.

A command-line tool guide for testing iOS apps in the iOS Simulator, Apple's virtual device environment. It uses accessibility information to inspect screens, automate actions, record tests, and check support for VoiceOver, Apple's screen reader.

In plain words
What is it for?
Use it to tap and swipe through simulator apps, inspect interface elements, audit VoiceOver support, record test videos, script repeatable scenarios, and connect iOS testing to CI/CD pipelines.
Why use it?
It makes simulator testing repeatable and lets you find missing accessibility labels or descriptions. This helps catch interaction and accessibility issues without performing every test manually.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ios-app-tester scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Overview

Test and automate iOS Simulator applications using AXe, a command-line tool that leverages Apple's Accessibility APIs for programmatic simulator control. AXe runs as a single binary with no server setup required.

When to Use

  • Automating iOS Simulator UI interactions for testing
  • Auditing accessibility labels and VoiceOver descriptions
  • Recording test execution videos
  • Scripting repeatable test scenarios
  • CI/CD pipeline iOS testing integration

Prerequisites

  • macOS with Xcode installed
  • iOS Simulator (included with Xcode)
  • Homebrew (for installation)

Installation

brew tap cameroncooke/axe
brew install axe

Verify installation:

axe --help

Quick Start

  1. Find your simulator UDID:
axe list-simulators
  1. Tap a coordinate:
axe tap -x 200 -y 400 --udid <SIMULATOR_UDID>
  1. Inspect accessibility elements:
axe describe-ui --udid <SIMULATOR_UDID>

Command Reference

Simulator Discovery

# List all available simulators with UDIDs
axe list-simulators

Touch Interactions

# Tap at coordinates
axe tap -x 100 -y 200 --udid <UDID>

# Swipe gesture
axe swipe --start-x 100 --start-y 500 --end-x 100 --end-y 200 --udid <UDID>

# Low-level touch events

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
