A command for building and testing an iOS application with Xcode, Apple’s development tool. It finds the project or workspace, selects a scheme and simulator, then reports build and test results.

Use it to build an iOS app, run its tests on a simulator, and identify failed tests, build errors, warnings, and their file locations.

It collects the project setup and test steps in one workflow instead of requiring you to run them separately.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

git clone --depth 1 https://github.com/SethCalkins/claude-ios-swift-plugin

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.

Model	Per session	Once invoked
Fable 5	$0.00016	$0.00620
Opus 5	$0.00008	$0.00310
Sonnet 5	$0.00003	$0.00124
Haiku 4.5	$0.00002	$0.00062

Security

Grade A, and why

xcode-test 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 4d 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.

Xcode Build and Test

Build and run tests for the iOS project using XcodeBuildMCP.

Instructions

Detect project configuration:
- Look for .xcworkspace first (prefer workspace over project)
- Fall back to .xcodeproj if no workspace
- Read scheme list if scheme not specified
Set session defaults:
- Call mcp__XcodeBuildMCP__session-set-defaults with:
  - workspacePath or projectPath
  - scheme (from argument or auto-detect main app scheme)
  - configuration: "Debug"
Find or boot simulator:
- Call mcp__XcodeBuildMCP__list_sims to find booted simulators
- If --simulator NAME provided, find matching simulator
- If none booted, suggest user boot one or use most recent
Build the project:
- Call mcp__XcodeBuildMCP__build_sim
- Report any build errors with file locations
- If build fails, provide actionable suggestions
Run tests:
- Call mcp__XcodeBuildMCP__test_sim
- Capture test results
- Report failures with:
  - Test name
  - Failure reason
  - File and line number
Summary:
- Total tests run
- Passed / Failed / Skipped counts
- Build time
- Any warnings worth noting

Output Format

## Xcode Test Results

### Configuration
- Workspace: MyApp.xcworkspace
- Scheme: MyApp
- Simulator: iPhone 16 Pro (iOS 18.0)

### Build: SUCCESS (12.3s)
- 2 warnings (see details)

### Tests: 45 passed, 2 failed, 1 skipped

#### Failures
1. `testUserLogin` in `AuthTests.swift:42`
   - Expected true, got false
   - Assertion: User should be authenticated after valid login

2. `testDataSync` in `SyncTests.swift:88`
   - Timeout after 10s
   - Network mock may not be configured

### Warnings
- `ViewModel.swift:15` - 'async' call in actor-isolated context

Tips

Use --simulator "iPhone 16 Pro" to target a specific device
If macOS tests fail due to deployment target, try iOS simulator tests
For CI, ensure a simulator is booted before running

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.
