Xcode Simulator Test

SkillDev tools

This skill lets your AI test iOS apps in a simulator. Once added, your AI can build and run an iOS app in a simulator, then report back test results with screenshots and logs. It is useful when iOS changes need simulator evidence before handoff.

Available today. Use it from your connected AI after setup.

After adding it, ask your AI to build and run your iOS app in a simulator whenever changes need testing. It will return the results with screenshots and logs for you to review.

Then ask your AI: use the Xcode Simulator Test skill

What your AI can do with it

  • Build an iOS app in a simulator
  • Run an iOS app in a simulator
  • Report test results after a simulator run
  • Attach screenshots to test results
  • Attach logs to test results
  • Provide simulator evidence before handoff

What this skill tells your AI

The instructions your AI receives, as published by everyinc/compound-engineering-plugin in skills/ce-test-xcode/SKILL.md and read by ahel’s review.

Build and exercise an iOS app on a simulator, preserving screenshots, logs, human-verification results, and failures as evidence for the user.

Done:

  • A completed run reports overall PASS, FAIL, or PARTIAL plus project, scheme, simulator, build result, per-surface PASS / FAIL / SKIP, console errors, human checks, and residual failures.
  • Per-surface status is derived from evidence, not the user's routing choice. PASS requires completed passing evidence. FAIL records observed failing evidence until a completed retest replaces it. SKIP means the check has no completed outcome.
  • The overall result is FAIL while any failure remains, PARTIAL when no failure remains but a scoped check is skipped, and otherwise PASS.
  • Any failure before the app is launched with log capture running stops later stages and reports an actionable setup blocker with its evidence.

Boundaries: this skill tests and reports. Diagnosis and any user-approved product fix belong to ce-debug, invoked with its authority narrowed so it returns here without committing, pushing, or opening a PR. Keep simulator interaction within the app and flows the user placed in scope.

Run

  1. Prepare and launch. Read references/setup-and-build.md. It defines the XcodeBuildMCP availability check, project and scheme discovery, simulator choice, build, install, launch, and log-capture start.
  2. Exercise and report. After launch, read references/test-and-report.md. It defines per-screen evidence, human-only flows, the SwiftUI inline-link automation limitation, what to do when a check fails, cleanup, and the fixed summary fields.

Do not replace either required read with remembered tool names. XcodeBuildMCP adapters differ by host, while their observable success conditions do not.
