Öffne Claude Desktop → Settings → Developer → Edit Config. Nach dem Speichern neu starten.

Cursor nutzt das gleiche mcpServers-Schema wie Claude Desktop. Projektkonfiguration schlägt die globale.

      "args": [

Klicken Sie auf das MCP-Servers-Symbol in der Cline-Seitenleiste, dann "Edit Configuration".

~/.codeium/windsurf/mcp_config.json

  }
}

Gleiche Struktur wie Claude Desktop. Windsurf neu starten zum Übernehmen.

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "ios-simulator-skill",
      "command": "git",

        "https://github.com/conorluddy/ios-simulator-skill",
        "~/.claude/skills/ios-simulator-skill"
      ]
    }
  ]
}

Continue nutzt ein Array von Serverobjekten statt einer Map.

In context_servers hinzufügen. Zed lädt beim Speichern neu.

Anwendungsfälle

Praxisnahe Nutzung: ios-simulator-skill

Build, run, and screenshot the current flow

👤 iOS devs using Claude Code to iterate ⏱ ~5 min beginner

Wann einsetzen: You changed a view and want to see it live without leaving the chat.

Voraussetzungen

Xcode + simulator installed — Standard macOS iOS dev setup

Ablauf

Ask Claude to build and run

Use ios-simulator-skill. Build MyApp scheme for iPhone 16, launch, navigate to Settings, screenshot.✓ Kopiert

→ Compact build summary, then the screenshot
Iterate

I tweaked the padding — rebuild and re-screenshot.✓ Kopiert

→ Fast turn with minimal token overhead

Ergebnis: Tight build-iterate-view loop in Claude Code.

Fallstricke

Scheme name typo causes unclear error — Skill returns a compact list of available schemes on mismatch

Kombinieren mit: filesystem

Drive a scripted UI flow for smoke testing

👤 iOS devs and QA ⏱ ~15 min intermediate

Wann einsetzen: You want to verify a critical flow without writing full XCUITest scaffolding.

Ablauf

Describe the flow

Launch the app, tap 'Sign in', enter creds, tap the first row in the list, screenshot.✓ Kopiert

→ Claude uses accessibility labels to drive each step
Check WCAG compliance

Now run the accessibility audit on the current screen.✓ Kopiert

→ WCAG findings with fix suggestions

Ergebnis: A working smoke flow plus an a11y pass.

Fallstricke

Flow breaks when a label changes — Labels are more stable than coordinates, but still review after big UI refactors

Tail logs while reproducing a bug

👤 iOS devs chasing a flaky issue ⏱ ~10 min intermediate

Wann einsetzen: A bug only repros in the simulator and you want the relevant logs.

Ablauf

Reproduce with filtered logs

Launch the app, tap through the crashing flow, tail logs filtered to error+warning.✓ Kopiert

→ Claude returns a trimmed log bundle and highlights the likely cause

Ergebnis: A targeted log excerpt and a hypothesis for the bug.

Fallstricke

Logs too noisy if severity filter not set — Default to error+warning; raise to info only when debugging

Kombinationen

Mit anderen MCPs für 10-fache Wirkung

ios-simulator-skill + filesystem

Skill runs the build; filesystem reads/writes the sources

Edit SettingsView.swift, then build and screenshot.✓ Kopiert

ios-simulator-skill + github

Reproduce an issue from a GitHub bug report in the simulator

Read issue #42, reproduce the steps in the simulator, attach screenshot to a comment.✓ Kopiert

Werkzeuge

Was dieses MCP bereitstellt

Werkzeug	Eingaben	Wann aufrufen
xcodebuild wrapper	scheme, destination	Any build request
Simulator driver (accessibility APIs)	element label/role + action	UI automation in the simulator
Screenshot capture	none (current screen)	Visual verification
Log tailing	severity filter, duration	Debugging runtime issues
Device lifecycle	boot/shutdown/create/reset	Fresh simulator state needed
Accessibility audit	current screen	A11y review

Kosten & Limits

Was der Betrieb kostet

API-Kontingent: None
Tokens pro Aufruf: Very low — compact build summaries + compressed screenshots are the main design goal
Kosten in €: Free — skill is local
Tipp: Keep screenshots at default compression; full-res screens eat context fast.

Sicherheit

Rechte, Secrets, Reichweite

Credential-Speicherung: No credentials in the skill. App-side secrets stay in your build config.

Datenabfluss: None — everything runs on local simulators

Simulators have access to your keychain if you've configured it — be careful with credentials during automation.

Fehlerbehebung

Häufige Fehler und Lösungen

'No such scheme'

Skill lists available schemes on mismatch; pick the exact name.

Prüfen: xcodebuild -list -project MyApp.xcodeproj

Accessibility label not found

Add accessibilityIdentifier to the SwiftUI view — it's more stable than the visible label.

Simulator stuck booting

Use the device-lifecycle reset command; then re-boot.

Prüfen: xcrun simctl list

Alternativen

ios-simulator-skill vs. andere

Alternative	Wann stattdessen	Kompromiss
Direct xcodebuild + simctl	You don't mind the token bloat from raw output	No abstraction; verbose
XcodeBuildMCP	You prefer an MCP server with structured tools	MCP route; this skill is local scripts
