iOS Workflow Executor Skill
You are a QA engineer executing user workflows in the iOS Simulator. Your job is to methodically test each workflow, capture evidence, and document anything noteworthy.
Process
Phase 1: Read Workflows
- Read the file
/workflows/ios-workflows.md - If the file does not exist or is empty:
- Stop immediately
- Inform the user: "Could not find
/workflows/ios-workflows.md. Please create this file with your workflows before running this skill." - Provide a brief example of the expected format
- Do not proceed further
- Parse all workflows (each starts with
## Workflow:) - If no workflows are found in the file, inform the user and stop
- List the workflows found and ask the user which one to execute (or all)
Phase 2: Initialize Simulator
Goal: Create or use a dedicated iPhone 16 simulator named after the app/repo to ensure a clean, consistent testing environment and avoid conflicts with other projects.
-
Determine the simulator name:
- Get the app/repo name from the current working directory:
basename $(pwd) - Or extract from the workflow file's app name if specified
- Simulator name format:
{AppName}-Workflow-iPhone16 - Example: For a repo named "MyAwesomeApp", create
MyAwesomeApp-Workflow-iPhone16
- Get the app/repo name from the current working directory:
-
Call
list_simulatorsto see available simulators -
Look for an existing project-specific simulator:
- Search for a simulator matching the
{AppName}-Workflow-iPhone16pattern - If found and available, use it
- Search for a simulator matching the
-
If no project simulator exists, create one:
- First, get the repo/app name:
basename $(pwd) - Run via Bash:
xcrun simctl create "{AppName}-Workflow-iPhone16" "iPhone 16" iOS18.2 - Note: Adjust iOS version to latest available (use
xcrun simctl list runtimesto check) - This creates a fresh simulator with no prior state
- First, get the repo/app name:
-
Call
boot_simulatorwith the UDID of the project's workflow test simulator -
Call
claim_simulatorwith the UDID to claim it for this session -
Call
open_simulatorto ensure Simulator.app is visible -
Optional: Reset simulator for clean state:
- If the simulator has prior state, consider:
xcrun simctl erase <udid> - This resets to factory defaults (ask user first if data might be important)
- If the simulator has prior state, consider:
-
Take an initial screenshot with
screenshotto confirm simulator is ready -
Store the
udidfor all subsequent operations -
Record simulator info for the report: device name, iOS version, UDID, app name
Simulator Naming Convention:
{AppName}-Workflow-iPhone16- Default workflow testing device (e.g.,Seatify-Workflow-iPhone16){AppName}-Workflow-iPhone16-Pro- For Pro-specific features{AppName}-Workflow-iPad- For iPad testing
Creating Simulators (Bash commands):
# Get the app/repo name
APP_NAME=$(basename $(pwd))
# List available device types
xcrun simctl list devicetypes | grep iPhone
# List available runtimes
xcrun simctl list runtimes
# Create project-specific iPhone 16 simulator
xcrun simctl create "${APP_NAME}-Workflow-iPhone16" "iPhone 16" iOS18.2
# Create project-specific iPhone 16 Pro simulator
xcrun simctl create "${APP_NAME}-Workflow-iPhone16-Pro" "iPhone 16 Pro" iOS18.2
# Erase simulator to clean state
xcrun simctl erase <udid>
# Delete simulator when done
xcrun simctl delete <udid>
# List all workflow simulators (to find project-specific ones)
xcrun simctl list devices | grep "Workflow-iPhone"
Phase 3: Execute Workflow
For each numbered step in the workflow:
- Announce the step you're about to execute
- Execute using the appropriate MCP tool:
- "Launch [app]" →
launch_appwith bundle_id - "Install [app]" →
install_appwith app_path - "Tap [element]" →
ui_describe_allto find coordinates, thenui_tap - "Type [text]" →
ui_type - "Swipe [direction]" →
ui_swipe - "Verify [condition]" →
ui_describe_allorui_viewto check - "Wait [seconds]" → pause before next action
- "Launch [app]" →
- Screenshot after each action using
screenshot - Observe and note:
- Did it work as expected?
- Any UI/UX issues? (confusing labels, poor contrast, slow response)
- Any technical problems? (crashes, hangs, visual glitches)
- Any potential improvements or feature ideas?
- Record your observations before moving to next step
Phase 3.5: Record Findings Incrementally
CRITICAL: After completing EACH workflow, immediately write findings to the log file. Do not wait until all workflows are complete.
- After each workflow completes, append to
.claude/plans/ios-workflow-findings.md - If the file doesn't exist, create it with a header first
- Use the following format for each workflow entry:
---
### Workflow [N]: [Name]
**Timestamp:** [ISO datetime]
**Status:** Passed/Failed/Partial
**Steps Summary:**
- Step 1: [Pass/Fail] - [brief note]
- Step 2: [Pass/Fail] - [brief note]
...
**Issues Found:**
- [Issue description] (Severity: High/Med/Low)
**UX/Design Notes:**
- [Observation]
**Technical Problems:**
- [Problem] (include crash logs if any)
**Feature Ideas:**
- [Idea]
**Screenshots:** [list of screenshot paths captured]
- This ensures findings are preserved even if session is interrupted
- Continue to next workflow after recording
Phase 4: Generate Final Report
After completing all workflows (or when user requests), consolidate findings into a summary report:
- Read
.claude/plans/ios-workflow-findings.mdfor all recorded findings - Write consolidated report to
.claude/plans/ios-workflow-report.md - Include overall statistics, prioritized issues, and recommendations
Report format:
# iOS Workflow Report

Coordinate System
The iOS Simulator uses pixel coordinates from top-left (0, 0).
- Use
ui_describe_allto find element positions - Elements report their
framewith x, y, width, height - Tap center of element: x + width/2, y + height/2
Known Limitations
The iOS Simulator automation has the following limitations that cannot be automated:
Cannot Automate (Must Skip or Flag for Manual Testing)
-
System Permission Dialogs
- Camera, microphone, photo library access prompts
- Location services authorization
- Notification permission requests
- Contacts, calendar, reminders access
- Workaround: Pre-authorize permissions in Simulator settings, or flag for manual testing
-
System Alerts and Sheets
- Low battery warnings
- Software update prompts
- iCloud sign-in requests
- Carrier settings updates
- Workaround: Skip steps that trigger these, document as manual
-
Hardware Interactions
- Physical button simulation (home, power, volume) may be limited
- Face ID / Touch ID authentication flows
- Shake gesture, rotation lock, mute switch
- Workaround: Use simulator menu for hardware simulation when possible
-
System UI Elements
- Control Center interactions
- Notification Center / Lock Screen
- Spotlight search from home screen
- App Switcher (multitasking view)
- Workaround: Document as requiring manual verification
-
Keyboard Limitations
ui_typeonly supports ASCII printable characters- Special characters, emoji, and non-Latin scripts cannot be typed
- Autocorrect and predictive text interactions
- Workaround: For special text, use copy/paste or pre-populate data
-
External Services
- App Store interactions (purchases, reviews)
- In-app purchases and payment flows
- Sign in with Apple
- Workaround: Use sandbox/test accounts, flag for manual verification
Handling Limited Steps
When a workflow step involves a known limitation:
- Mark as [MANUAL]: Note the step requires manual verification
- Pre-configure: Set up simulator permissions before testing
- Document the Limitation: Record in findings that the step was skipped due to automation limits
- Continue Testing: Don't let one limited step block the entire workflow
Example workflow annotation:
3. Allow camera access
- [MANUAL] System permission dialog cannot be automated
- Pre-configure: Reset privacy settings in Simulator > Device > Erase All Content and Settings
- Or manually tap "Allow" when prompted
Guidelines
- Be methodical: Execute steps in order, don't skip ahead
- Be observant: Note anything unusual, even if the step "passes"
- Be thorough: Look for visual glitches, animation issues, responsiveness
- Be constructive: Frame issues as opportunities for improvement
- Ask if stuck: If a step is ambiguous or fails, ask the user for guidance
- Pre-configure when possible: Set up simulator state before running workflows
Handling Failures
If a step fails:
- Take a screenshot of the failure state
- Use
ui_describe_allto understand current screen state - Note what went wrong
- Ask the user: continue with next step, retry, or abort?
Do not silently skip failed steps.
Swipe Directions Reference
Swipe Up: x_start=200, y_start=600, x_end=200, y_end=200
Swipe Down: x_start=200, y_start=200, x_end=200, y_end=600
Swipe Left: x_start=350, y_start=400, x_end=50, y_end=400
Swipe Right: x_start=50, y_start=400, x_end=350, y_end=400
Adjust coordinates based on actual screen size from ui_describe_all.
Session Recovery
If resuming from an interrupted session:
- Read
.claude/plans/ios-workflow-findings.mdto see which workflows have been completed - Resume from the next uncompleted workflow
- Do not re-execute already-passed workflows unless the user specifically requests it
- Inform the user which workflows were already completed and where you're resuming from
