# QA — Visual Validation via iOS Simulator

Validate changes by building, installing, and inspecting the app in the
iOS Simulator using the `ios-simulator` MCP server.

## Prerequisites

The iOS Simulator must be booted before starting. Use
`mcp__ios-simulator__get_booted_sim_id` to confirm. If no simulator is
booted, use `mcp__ios-simulator__open_simulator` first.

## Workflow

1. **Regenerate the Tuist project** so the workspace reflects any file
   changes:

       tuist generate --no-open

2. **Build for simulator** using the workspace (required for
   dependency resolution):

       xcodebuild build -workspace Ruckus.xcworkspace -scheme Ruckus \
         -destination 'platform=iOS Simulator,name=iPhone 17 Pro'

   This uses Xcode's default DerivedData location. If the build fails,
   fix the errors before continuing.

3. **Find the built `.app` bundle.** After a successful build, locate
   it in Xcode's DerivedData:

       find ~/Library/Developer/Xcode/DerivedData \
         -name "Ruckus.app" \
         -path "*/Debug-iphonesimulator/*" \
         -maxdepth 5 \
         -newer Ruckus.xcworkspace \
         2>/dev/null | head -1

   Use the most recently modified match.

4. **Install the app.**

   Use `mcp__ios-simulator__install_app` with the `.app` path found
   in the previous step.

5. **Launch the app.**

   Use `mcp__ios-simulator__launch_app` with `bundle_id: io.defn.Ruckus`
   and `terminate_running: true` to ensure a fresh start.

6. **Take a screenshot and describe the UI.**

   - Use `mcp__ios-simulator__screenshot` to capture the current state.
   - Use `mcp__ios-simulator__ui_describe_all` to get the accessibility
     tree for the visible screen.
   - Read the screenshot to visually inspect the result.

7. **Navigate to the relevant screen.** If the change is not on the
   initial screen, use taps, swipes, and text input to navigate there:
   - `mcp__ios-simulator__ui_tap` — tap coordinates
   - `mcp__ios-simulator__ui_swipe` — scroll or swipe
   - `mcp__ios-simulator__ui_type` — enter text

   After each navigation action, take another screenshot and describe
   the UI to confirm you reached the right screen.

8. **Validate the change.** Compare what you see against the expected
   behavior:
   - Does the UI reflect the change?
   - Are labels, colors, and layout correct?
   - Is the accessibility tree reasonable?

   Report your findings — what looks correct and what (if anything)
   looks wrong.

9. **If something is wrong,** describe the issue clearly. Do NOT
   attempt to fix it automatically unless the caller asks you to.

## Tips

- When you don't know the coordinates of a UI element, use
  `mcp__ios-simulator__ui_describe_all` to find it in the accessibility
  tree — elements include their frame coordinates.
- Take screenshots liberally. They are the ground truth for visual QA.
- If the app crashes on launch, check the build logs and simulator
  system log for clues.
