Supporting Evidence

Xcode Preview Capture Skill

Build SwiftUI views and capture screenshots of their rendered output for visual analysis.

Installation Path

Scripts are located at ${PREVIEW_BUILD_PATH:-$HOME/XcodePreviews}/scripts/

Compatibility: If ~/XcodePreviews doesn't exist, fall back to ~/Claude-XcodePreviews (legacy name). The PREVIEW_BUILD_PATH environment variable overrides both.

Available Commands

Auto-detects project type and uses the best approach:

bash
1"${PREVIEW_BUILD_PATH:-$HOME/XcodePreviews}"/scripts/preview \
2  <path-to-file.swift> \
3  --output /tmp/preview.png

Quick Capture (Current Simulator)

bash
1"${PREVIEW_BUILD_PATH:-$HOME/XcodePreviews}"/scripts/capture-simulator.sh \
2  --output /tmp/preview-capture.png

Xcode Project with #Preview

Fast builds by injecting a minimal PreviewHost target (handled automatically by the unified script):

bash
1"${PREVIEW_BUILD_PATH:-$HOME/XcodePreviews}"/scripts/preview \
2  <path-to-file.swift> \
3  --project <path.xcodeproj> \
4  --output /tmp/preview.png

SPM Package Preview

Auto-detected from Package.swift in parent directories:

bash
1"${PREVIEW_BUILD_PATH:-$HOME/XcodePreviews}"/scripts/preview \
2  <path-to-file.swift> \
3  --output /tmp/preview.png

Standalone Swift File

Build a standalone Swift file with system frameworks only:

bash
1"${PREVIEW_BUILD_PATH:-$HOME/XcodePreviews}"/scripts/preview \
2  <path-to-file.swift> \
3  --output /tmp/preview.png

Workflow

When the user asks to preview a SwiftUI view:

  1. Identify the target: Determine what needs to be previewed (Swift file, project scheme, or current simulator state)

  2. Build and capture: Run the appropriate script

  3. Read and analyze: Use the Read tool to view the captured PNG at /tmp/preview.png

  4. Report findings:

    • Layout: Structure and arrangement
    • Visual elements: Buttons, text, images
    • Styling: Colors, fonts, spacing
    • Issues: Alignment, overflow, accessibility
    • Suggestions: Improvements

Parameters

OptionDescription
--project <path>Xcode project file
--workspace <path>Xcode workspace file
--package <path>SPM Package.swift path
--module <name>Target module (auto-detected)
--simulator <name>Simulator name (default: iPhone 17 Pro)
--output <path>Output screenshot path
--verboseShow detailed build output

Error Handling

  • No simulator booted: Run sim-manager.sh boot "iPhone 17 Pro"
  • Build failure: Show error, suggest fixes, offer to retry
  • Resource bundle crash: The dynamic script auto-includes Tuist and common bundle patterns
  • Missing imports: Check if the target module needs to be added to imports
