Explore the user's existing macOS app projects to understand their patterns and structure. Look in:
1. ~/Apps/macOS/ for any existing macOS apps
2. Check if there are any Swift/macOS patterns being used
3. Look for any existing automation or accessibility-related code

Report back on:
- Existing macOS app structure
- Swift patterns used
- Any relevant code for app control or accessibility


I'll explore the macOS app projects to understand the patterns and structure. Let me start by checking the macOS directories and files.


Bash

find /Users/neog/Apps/macOS -type f -name "*.swift" -o -name "*.pbxproj" -o -name "*.md" 2>/dev/null | head -20

Find Swift files and Xcode projects in macOS apps


ls -la /Users/neog/Apps/macOS 2>/dev/null || echo "Directory not found"

Let me look at more patterns in the existing apps, particularly focusing on automation and app control:


find /Users/neog/Apps/macOS -name "*.swift" -path "*/Models/*" | head -20

Find data models in macOS apps


grep -r "NSWorkspace\|Process\|AppleScript" /Users/neog/Apps/macOS --include="*.swift" 2>/dev/null | head -20
