This project focuses on exactly that: a launcher with global hotkey toggle, paged app grid, folder management, drag sorting, and fast local search.\n\n## Demo\n![Main Interface](./Example.png)\n\n## Search Keywords\n\nLaunchpad alternative, macOS app launcher, SwiftUI launcher, AppKit launcher, global hotkey launcher, macOS Tahoe Launchpad replacement, Homebrew Cask app scanner\n\n## What It Does (Aligned With Current Code)\n\n- Runs in a floating launcher window and can be toggled globally with `Cmd + L`\n- Uses a responsive grid with dynamic rows/columns (5-9 columns, 3-7 rows)\n- Supports drag reorder, folders, folder rename, and drag-out from expanded folders\n- Searches by app name, bundle ID, and app path (case-insensitive)\n- Scans system, user, and Homebrew app locations\n- Resolves app icons through workspace icon, metadata fallback, and generated fallback icon\n\n## Controls\n\n| Input | Behavior |\n| --- | --- |\n| `Cmd + L` | Toggle launcher visibility globally |\n| `Cmd + W` | Hide launcher window |\n| `Cmd + Q` | Quit app |\n| `Esc` | Exit edit mode -\u003e close folder -\u003e clear search -\u003e hide window |\n| `Left` / `Up` | Previous page |\n| `Right` / `Down` | Next page |\n| Trackpad scroll gesture | Page switch with threshold and cooldown |\n| Mouse wheel | Page switch with notch accumulation + debounce |\n\n## App Discovery Paths\n\n| Path | Recursive |\n| --- | --- |\n| `/System/Applications` | No |\n| `/System/Applications/Utilities` | No |\n| `/Applications` | No |\n| `/Applications/Utilities` | No |\n| `~/Applications` | No |\n| `/opt/homebrew/Caskroom` | Yes |\n\nThe scanner also filters a set of hidden/background system apps and deduplicates apps using a stable identifier (`bundleID`, or path when `bundleID` is missing).\n\n## Folder and Layout Behavior\n\n- Long press any icon to enter edit mode\n- Drag app onto app to create a folder (`New Folder` by default)\n- Drag app onto folder to add it\n- Reorder apps inside an expanded folder\n- Drag app out of expanded folder to remove it\n- Folder is removed automatically if only one app remains\n- Reset layout clears saved custom order and folders, then restores alphabetical order\n\n## Icon Pipeline\n\n- Resolve symlink/canonical bundle path first\n- Use `NSWorkspace` icon if it is not the generic app icon\n- If generic icon is returned, load icon from bundle metadata (`CFBundleIconFile`, `CFBundleIconName`, etc.)\n- If metadata icon is still unavailable, generate a consistent initials-based fallback icon\n- Cache resized icons asynchronously and preload adjacent pages for smoother pagination\n\n## Persistence\n\nLaunchpad_Back stores layout state in `UserDefaults`:\n\n- `launchpad_item_order`\n- `launchpad_folders`\n\n## Project Structure\n\n```text\nLaunchpad_Back/\n├── Launchpad_BackApp.swift\n├── ContentView.swift\n├── Models/\n│   └── AppItem.swift\n├── Services/\n│   ├── AppIconCache.swift\n│   ├── AppIconResolver.swift\n│   ├── AppLauncherService.swift\n│   ├── AppScannerService.swift\n│   ├── GestureManager.swift\n│   ├── GridLayoutManager.swift\n│   ├── KeyboardEventManager.swift\n│   └── Logger.swift\n├── ViewModels/\n│   ├── EditModeManager.swift\n│   ├── LaunchpadViewModel.swift\n│   ├── PaginationViewModel.swift\n│   └── SearchViewModel.swift\n├── Views/\n│   ├── AppIconView.swift\n│   ├── BackgroundView.swift\n│   ├── FolderExpandedView.swift\n│   ├── PageIndicatorView.swift\n│   └── SearchBarView.swift\n└── Assets.xcassets/\n```\n\n## Requirements\n\n- macOS 15.6 or later\n- Xcode 26.0 or later\n\n## Build\n\n1. Clone the repository:\n\n   ```bash\n   git clone https://github.com/EricYang801/Launchpad_Back.git\n   cd Launchpad_Back\n   ```\n\n2. Open in Xcode:\n\n   ```bash\n   open Launchpad_Back.xcodeproj\n   ```\n\n3. Build and run:\n\n- Select `My Mac`\n- Press `Cmd + R`\n\nOr build from Terminal:\n\n```bash\nxcodebuild build -scheme Launchpad_Back -destination 'platform=macOS'\n```\n\n## Tests\n\nRun unit tests:\n\n```bash\nxcodebuild test -scheme Launchpad_Back -destination 'platform=macOS' -only-testing:Launchpad_BackTests\n```\n\nCurrent test suite covers:\n\n- icon resolution for direct path, symlink path, metadata fallback, and generated fallback icons\n- icon cache behavior for canonical paths, concurrent requests, and in-flight async request joining\n- folder creation/add/remove/delete and saved-order restore\n- reset layout behavior\n- search matching by app name, bundle ID, and path\n- pagination slicing, bounds checks, and page validation\n- basic `SearchViewModel` behavior\n\n## License\n\nThis project is licensed under GPL-3.0.
