A photo gallery app where I can take photos with the camera or choose from my photo library. Display all photos in a grid, and tap to view full screen.

Make sure the app requests camera and photo library permissions when needed. Add appropriate permission descriptions explaining why we need access.

Display photos in a 3-column grid with small gaps between photos. Photos should be square and fill the screen edge-to-edge. Add a subtle animation when new photos are added.

Add a floating "+" button in the bottom right corner. When tapped, show an action sheet with two options:
- "Take Photo" (opens camera)
- "Choose from Library" (opens photo picker)

When I tap a photo in the grid, open it full screen with:
- Black background
- Photo fills the width, centered vertically
- Pinch to zoom
- Swipe left/right to see other photos
- X button to close

In the full screen view, add a trash button that deletes the photo after confirming. Show an alert asking "Delete this photo?" with Cancel and Delete options.

Save all photos locally so they persist when the app is closed and reopened. Store them in the app's documents directory.

When the gallery is empty, show a friendly message:
- A camera icon
- "No photos yet"
- "Tap + to add your first photo"

In the full screen view, add an info button that shows:
- Date photo was added
- Photo dimensions
- File size

Add the ability to create albums:
- Tab bar with "All Photos" and "Albums"
- Albums tab shows list of albums
- Tap to create new album with a name
- Long press photos in grid to select and add to album

In full screen view, add an edit button that opens editing options:
- Rotate left/right
- Crop to square
- Apply filters (black & white, sepia, vivid)
Save edits back to the photo.
