• Xcode 15.0 or later
• iOS 17.0 or later
• watchOS 10.0 or later
• Apple Watch (for watch app testing)

1. Clone the repository

   git clone https://github.com/your-username/todo-example.git
   cd todo-example

2. Open in Xcode

   open ToDO.xcodeproj

3. Build and Run

   • Select your target device (iPhone/Apple Watch)
   • Press Cmd + R to build and run

The app uses generic bundle identifiers that you can customize:

• iOS App: com.example.todo
• Watch App: com.example.todo.watchapp
• App Group: group.com.example.todo

The app uses WatchConnectivity framework for bidirectional synchronization:

• Immediate sync when both devices are active
• Background transfer when watch is not reachable
• Conflict resolution based on most recent changes

struct TodoItem: Codable, Identifiable {
    let id: UUID
    var title: String
    var isCompleted: Bool
    var priority: TodoPriority
    var category: TodoCategory
    var createdAt: Date
}

1. Fork the repository
2. Create your feature branch (git checkout -b feature/amazing-feature)
3. Commit your changes (git commit -m 'Add amazing feature')
4. Push to the branch (git push origin feature/amazing-feature)
5. Open a Pull Request
