To create a SwiftUI view, you can start by understanding the fundamentals of SwiftUI, which are declarative, compositional, and state-driven. Here's a simple example of a SwiftUI view:

import SwiftUI

struct ContentView: View {
    @State private var isAwarded: Bool = false

    var body: some View {
        VStack {
            Text("Pet Competition")
                .font(.largeTitle)
                .padding()

            List {
                ForEach(pets) { pet in
                    HStack {
                        Text(pet.name)
                        Spacer()
                        if pet.hasAward {
                            Image(systemName: "star.fill")
                                .foregroundColor(.yellow)
                        }
                    }
                    .swipeActions {
                        Button("Award") {
                            awardPet(pet)
                        }
                        .tint(.green)
                    }
                }
            }
        }
    }

    func awardPet(_ pet: Pet) {
        // Logic to award the pet
    }
}

struct Pet: Identifiable {
    let id = UUID()
    let name: String
    var hasAward: Bool
}

let pets = [
    Pet(name: "Sheldon", hasAward: false),
    Pet(name: "Fluffy", hasAward: true)
]

This example demonstrates a simple list of pets where you can swipe to award them. The view is state-driven, meaning it updates automatically when the state changes, such as when a pet is awarded.

For more advanced SwiftUI capabilities, you can explore creating custom layouts, using animations, and even applying custom Metal shaders to views. SwiftUI also allows you to build entire apps using scenes, which are declarative structures that define the app's UI.

For more detailed information, you can refer to the SwiftUI essentials session from WWDC 2024, which covers the fundamentals of views and their capabilities.
