[SwiftUI] Picker

1. CaseIterable, Identifiable 프로토콜 채택하는 선택지 enum 생성

enum Sports: String, CaseIterable, Identifiable {
    case soccer = "⚽️"
    case basketball = "🏀"
    case baseball = "⚾️"
    
    var id: Self { self }
}

2. ForEach문으로 Picker 구성

struct Picker_Tutorials: View {
    @State private var selected: Sports = .soccer
    
    var body: some View {
        VStack {
            Text(selected.rawValue)
                .font(.system(size: 200))
            
            Picker("Favorite", selection: $selected) {
                ForEach(Sports.allCases) { item in
                    Text(item.rawValue)
                }
            }
        }
    }
}
