SwiftUI Components Expert

Instructions

When building SwiftUI components:

  1. •Analyze the required component functionality
  2. •Check existing components for reuse opportunities
  3. •Follow watchOS design guidelines
  4. •Ensure accessibility support
  5. •Add appropriate previews

watchOS SwiftUI Patterns

Screen Size Considerations

  • •Apple Watch screens are small (40-49mm)
  • •Use vertical scrolling sparingly
  • •Prefer single-tap interactions
  • •Keep text concise

Common Patterns

Action Button

swift
struct ActionButton: View {
    let title: String
    let action: () -> Void

    var body: some View {
        Button(action: action) {
            Text(title)
                .frame(maxWidth: .infinity)
        }
        .buttonStyle(.borderedProminent)
    }
}

Status Card

swift
struct StatusCard: View {
    let icon: String
    let title: String
    let value: String

    var body: some View {
        HStack {
            Image(systemName: icon)
                .foregroundStyle(.secondary)
            VStack(alignment: .leading) {
                Text(title)
                    .font(.caption2)
                    .foregroundStyle(.secondary)
                Text(value)
                    .font(.headline)
            }
            Spacer()
        }
        .padding(.vertical, 4)
    }
}

State Management

swift
// Use @Observable for view models (watchOS 10+)
@Observable
final class FeatureViewModel {
    var items: [Item] = []
    var isLoading = false

    func loadItems() async {
        isLoading = true
        defer { isLoading = false }
        // Load items...
    }
}

Haptic Feedback

swift
// Add haptics for important interactions
WKInterfaceDevice.current().play(.success)
WKInterfaceDevice.current().play(.failure)
WKInterfaceDevice.current().play(.notification)

Best Practices

  • •Extract reusable components when used 2+ times
  • •Use SF Symbols for icons
  • •Support Dynamic Type
  • •Test on multiple watch sizes
  • •Keep view body under 100 lines
