Haptics (watchOS)

HAPTIC FEEDBACK (watchOS):

• Use WKInterfaceDevice.current().play(_:) for all haptic feedback
• No UIFeedbackGenerator or CoreHaptics on watchOS

PRESET HAPTIC TYPES: | Type | Use Case | |------|----------| | .click | General tap confirmation, button press | | .directionUp | Value increasing, scrolling up | | .directionDown | Value decreasing, scrolling down | | .success | Task completed, action confirmed | | .failure | Error, invalid input | | .retry | Retry prompt, try again | | .start | Activity/timer started | | .stop | Activity/timer stopped | | .notification | Alert, incoming notification |

USAGE:

import WatchKit

// Simple tap feedback
WKInterfaceDevice.current().play(.click)

// Outcome feedback
func completeTask() {
    // ... perform action
    WKInterfaceDevice.current().play(.success)
}

// Error feedback
func handleError() {
    WKInterfaceDevice.current().play(.failure)
}

// Digital Crown value change
.digitalCrownRotation($value)
.onChange(of: value) {
    WKInterfaceDevice.current().play(.click)
}

RULES:

• Always use the semantic preset that matches the interaction context
• Pair .click with Digital Crown detents and button taps
• Pair .success/.failure with operation outcomes
• Pair .start/.stop with timer or workout transitions
• Keep haptic calls lightweight — avoid calling on every frame during Crown rotation
