import SwiftUI

extension View {

  /// Haptic Feedback
  /// - Parameters:
  ///   - style: Feedback Style
  ///   - type: Feedback Type
  func hapticFeedback(_ style: UIImpactFeedbackGenerator.FeedbackStyle? = nil,
                      type: UINotificationFeedbackGenerator.FeedbackType? = nil) {
    if let style = style {
      let feedback = UIImpactFeedbackGenerator(style: style)
      feedback.impactOccurred()
    } else if let type = type {
      let feedback = UINotificationFeedbackGenerator()
      feedback.notificationOccurred(type)
    } else {
      UIImpactFeedbackGenerator().impactOccurred()
    }
  }
}
