What are the "success" and "failure" vibration patterns in Apple Watch, and iPhone 7 haptic?

Question

I want to imitate the Apple Watch "success" and "failure" vibration patterns in my custom app.

Does anyone have the following information for the various user experiences

• Intensity
• Timing
• Pattern
• (direction?)
• ???

Answer 1

In watchOS Human Interface Guidelines apple provide audio of "success" and "failure" vibration. https://developer.apple.com/watchos/human-interface-guidelines/interactions/#haptic-feedback

Apple watch use hardware they call taptic engine. Vibration is generated by linear repeating moving.

Standard haptic feedback patterns are now exposed in iOS 10. Here are some examples in C#/Xamarin

    #region Override Methods
    public override void ViewDidLoad()
    {
        base.ViewDidLoad();
        // Perform any additional setup after loading the view, typically from a nib.
    }
    #endregion

    #region Custom Actions
    partial void ImpactAction(Foundation.NSObject sender)
    {
        // Initialize feedback
        var impact = new UIImpactFeedbackGenerator(UIImpactFeedbackStyle.Heavy);
        impact.Prepare();

        // Trigger feedback
        impact.ImpactOccurred();
    }

    partial void NotificationAction(Foundation.NSObject sender)
    {
        // Initialize feedback
        var notification = new UINotificationFeedbackGenerator();
        notification.Prepare();

        // Trigger feedback
        notification.NotificationOccurred(UINotificationFeedbackType.Error);
    }

    partial void SelectionAction(Foundation.NSObject sender)
    {
        // Initialize feedback
        var selection = new UISelectionFeedbackGenerator();
        selection.Prepare();

        // Trigger feedback
        selection.SelectionChanged();
    }
    #endregion
