public struct SwipeData
{
  public float distance; //The distance of the swipe
  public float angle; //The angle of the swipe, 0 is right

If you want to use different event behaviour, like calling a separate event for each direction, you can override OnSwipeDetected in inherited class :

protected override void OnSwipeDetected(SwipeData swipe)
{
    base.OnSwipeDetected(swipe);

    switch (GetMoveDirection(swipe))
    {
        case MoveDirection.Up:
            OnUpSwipe?.Invoke();
            break;
        case MoveDirection.Down:
            OnDownSwipe?.Invoke();
            break;
        case MoveDirection.Left:
            OnLeftSwipe?.Invoke();
            break;
        case MoveDirection.Right:
            OnRightSwipe?.Invoke();
            break;
        default:
            break;
    }
}

Example class SwipeDirectionEventTrigger is provided.
