You shouldn't use tap gesture for UIAccessibility ot try to add tap gestures to UIAccessibility.UIAccessibility is meant for the UIElements where the people can see/hear what is on the screen. You cannot add UIAccessiility for tap gesture functions. What you can do is to post a accessibility notification to the user saying tap to perform something. Again, you need to use buttons to perform an action in UIAccessibility.

You can override accessibilityScroll method:

override func accessibilityScroll(_ direction: 
    UIAccessibilityScrollDirection) -> Bool {

    super.accessibilityScroll(direction)

    if direction == UIAccessibilityScrollDirection.left {
    // do your stuff            
    }

    if direction == UIAccessibilityScrollDirection.right {
    // do your stuff        
    }
    return true
}

Add this to your code

overrride func viewDidLoad()
{
super.viewDiDLoad()
let tap = UITapGestureRecognizer(target: self, action: "performTap")
self.view.addGestureRecognizer(tap)
}

And to perform the necessary action, add your required code here

func performTap()
{
   // Perform you action here
}
