Prevent voice over (Accessibility) from announcing UITableViewCell as selected

I asked this as a code level support issue from Apple and got the following solution which works perfectly. Use a custom subclass of UITableViewCell where you override accessibilityTraits as in the following example:

class NoTraitCell: UITableViewCell {
    override var accessibilityTraits: UIAccessibilityTraits {
        get {
            return UIAccessibilityTraitNone
        }
        set {}
    }
}
