Issue #362

let tapGR = UITapGestureRecognizer(target: self, action: #selector(handleTap(_:)))

@objc private func handleTap(_ gr: UITapGestureRecognizer) {
    didTouch?()
}

We need to use lazy instead of let for gesture to work

lazy var tapGR = UITapGestureRecognizer(target: self, action: #selector(handleTap(_:)))
