self.items = items
tableView.reloadData()
}

// MARK: - Private methods

private func setupTable() {
tableView.delegate = self

)
}
}

// MARK: - UITableViewDataSource

extension <#Your#>TableViewAdapter: UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return items.count
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(
withIdentifier: String(describing: <#Your#>TableViewCell.self),
for: indexPath
) as? TableViewCell
cell?.backgroundColor = .red
return cell ?? <#Your#>UITableViewCell()
}
}

// MARK: - UITableViewDelegate

<#childView#>.bottomAnchor.constraint(equalTo: <#parentView#>.safeAreaLayoutGuide.bottomAnchor, constant: 0),
<#childView#>.leadingAnchor.constraint(equalTo: <#parentView#>.safeAreaLayoutGuide.leadingAnchor, constant: 0),
<#childView#>.trailingAnchor.constraint(equalTo: <#parentView#>.safeAreaLayoutGuide.trailingAnchor, constant: 0)
])
```

selector: #selector(keyboardWillShow),
name: UIResponder.keyboardWillShowNotification,
object: nil)
NotificationCenter.default.addObserver(self,
selector: #selector(keyboardWillHide),
name: UIResponder.keyboardWillHideNotification,
object: nil)
}

@objc
func keyboardWillShow(notification: NSNotification) {
guard
