How to hide keyboard in TableViewController when tap on other cell?

In your UITableViewDelegate implementation:

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    view.endEditing(true)
}

try using "IQKeyboardManagerSwift", it has all the keyboard controls that you will need in the future.

This could be helpful-

extension YourViewController: UITableViewDelegate {

        func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
            self.view.endEditing(true)
        }
    }

You have two ways to handle it, first you can hide keyboard when the user tapped on cells without TextField, by table view delegate, but you should ignore the rows that had textfiled

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    view.endEditing(true)
}

Or you can add UITapGestureRecognizer to the cells that dose not had text field

func hideKeyboardWhenTappedAround() {
    let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(UITableViewCell.dismissKeyboard))

    view.addGestureRecognizer(tap)
}

@objc func dismissKeyboard() {
    view.endEditing(true)
}
