Saving all the rows that have been selected, can be solved like this:

var selectedRows: [Int] = []

override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    self.selectedRows.append(indexPath.row)

    UserDefaults.standard.set(selectedRows, forKey: "selectedRows")
}

Later, use 

if let selectedRows = UserDefaults.standard.array(forKey: "selectedRows") as? [Int] {
    // Do what you want with the selectedRows
}

if you want to get all of the selectedRows back
