I want to show all API data into the table view. It only shows the first dictionary element of API

I am fetching data through API and save it into init. When I show this data into table view then it only shows the first value of dictionary. I want to show all the values of dictionary into my table view.

class:

class FetchedDeparment
{
    var depttName: String
    var createdDate: String
    
    init(depttName: String, createdDate: String) {
        
        self.depttName = depttName
        self.createdDate = createdDate
    }
}

Fetching data from API and save it init.

var fetchedDepttData = [FetchedDeparment]()
fetchedDepttData = []

self.arrDeptt = json["departments"] as! [[String : Any]]
print(self.arrDeptt)
                        
for eachDepartment in json["departments"]!
{
    let eachData = eachDepartment as! [String: Any]
    let depttName = eachData["name"] as! String
    let createdDate = eachData["created_at"] as! String
                            
    self.fetchedDepttData.append(FetchedDeparment.init(depttName: depttName, createdDate: createdDate))
}
self.tableView.reloadData()

TableView: This is where I want to show all the data.

func numberOfSections(in tableView: UITableView) -> Int {
        return fetchedDepttData.count
    }
    
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 1
    }

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "DepartmentCell", for: indexPath) as! ShowDepttTVCell
        
        cell.lblDepttName.text = fetchedDepttData[indexPath.row].depttName
        cell.lblCreatedDate.text = fetchedDepttData[indexPath.row].createdDate
        
        return cell
    }

Your code is okay. You have to replace the row with section because you are counted the array in numberOfSection table view data source method.

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "DepartmentCell", for: indexPath) as! ShowDepttTVCell

        cell.lblDepttName.text = fetchedDepttData[indexPath.section].depttName
        cell.lblCreatedDate.text = fetchedDepttData[indexPath.section].createdDate

        return cell
    }
