}
]
}
as you see in response i have three array and i am fetching inspections_overdue_data array i fetched successfully but not able to display on tableview
Here is my code
Code
func OverdueList(){
let preferences = UserDefaults.standard
let uid = "u_id"
let acTkn = "acc_tkn"
let u_ID = preferences.object(forKey: uid)
let A_Token = preferences.object(forKey: acTkn)
let params = ["user_id": u_ID!, "access_token": A_Token!]
print(params)
Alamofire.request(inspectionsList, method: .post, parameters: params).responseJSON(completionHandler: {(response) in
switch response.result{
case.success(let value):
let json = JSON(value)
print(json)
let data = json["inspections_overdue_data"]
print(data)
if data == []{
self.viewNodata.isHidden = false
}else{
data.array?.forEach({ (iunOverDue) in
let iOveList = OvedueModel(surveyor_id: iunOverDue["surveyor_id"].stringValue, country: iunOverDue["country"].stringValue, time: iunOverDue["time"].stringValue, address2: iunOverDue["address2"].stringValue, notes: iunOverDue["notes"].stringValue, house_num: iunOverDue["house_num"].stringValue, name: iunOverDue["name"].stringValue, address1: iunOverDue["address1"].stringValue, eircode: iunOverDue["eircode"].stringValue, date_inspected: iunOverDue["date_inspected"].stringValue, property_id: iunOverDue["property_id"].stringValue, county: iunOverDue["county"].stringValue, client_id: iunOverDue["client_id"].stringValue)
print(iOveList)
self.overDueData.append(iOveList)
})
self.tblOvedue.reloadData()
}
case.failure(let error):
print(error.localizedDescription)
}
})
}
i also added delegate and datasource through storyboard but still i am not able to show data here is my tableview methods
func numberOfSections(in tableView: UITableView) -> Int {
return 0
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return overDueData.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell") as! OverDueTableViewCell
let name = overDueData[indexPath.row].name
let address1 = overDueData[indexPath.row].address1
cell.lblTitle.text = "\(name) \(address1)"
return cell
}

Answer 1

numberOfSections is returning 0, you have to return at least 1 if you want to see anything.
Protip: If you only have 1 section, you can omit it since 1 is the default return value.

Answer 2

You should either remove below tableview's delegate method or you should return at-least 1.
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
