this is my Api response '{ response = { code = 200; radioList = ( { "genre_name" = ( { "genre_id" = 1; "genre_name" = Country; } ); "radio_des" = "Lee Brice - Love Like Crazy "; "radio_fev" = 1; "radio_id" = 30; "radio_img" "https://dousic.com/uploads/s48937q.png"; "radio_tags" = ".977 Country"; "radio_title" = "Lee Brice - Love Like Crazy"; "radio_url"="http://7579.live.streamtheworld.com:3690/977_COUNTRY_SC"; },' — Pooja Srivastava, Sep 26 '17 at 09:57
Please provide code for your tableview delegate methods, also check your response by printing self.array_RadioList after this line `self.array_RadioList = resData as! [[String:AnyObject]]` — Anand Yadav, Sep 26 '17 at 10:03
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { let cell : homeCell = tableView.dequeueReusableCell(withIdentifier: "homeCell")! as! homeCell var dict = array_RadioList[(indexPath as NSIndexPath).row] cell.lbl_name?.text = dict["radio_title"] as? String return cell } — Pooja Srivastava, Sep 26 '17 at 10:06

Just create a radio list variable like this 

    var array_RadioList:[JSON]?

Get array from json like this    
-
    if let resData = json["response"]["radioList"].array {
                    self.array_RadioList = resData
                    self.tableView.reloadData()
                }
and reload data.And get radio object in 

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell: UITableViewCell? = self.tableView.dequeueReusableCell(withIdentifier: cellReuseIdentifier)
        let radio:JSON? = array_RadioList?[indexPath.row]
        cell?.textLabel?.text = radio?["radio_tags"].string
        return cell ?? UITableViewCell()
    }

self.array_RadioList = resData as! [[String:Any]] how to write this line it's getting error Cast from'[JSON] to unrelated type '[[String :Any]]' always fails – Pooja Srivastava Sep 26 '17 at 10:51
Why are you casting this with [String:Any]?. – Pardeep Bishnoi Sep 26 '17 at 10:57
Just create ---- var array_RadioList: [JSON]? and pass resData to array_RadioList – Pardeep Bishnoi Sep 26 '17 at 10:59
And use "let radio = array_RadioList?[indexPath.row]" in cellForRowAt for getting radio object. – Pardeep Bishnoi Sep 26 '17 at 11:02
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { return array_RadioList! .count } give this error – Pooja Srivastava Sep 26 '17 at 11:24
Thanks you @Pradeep . – Pooja Srivastava Sep 26 '17 at 12:04

If the API you're calling is well-made, you should use a get method, not a post. Also, I tried to use "https://dousic.com/api/radiolist?user_id=16" but it return

{
    "response": {
        "code": "301",
        "error": "wrong url"
    }
}

These 2 things could be your problem, or it could be in your custom cells, or in you cellforrow method... If you can show more code it would help.

EDIT

Try to use this version of the optional chaining :

if let resData = json["radioList"].arrayObject as? [[String:AnyObject] {
    self.array_RadioList = resData
    self.tbl_home.reloadData()
}

and try to debug it with breakpoints to see if the application goes everywhere you want and what are your variables at this time.

How to use parameters in get method . – Pooja Srivastava Sep 26 '17 at 10:11
{ response = { code = 301; error = "wrong url"; }; } getting this error after using .GET – Pooja Srivastava Sep 26 '17 at 10:24
do you know if you go in this : if self.array_RadioList.count > 0 { self.tbl_home.reloadData() } – Damien Sep 26 '17 at 10:25
Show me 0 element .@Damien Bannerot – Pooja Srivastava Sep 26 '17 at 10:27

If you are getting your array_RadioList from Api_call(), try this

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { let cell : homeCell = tableView.dequeueReusableCell(withIdentifier: "homeCell")! as! homeCell cell.lbl_name?.text = array_RadioList[indexPath.row]["radio_title"] as? String return cell }

and also check for numberOfRowsInSection function.

Nothing will be changed. – Pooja Srivastava Sep 26 '17 at 10:25
Then check if tableview reload data is getting called by using breakpoints inside your tableview functions – Anand Yadav Sep 26 '17 at 10:27

Try this

  func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return [self.array_RadioList].count;
}
