Using Alamofire calling JSONArray

I'm still beginner in iOS development. I'm using Swift 3, Alamofire 4 and SwiftyJson for my project. I try to fetch the data from JSON. JSON return in single array. Here is the return :

JSON :

[{
    "id": "1",
    "post_title": "Event_1",
    "post_content": "Taylor Swift",
    "start_date": "2016-11-23",
    "end_date": "2016-11-23",
    "post_date": "2016-11-18"
}, {
    "id": "2",
    "post_title": "Event_2",
    "post_content": "Nickelback",
    "start_date": "2016-11-15",
    "end_date": "2016-11-16",
    "post_date": "2016-11-15"
}, {
    "id": "3",
    "post_title": "Event_3",
    "post_content": "Nirvana",
    "start_date": "10.00pm on 22-02-2012",
    "end_date": "6.00am on 23-02-2012",
    "post_date": "2016-07-10"
}]

Swift :

var newsArray : [[String:Any]] = []

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return newsArray.count
}


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

    let currentNews = newsArray[indexPath.row]
    if let post_content = currentNews["post_content"] {
        cell.lbl_content.text = post_content as? String
    }

    return cell
}    


func getJSON(){

    Alamofire.request(BASE_URL).responseJSON {
        response in

        switch response.result {
        case .success(let value):
            let json = JSON(value)
            print(json)

            if let tempArray = json as? [[String: Any]] {
                self.newsArray = tempArray
                self.tableView.reloadData()
            }

        case .failure(let error):
            print(error)
        }
    }
}

Issue :

Looks like tempArray don't hold any value.

I try to implement the value in tableViewCell.

Any help is appreciated and many thanks.

Currently I'm not using Swift 3, Alamofire 4. I have found some solution in the below link. Please check, if you can any solution from this. Link: http://ashishkakkad.com/2015/10/how-to-use-alamofire-and-swiftyjson-with-swift/

Alamofire.request("http://api.androidhive.info/contacts/").responseJSON { (responseData) -> Void in
    if((responseData.result.value) != nil) {

         let swiftyJsonVar = JSON(responseData.result.value!)

        if let resData = swiftyJsonVar["contacts"].arrayObject {
            self.arrRes = resData as! [[String:AnyObject]]
        }
        if self.arrRes.count > 0 {
            self.tblJSON.reloadData()
        }
    }
}

    func getJSON(){

            print(json)

            if let tempArray = json as? NSArray {
                self.newsArray = tempArray
                print(tempArray)
                self.tableView.reloadData()
            }

        case .failure(let error):

You can try this code.

Alamofire.request(BASE_URL).responseJSON {
    response in

    switch response.result {
    case .success(let value):
        //to get JSON return value
        if let result = response.result.value {
            let JSON = result as! [[String: Any]]
            //then use guard to get the value your want

        }

case .failure(let error):
    print(error)
}

}

Please try Below

if let tempArray = json as? [[String: Any]] {
                self.newsArray = tempArray.mutableCopy()
                self.tableView.reloadData()
            }

Try this 

if let tempArray = json as? [[String: Any]] {
                self.newsArray = tempArray
                self.tableView.reloadData()
            }

Use json only don't json[]
