Load data from JSON in picker view

Question

I get data from a server and I have the following JSON:

(
    {
        id = 1;
        status = 1;
        title = "jimmy";
    },
        {
        id = 2;
        status = 1;
        title = "arnold";
    },
        {
        id = 3;
        status = 1;
        title = "mike";
    }
)

I want to load the title of this JSON in a picker view and when I select one of them, the id of the selected row is set in the myID variable. I wrote the below code but the picker view doesn't show anything:

var dictionary = [[String : AnyObject]]()

override func viewDidLoad() {
    super.viewDidLoad()

    pickerDep.delegate = self
    pickerDep.dataSource = self

    var Token=FuncClass.ReadData(_file: "fileToken.txt")
    let url=Property._URL+"getTicketDepartment"
    let parameters = [
        "token": Token
    ]

    Alamofire.request(url, method: .post, parameters: parameters, encoding: URLEncoding.httpBody).responseJSON { response in
        if let data = response.data {
            let json = String(data: data, encoding: String.Encoding.nonLossyASCII)

            let result=response.result
            self.dictionary = (result.value as? [Dictionary<String,AnyObject>])!
        }
    }
}

func numberOfComponents(in pickerView: UIPickerView) -> Int {
    return 1
}

func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
    return dictionary.count
}

func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
    return dictionary[row]["title"] as! String
}

What should I do?

You need to reload the picker view after the data is loaded from Alamofire:

Alamofire.request(url, method: .post, parameters: parameters, encoding: URLEncoding.httpBody).responseJSON { response in
    if let data = response.data {
        let json = String(data: data, encoding: String.Encoding.nonLossyASCII)

        let result=response.result
        if let array = result.value as? [Dictionary<String,AnyObject>] {
            self.dictionary = array
            pickerDep.reloadAllComponents()
        }
    }
}

BTW - why is your property named dictionary when it contains an array of data?
