Swift PickerView does not show array elements - arrays

Question

My "picker2" pickerview does not show data from "modelArray" array. When I dup the array I have data in it. But no data shown in pickerview at all.
I did everything on mind and did my research how to do it. But no success.
Any help will be highly appreciated :)
import UIKit
class MakeViewController: UIViewController, UIPickerViewDataSource, UIPickerViewDelegate {
#IBOutlet weak var txt_make: UITextField!
#IBOutlet weak var txt_model: UITextField!
var makeArray = [String]()
var modelArray = [String]()
var picker = UIPickerView()
var picker2 = UIPickerView()
var numberOfRowsMake = 0
var numberOfRowsModel = 0
override func viewDidLoad() {
super.viewDidLoad()
picker.delegate = self
picker.dataSource = self
picker2.delegate = self
picker2.dataSource = self
txt_make.inputView = picker
txt_model.inputView = picker2
txt_make.clearButtonMode = .Always
txt_model.clearButtonMode = .Always
parseJSON2()
}
func parseJSON2() {
let path : String = NSBundle.mainBundle().pathForResource("json2", ofType: "json")! as String
let jsonDATA = NSData(contentsOfFile: path) as NSData!
numberOfRowsMake = readableJSON["Cars"].count
for var i = 0; i < numberOfRowsMake; ++i {
let make = readableJSON["Cars"][i]["Manufacturer"].stringValue
makeArray.append(make)
}
}
func parseJSON3() {
let path : String = NSBundle.mainBundle().pathForResource("json2", ofType: "json")! as String
let jsonDATA = NSData(contentsOfFile: path) as NSData!
numberOfRowsMake = readableJSON["Cars"].count
for var i = 0; i < numberOfRowsMake; ++i {
let make = readableJSON["Cars"][i]["Manufacturer"].stringValue
let model = readableJSON["Cars"][i]["Model"].stringValue
print(txt_make.text)
if make == txt_make.text {
modelArray.append(model)
}
}
dump(modelArray)
}
func numberOfComponentsInPickerView(pickerView: UIPickerView) -> Int {
return 1
}
func pickerView(pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
if pickerView == picker {
return numberOfRowsMake
}
if pickerView == picker2 {
return numberOfRowsModel
}
return 1
}
func pickerView(pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
if pickerView == picker {
txt_make.text = makeArray[row]
}
if pickerView == picker2 {
self.picker2.reloadAllComponents()
parseJSON3()
txt_model.text = modelArray[row]
}
}
func pickerView(pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
if pickerView == picker {
return makeArray[row]
}
if pickerView == picker2 {
return modelArray[row]
}
return ""
}
}
Here is the local JSON file.
{
"Cars" :
[{
"Manufacturer": "ABARTH1",
"Model": "500, 2012 onwards",
}, {
"Manufacturer": "ABARTH1",
"Model": "500, 2012 onwards",
}, {
"Manufacturer": "ABARTH1",
"Model": "500, 2012 onwards",
}, {
"Manufacturer": "ABARTH2",
"Model": "500, 2012 onwards",
}, {
"Manufacturer": "ABARTH2",
"Model": "500, 2012 onwards",
}, {
"Manufacturer": "ABARTH2",
"Model": "500, 2012 onwards",
}
]
}
