Swift Save JSON String in a Loop with NSUserDefaults

today i figured out how to create a for in method to get different json value.. but now i can't figure out how to save it to have maybe an Array in NSUserDefaults. This is a part of my code : 

 if let vehicles = jsonData["vehicles"] as? NSDictionary {
                let vehiclesKeys = vehicles.allKeys
                for key in vehiclesKeys {
                    let vehiclenodb = ((jsonData ["vehicles"] as! NSDictionary)["\(key)"]! as! NSDictionary)["vechicle_no"]! as! String
                    let modelnodb = ((jsonData ["vehicles"] as! NSDictionary)["\(key)"]! as! NSDictionary)["model_no"]! as! String
                    let variantdb = ((jsonData ["vehicles"] as! NSDictionary)["\(key)"]! as! NSDictionary)["variant"]! as! String
                    let colordb = ((jsonData ["vehicles"] as! NSDictionary)["\(key)"]! as! NSDictionary)["color"]! as! String
                    let datepurchasedb = ((jsonData ["vehicles"] as! NSDictionary)["\(key)"]! as! NSDictionary)["date_of_purchase"]! as! String
                    let insurancecompanynamedb = ((jsonData ["vehicles"] as! NSDictionary)["\(key)"]! as! NSDictionary)["insurance_company_name"]! as! String
                    let insuranceexpirydatedb = ((jsonData ["vehicles"] as! NSDictionary)["\(key)"]! as! NSDictionary)["insurance_expiry_date"]! as! String
                    let fueltypedb = ((jsonData ["vehicles"] as! NSDictionary)["\(key)"]! as! NSDictionary)["fuelType"]! as! String




                    var vehicleno:Void = save.setObject(vehiclenodb, forKey: "VehicleNumberSave")
                    var modelno:Void = save.setObject(modelnodb, forKey: "ModelNumberSave")
                    var variant:Void = save.setObject(variantdb, forKey: "VariantSave")
                    var color:Void = save.setObject(colordb, forKey: "ColorSave")
                    var datepurchase:Void = save.setObject(datepurchasedb, forKey: "DateofPurchaseSave")
                    var insurancecompanyname:Void = save.setObject(insurancecompanynamedb, forKey: "InsuranceCompanySave")
                    var insuranceexpirydate:Void = save.setObject(insuranceexpirydatedb, forKey: "InsuranceExpirySave")
                    var fueltype:Void = save.setObject(fueltypedb, forKey: "FuelTypeSave")

                    save.synchronize()




                }
            }

with this code the problem is that it save the last value, i need to save both value so like vehicleno will be like = [1vehicle,2vehicle] how can i do that?

You have to make mutable array above for loop for example 

var answersArray : [String]

 answersArray = ["veh1", "veh2", "veh3", "veh4", "veh5", "veh6", "veh7"]

var arrayno = [String]()
for value in answersArray {
     arrayno.append(value)
     println(arrayno)
}

so the last value will be 

[veh1, veh2, veh3, veh4, veh5, veh6, veh7]

and you can store whole array....

It will definitely save the last value because you are updating the same "Key" again and again.

The better option is to take empty dictionary add the objects to it.

Example:

var myDict: NSDictionary = NSDictionary()

When the one loop completes, add the object to dictionary like:

myDict.setValue("Vehicle1": [arrData])

In "arrData", you can save your vehicle details as

var arrData = NSMutableArray()
dict.addObject(vehicleno)

Hope this helps!
