Create JSON array and JSON Object in swift

I want do this JSON in Swift. But i cant do this....


{
"room": "Platinum",
"products": [{
"name": "Agua",
"quantity": 2
},
{
"name":"Cafe",
"quantity": 4
}],
"observation": "",
"date": "2016-08-15 12:00:00"
}


My swift code returns this:



{
date = "2016-08-25 18:16:28 +0000";
observation = "";
products = (
{
name = cafe;
quantity = 1;
}
);
room = Platinium;



This is my code....



let para:NSMutableDictionary = NSMutableDictionary()
let prod: NSMutableDictionary = NSMutableDictionary()

para.setValue(String(receivedString), forKey: "room")
para.setValue(observationString, forKey: "observation")
para.setValue(stringDate, forKey: "date")

for product in products{
prod.setValue(product.name, forKey: "name")
prod.setValue(product.quantity, forKey: "quantity")
para.setObject([prod], forKey: "products")


}


This is my input:



{
name = coffe;
quantity = 2;
}
{
name = cappuccino;
quantity = 1;
}



This is output



{
date = "2016-08-25 18:52:30 +0000";
observation = "";
products = (
{
name = cappuccino;
quantity = 1;
}
);
room = Platinium;
}



I created a request to send the two products, but the code prints only the last product.... I need a little help with this...

Thank you.

Answer

You need to move let prod: NSMutableDictionary = NSMutableDictionary() inside the for loop and move para.setObject([prod], forKey: "products") after the for loop, but you also need to change so you create and add each prod to an array in the loop and then add that array to para after the loop.

Your current code keeps replacing things rather than adding so at the end you only have the last one.
