iterate JSON, swift

I am working on swift. The response that I get from the web server is different when i test it on Postman/ browser and mobile emulator.

Postman/browser response :

items: [
    {
    itemId: 500,
    name: "ABC"
    },
    {
    itemId: 500,
    name: "ABC"
    }
    ]

Response in iOS : 

 items: (
    {
    itemId: 500,
    name: "ABC"
    },
    {
    itemId: 500,
    name: "ABC"
    }
    )

I would like to know how to iterate through the array, but since the result is not an array on iOS I am not sure on how should I go about it. Also, I retrieve a result of around 25-30 items in the array. I have a some set of variables too, that are provided in the response after the array.

There is no problem with your response in ios when you print an array it will print with () brackets instead of [] brackets and dictionary will be print with {} braces.

As you say let items : [NSDictionary]! your items array contain dictionary then you can iterate it like this

for item in items {
    print(item["itemId"])
    print(item["name"])
}

You have an array of dictionaries. So, you can iterate like-

for itemDict in items {
    let itemId = itemDict["itemId"]
    println("Item ID: \(itemId)")

    let name = itemDict["name"]
    println("Item name: \(name)")
}

As others have said, your response in iOS is fine.

You can iterate over it simply with:

for item in items {

// do what you want with each item

}

It works fine in a Playground:

let items = [["itemId": 500, "name" : "ABC"], [ "itemId": 500, "name": "ABC"]] as NSArray


for item in items {
    print(item as! NSDictionary) // prints each dictionary as expected
}
