Filter json response in array of dictionary inside dictionary Swift iOS

I am getting a response of NSDictionary list of products as

 {
"products": {
    "title": "Chair",
    "regular_price": "2.22",
    "dimensions": {
        "width": "",
        "height": "",
        "length": ""
    },
    "attributes": [{
        "options": ["11\/30\/2016"],
        "name": "Arrival Date"
    }, {
        "options": ["Black"],
        "name": "Color"
    }],
    "categories": ["28"]
}

}.....

Using NSPredicate I could filter the products containing value "Chair" using

let namepredicate = NSPredicate(format: "title == Chair")
           self.filteredProducts = (self.product).filteredArrayUsingPredicate(namepredicate)

But How can I filter "Color", "Black" which inside the attributes and "Black" is inside another array(Swift)?

First of all, rename self.product to self.products. It's an array of multiple products, name it accordingly.

You can replace the existing NSPredicate mess with just:

self.filteredProducts = self.products.filter{ $0["title"] == "Chair" }

And you can filter by Color like so:

self.filteredProducts = self.products.filter{ product in
    return product["attributes"]?.contains{ attribute in
        return attribute["name"] == "Color" &&
               attribute["options"]?.contains("Black") ?? false
    } ?? false
}
