    }
]

I tried this

class DashboardProduct: NSObject {

    class dashProductBook : NSObject {

        static var products : [Product]!
        //MARK: Init
        @discardableResult init(dictionary: [String:Any]){

            dashProductBook.products = [Product]()
            if let dashProductArray = dictionary["products"] as? [[String:Any]]{
                for dic in dashProductArray{
                    let value = Product(dictionary: dic)
                    dashProductBook.products.append(value)
                }
            }

        }

        //MARK: Delete
        static func deleteFromModel()
        {
            products = nil

        }

        //MARK: Return data
        static func toDictionary() -> [String:Any]
        {
            var dictionary = [String:Any]()
            if products != nil{
                var dictionaryElements = [[String:Any]]()
                for productElement in products {
                    dictionaryElements.append(productElement.toDictionary())
                }
                dictionary["products"] = dictionaryElements
            }
            return dictionary
        }
    }

    class Product : NSObject{


        var items : [Items]!

        init(dictionary: [String:Any]) {

            items = [Items]()
            if let regionArray = dictionary["items"] as? [[String:Any]]{
                for dic in regionArray{
                    let value = Items(dictionary: dic)
                    items.append(value)
                }
            }

        }

        func toDictionary() -> [String:Any]
        {
            var dictionary = [String:Any]()

            if items != nil{
                var dictionaryElements = [[String:Any]]()
                for itemElement in items {
                    dictionaryElements.append(itemElement.toDictionary())
                }
                dictionary["items"] = dictionaryElements
            }

            return dictionary
        }
    }


    class Items : NSObject{

        var custom_Attr : [Custom_Attribute]!


        init(dictionary: [String:Any]) {

            custom_Attr = [Custom_Attribute]()
            if let custom_attributesArray = dictionary["custom_attributes"] as? [[String:Any]]{
                for dic in custom_attributesArray{
                    let value = Custom_Attribute(dictionary: dic)
                    custom_Attr.append(value)
                }
            }

        }

        func toDictionary() -> [String:Any]
        {
            var dictionary = [String:Any]()

            if custom_Attr != nil{
                var dictionaryElements = [[String:Any]]()
                for customElement in custom_Attr {
                    dictionaryElements.append(customElement.toDictionary())
                }
                dictionary["custom_attributes"] = dictionaryElements
            }

            return dictionary
        }
    }


    class Custom_Attribute : NSObject{

        var key: String?
        var value: String?

        init(dictionary: [String: Any]) {
            self.key = dictionary["key"] as? String
            self.value = dictionary["value"] as? String
        }

        func toDictionary() -> [String:Any]
        {
            var dictionary = [String:Any]()
            if key != nil{
                dictionary["attribute_code"] = key
            }
            if value != nil{
                dictionary["value"] = value
            }
            return dictionary
        }
    }
}

but its giving me error that "Cannot convert value of type 'NSArray' to type '[String: Any]' in coercion"

Here is an easy solution using ObjectMapper Library, You can refer this class

// Using ObjectMapper Library

import ObjectMapper
class jsonModel : Mappable {
var id = 0
var products: productsDataModel?
required init?(map: Map) {
    //
}
func mapping(map: Map) {
     id <- map["id"]
     products <- map["products"]
}  } class productsDataModel: Mappable {

var items : [itemsDataModel]?

required init?(map: Map) {
    //
}

func mapping(map: Map) {
    items <- map["items"]
}}class itemsDataModel: Mappable {

var status = 0
var custom_attributes = [custom_attributesDataModel]?

required init?(map: Map) {
    //
}

func mapping(map: Map) {
    status <- map["status"]
    custom_attributes <- map["custom_attributes"]
}}class custom_attributesDataModel: Mappable {

var attribute_code = ""
var value = ""

required init?(map: Map) {
    //
}

func mapping(map: Map) {
    attribute_code <- map["attribute_code"]
    value <- map["value"]
}}
