json post nested objects in swift using alamofire

Question

i want to post nested json objects in API using Alamofire my objects structere is like this

["example" :
 {
 "fname":"john",
 "lnamed":"Doe"
 },{
 "fname":"john",
 "lname":"Doe"
 },
.
.
.
]

my problem is when i'm making array it becomes like ["example":[["fname":"john","lname":"Doe"],["fname":"john","lname":"Doe"]]] so their is one square bracket extra because of the array. below is my codes

var exampleObj = [String:AnyObject]()

var examplesArray  = [exampleObj]

    for example in examples
    {

        exampleObj = ["fname":example[fname] as AnyObject, "lname":example["lname"] as AnyObject]

        examplesArray.append(exampleObj)
    }



        let parameters = ["example": examplesArray] 

Answer 1

after while i discovered my problem was with the Alamofire request i forgot to add the encoding parameter and the solution is

Alamofire.request("https://httpbin.org/post", parameters: parameters, encoding: URLEncoding.httpBody)
