@maninipoornam : Just small changes in above code and it's working on phone.

let allContacts = try JSONSerialization.jsonObject(with: allContactsData, options: JSONSerialization.ReadingOptions.allowFragments) as! [String : NSArray]
            if let arrJSON = allContacts["contacts"] {
                for index in 0...arrJSON.count-1 {
                    
                    let aObject = arrJSON[index] as! [String: Any]
                    
                    names.append(aObject["name"] as! String)
                    contacts.append(aObject["email"] as! String)
                }
            }

let allContactsData = try Data(contentsOf: self.url!)
let allContacts = try JSONSerialization.jsonObject(with: allContactsData, options: JSONSerialization.ReadingOptions.allowFragments) as! [String : AnyObject]
if let arrJSON = allContacts["data"] as! [String]?{
for index in 0...arrJSON.count-1 {

                let aObject = arrJSON[index] as! String
