I have looked for this snippet all over the internet. Thank you

@polamgh did you ever figure it out?

@polamgh I encountered with the same issue. Xcode 8 swift 3. Did you figure it out?

@polamgh @Dengekiko Did anyone figure that out. Having same issue.

@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

The code is running well but when I lost the internet connection the code crash in the line "let allContactsData = try Data(contentsOf: url!)". Can someone help me? I am using swift 3

Thank You
