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
in xcode 8
in simulator is ok but when select the phone got this message 'Ambiguous use of subscript' at the line 'let aObject = arrJSON[index] as! [String : AnyObject]'
