    getData()
    let index = sender.tag

    print(fooBar)
    phone  = dic.valueForKey("mobile").objectAtIndex(index) as! String

    print(phone)
    //   fooBar.givenName = dic.valueForKey("name").objectAtIndex(indexPath.row) as! String
    let name : String = dic.valueForKey("name").objectAtIndex(index) as! String
    print(fooBar.givenName)
    let homePhone = CNLabeledValue(label: CNLabelHome,
                                   value: CNPhoneNumber(stringValue: phone))

    fooBar.setValue(name, forKey: "givenName")
    fooBar.setValue([homePhone], forKey: "phoneNumbers")
    //   fooBar.phoneNumbers = [homePhone]
    print(fooBar)
            fooBar.middleName = "A."
            fooBar.familyName = "Bar"
    //        fooBar.nickname = "Fooboo"


    if #available(iOS 9.0, *) {
        switch CNContactStore.authorizationStatusForEntityType(.Contacts){
        case .Authorized:
            createContact()
        case .NotDetermined:
            store.requestAccessForEntityType(.Contacts){succeeded, err in
                guard err == nil && succeeded else{
                    return
                }
                self.createContact()
            }
        default:
            print("Not handled")
            if let url = NSURL(string: "tel://\(phone)") {
