Parsing data to the correct data-type

[t0chas]

Hi,

I came across this issue, when fetching data from a REST service a value that should be conformed as string value is being delivered without the quotes when the value is a number. Causing the mapping to parse and assign a long value to a string property.
The problem raises when assigning the string property to almost any UIKit object property.

{
  "id": 102,
  "challenge_id": 19,
  "start_timestamp": "2016-08-30 16:13:25",
  "end_timestamp": "2016-08-31 23:55:00",
  "match_date": "2016-09-01",
  "nfl_week": 4,
  "tie_question": "The most passing yards this week?",
  "tie_answer": "",
  "num_swipes": 20,
  "has_results": 0,
  "status_id": 1,
  "created_at": "2016-08-30 16:12:53",
  "updated_at": "2016-08-30 16:12:56",
  "total_startorsits": 20,
  "completed_startorsits": 0,
  "total_players": null,
  "challenge_image_url": "46996a9b8bd243ac94de9fc3e578d447.jpg",
  "banner_image_url": "ef8c56fe6ade4cdcb5866490dd0cccf7.jpg",
  "challenge_price_title": 333333,
  "sport_id": 1
}

Here "challenge_price_title": 333333, is the offending key/value.

The property is defined as NSString*

And here the debugger shows it has a value of type NSCFNumber

Would it be possible to enforce the correct data type is assigned to the properties?
