Parse JSON in Objective-C from REST API

Question

I am facing an issue when trying to parse this sample JSON coming from a REST API using NSJSONSerialization.

I am using option NSJSONReadingallowfragment but it's not getting converted to JSON, it is still in NSString.

Error: "unrecognized selector sent to instance 0x7f9e53827600".

NSError *jsonError = nil;
NSArray *jsonArray = [NSJSONSerialization JSONObjectWithData: responseData options: NSJSONReadingMutableContainers error: &jsonError];

if (!jsonArray) {
  NSLog(@"Error parsing JSON: %@", e);
} else {
   for(NSDictionary *item in jsonArray) {
      NSLog(@"Item: %@", item);
   }
}
