Having trouble decoding JSON file in swift - json

Question

I am trying to decode a JSON format from CalorieNinja API but it appears that the equals signs in their jsons are throwing my code off. Here is my code for decoding the JSON file:
let dataTask = session.dataTask(with: request) { (data, response, error) in
//check errors
if error == nil && data != nil {
let decoder = JSONDecoder()
do{
let result = try decoder.decode(Result.self, from: data!)
print(result)
}catch{
print("there was an error")
print(error)
}
}
}
Here are my structs:
struct FoodItem: Codable {
var name: String?
var calories: String?
}
struct Result: Codable {
var items: [FoodItem]?
}
Here is the JSON format that gets returned from CalorieNinjas(this is just an example this is not the output of my code):
{
items = (
{
calories = "18.2";
"carbohydrates_total_g" = "3.9";
"cholesterol_mg" = 0;
"fat_saturated_g" = 0;
"fat_total_g" = "0.2";
"fiber_g" = "1.2";
name = tomato;
"potassium_mg" = 23;
"protein_g" = "0.9";
"serving_size_g" = 100;
"sodium_mg" = 4;
"sugar_g" = "2.6";
}
);
}
And lastly here is the error if it helps at all:
typeMismatch(Swift.String, Swift.DecodingError.Context(codingPath: [CodingKeys(stringValue: "items", intValue: nil), _JSONKey(stringValue: "Index 0", intValue: 0), CodingKeys(stringValue: "calories", intValue: nil)], debugDescription: "Expected to decode String but found a number instead.", underlyingError: nil))

You can check CalorieNinja API again. I think the calories field should be Double? due to their document.
