How would I work with JSON that has no Key:Value pair in Swift using URLSession? – Ios swift

I am trying to access each title in a returned json. This is the JSON

[
    "Hyouka",
    "Youjo Senki",
    "Bungou Stray Dogs 2nd Season",
    "Fullmetal Alchemist: Brotherhood",
    "Tokyo Ghoul √A",
    "Mahouka Koukou no Rettousei",
    "Boku wa Tomodachi ga Sukunai NEXT",
    "Joker Game",
    "Avatar: The Last Airbender",
    "Charlotte"
]

It’s just a bunch of values and no key for me to construct my model object. This is how I would plan to do it

struct AllNames {
    
    let name: String   
}

But there’s no key name for me to access. How would you go about accessing this data to print each name to the console in Swift?

    Your json is an array of strings , so no model is here and you only need

    do {
    let arr = try JSONDecoder().decode([String].self, from: jsonData)
    print(arr)
 }
 catch {
    print(error)
 }

    Convert JSON string to array:

        func getArrayFromJSONString(jsonStr: String) -> Array<Any> {
        
        let jsonData: Data = jsonStr.data(using: .utf8)!
     
        let arr = try? JSONSerialization.jsonObject(with: jsonData, options: .mutableContainers)
        
        if arr != nil {
            return arr as! Array<Any>
        }
        
        return []
    }

    Test case:

        let jsonStr = """
    [
        "Hyouka",
        "Youjo Senki",
        "Bungou Stray Dogs 2nd Season",
        "Fullmetal Alchemist: Brotherhood",
        "Tokyo Ghoul √A",
        "Mahouka Koukou no Rettousei",
        "Boku wa Tomodachi ga Sukunai NEXT",
        "Joker Game",
        "Avatar: The Last Airbender",
        "Charlotte"
    ]
    """
    
    let arr = getArrayFromJSONString(jsonStr: jsonStr)
    
    print(arr)

    Print log:

    [Hyouka, Youjo Senki, Bungou Stray Dogs 2nd Season, Fullmetal Alchemist: Brotherhood, Tokyo Ghoul √A, Mahouka Koukou no Rettousei, Boku wa Tomodachi ga Sukunai NEXT, Joker Game, Avatar: The Last Airbender, Charlotte]
