How to display parsed JSON data in Swift? - ios

Question

After parsing JSON trough an API call i've had trouble converting the parsed JSON into the data that i want to display in my ViewController. I am able to print the JSON data in the console but i am not able to only get the value of "word: .." from the data i want to display. This is an example of a JSON object:
{
"metadata": {},
"results": [
{
"id": "eurhythmic",
"word": "eurhythmic"
}
]
}
The struct i'm using is the following:
// Struct RandomWords
struct StoreRandomWords: Codable {
let results: [Result]
}
struct Result: Codable {
let word: String
}
The code to fetch the data from the API:
func fetchRandomWord(completion: #escaping (StoreRandomWords?) -> Void) {
let language = "en"
let filters = "registers%3DRare%3Bdomains%3DArt?"
let limit = "limit=1"
let url = URL(string: "https://od-api.oxforddictionaries.com:443/api/v1/wordlist/\(language)/\(filters)\(limit)")!
var request = URLRequest(url: url)
request.addValue("application/json", forHTTPHeaderField: "Accept")
request.addValue(appId, forHTTPHeaderField: "app_id")
request.addValue(appKey, forHTTPHeaderField: "app_key")
let task = URLSession.shared.dataTask(with: request) { data, response, error in
if let data = data {
do {
let jsonData = try JSONDecoder().decode(StoreRandomWords.self, from: data)
print(jsonData)
} catch {
print(error)
}
} else {
print(error)
print(NSString.init(data: data!, encoding: String.Encoding.utf8.rawValue)!)
}
}
task.resume()
}
And the code from ViewController in which i want to load the "word":
// Do any additional setup after loading the view.
override func viewDidLoad() {
super.viewDidLoad()
// Fetch data for Daily Word.
ContextController.shared.fetchRandomWord( completion: { (storeRandomWord) in
if let storeRandomWord = storeRandomWord {
//
}
})
}
Which gives me this output in the console:
StoreRandomWords(results: [GetContext.Result(word: "eurhythmic")])
And my goal is to literally display the value word which is here "eurhythmic".
(I'm a beginner and not a native speaker of English so any feedback on how to improve the code or the question would be helpful and welcome to. )

Answer 1

You will have to loop the array or access the index science storeRandomWords.results is an array.
For example print the first result:
if let storeRandomWord = storeRandomWord {
print(storeRandomWord.results.first.word)
}
