I'm new at Swift and that's why i need your help. So I have a function which should send request and return a value
func getAnswer() -> String? {
var answer: String?
guard let url = URL(string: "https://8ball.delegator.com/magic/JSON/_") else { return nil }
URLSession.shared.dataTask(with: url) { data, response, error in
guard let data = data, error == nil else {
return
}
guard let response = response as? HTTPURLResponse else { return }
guard response.statusCode == 200 else { return }
do {
let model = try JSONDecoder().decode(Answer.self, from: data)
DispatchQueue.main.async {
answer = model.magic.answer
}
} catch let error {
fatalError(error.localizedDescription)
}
}.resume()
return answer
}
but it always returns nil.
I suppose problem is here
DispatchQueue.main.async {
answer = model.magic.answer
}
How can I resolve it?
