I am trying to get stock data from the website with an API Request. In that example I want to extract the symbol of a stock, by pressing the button. The code has no errors itself, but I does not display the API request and providing the symbol in that case `AAPL` to the simulator. Do you have any idea of what am I doing wrong?

```swift
struct Helper: View {
    @State private var quoteData: QuoteData?
    var body: some View {
        HStack {
            Spacer()

            VStack(alignment: .leading) {
                Text(quoteData?.symbol ?? ".")

                Button(action: loadData) {
                    Text("Press here")
                }

            }
        }
        .onAppear(perform: loadData)
    }

    private func loadData() {
        guard let url = URL(string: "https://financialmodelingprep.com/api/v3/quote/AAPL?apikey=836129f3de1b99ff975e910a4541254d") else {
            return
        }
        URLSession.shared.dataTask(with: url) { data, response, error in guard let data = data else { return }
            if let decodedData = try?JSONDecoder().decode(QuoteData.self, from: data) {
                DispatchQueue.main.async {
                    self.quoteData = decodedData
                }
            }
        }.resume()
    }

}

Here i just try to take the symbol from the stock which is of type string. The API adress does not have an id.

struct QuoteData: Decodable {
    var symbol: String?
}

struct Helper_Previews: PreviewProvider {
    static var previews: some View {
        Helper()
    }
}

```
