Swift Playgrounds iPad - parse from json Financial Modelling Prep API

Question

G’day I’m trying to pull financial data from the FMP API.

import SwiftUI
import PlaygroundSupport
import Foundation

let url = URL(string: "https://financialmodelingprep.com/api/v3/income-statement/AAPL?apikey=XXXX")

var request = URLRequest(url: url!)

request.addValue("application/json", forHTTPHeaderField: "Accept") //error flag
let task = URLSession.shared.dataTask(with: url!) { data, response, error in
    guard error == nil else {
        print(error!)
        return
    }
    guard let data = data else {
        print("Data is empty")
        return
    }
    
    let json = try! JSONSerialization.jsonObject(with: data, options: [])
    print(json)
}

task.resume() //error flag
PlaygroundPage.current.needsIndefiniteExecution = true //error flag

This is the code they suggest for swift, but I’m getting errors of “expressions are not allowed at the top level” when I attempt this in Playgrounds on iPad. Any idea what’s going wrong?

Appreciate any help. Cheers
