Can't download file from Firebase Storage swift 4.2 - swift

Question

I changed the permissions on the Firebase console and set to allow all users access without the need for an authentication.
I have the following code:
AppDelegate.swift
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool
{
FirebaseApp.configure()
Utils.initApp()
return true
}
Utils.swift
import Foundation
import Firebase
class Utils
{
static var inventoryJsonString = "Inventory/Inventory.json"
static var oneMB : Int64 = 1024 * 1024
static func initApp()
{
getJsonDate(inventoryJsonString)
}
static func getJsonData(filePath: String)
{
let storageRef = Storage.storage().reference()
let jsonRef = storageRef.child("Inventory")
jsonRef.getData(maxSize: self.oneMB)
{
extractedData, error in
print("a")
if let error = error{
print("b")
}
else
{
print("c")
}
}
}
I'm calling that function but nothing happnes - I don't get an error, yet I'm not getting the url (also tried with getData and got nothing). I tripple checked the path in filePath and it's correct.
What am I missing here?

I assume you're trying to read the actual json file, not all the files within the Inventory path
Here's your code with notes on how to fix:
class Utils
{
static var inventoryJsonString = "Inventory/Inventory.json" //NOT USED!
static var oneMB : Int64 = 1024 * 1024
static func initApp() {
getJsonDate(inventoryJsonString)
}
static func getJsonData(filePath: String) { //filePath is NOT USED!
let storageRef = Storage.storage().reference()
**this is a PATH to the enclosing directory only and not the JSON file**
let enclosingPathRef = storageRef.child("Inventory")
**add this to make it work**
let actualFileRef = enclosingPathRef.child("Inventory.json")
actualFileRef.getData(maxSize: self.oneMB) { extractedData, error in
if let error = error{
print("an error occurred: \(error.localizedDescription")
} else {
print("success!")
}
}
}
}
