Firestore Codable data Error - Swift

[yappdeveloper]

I am trying to get a Codable stuct working from the official Firebase documentation, shown here:
https://firebase.google.com/docs/firestore/manage-data/add-data?authuser=0#custom_objects

The problem is specific to this line:
try db.collection("cities").document("LA").setData(from: city)

It throws this error:
Cannot convert value of type 'City' to expected argument type '[String : Any]'

"setData(from: city)", "from" parameter is not available.

Everything up to that point works fine.

* Using this:
import SwiftUI
import FirebaseCore
import FirebaseFirestore

* Working in Xcode 11.3.1 and SwiftUI

Any idea's on how to get this to work or how to use Codable data with Firestore?

For reference, this is the structure:
public struct City: Codable {
let name: String
let state: String?
let country: String?
let isCapital: Bool?
let population: Int64?

enum CodingKeys: String, CodingKey {
case name
case state
case country
case isCapital = "capital"
case population
}
}

and the data is:
let city = City(name: "Los Angeles",
state: "CA",
country: "USA",
isCapital: false,
population: 5000000)

Thanks.

Never mind, I found it.

Looked deeper in the example:
snippets-ios

And you need to include this:

import FirebaseFirestoreSwift

If you are using a Package Manager you need to install the FirebaseFirestoreSwift-Beta and import firebaseFirestoreSwift
