Shopify iOS SDK error: Value of type 'Storefront.ShopQuery' has no member 'currencyCode'

Question

I'm getting started with Shopify's iOS sdk and in following the official readme on GitHub, I keep getting an error that I can't get rid of. I've followed the setup and pasted the example code line for line and I get This error no matter what project I try to use it on (full code in attachments)

Value of type 'Storefront.ShopQuery' has no member 'currencyCode'

How can I fix this error?

import Buy
import Pay

class shopify {
    let client = Graph.Client(shopDomain: "-", apiKey: "-")
    
    func example() {
        let query = Storefront.buildQuery { $0
            .shop { $0
                .name()
                .currencyCode()
                .refundPolicy { $0
                    .title()
                    .url()
                }
            }
        }
        
        let task = client.queryGraphWith(query) { response, error in
            let name         = response?.shop.name
            let currencyCode = response?.shop.currencyCode
            let moneyFormat  = response?.shop.moneyFormat
        }
        task.resume()
    }
}

You find this in paymentSetting, I guess

let query = Storefront.buildQuery { $0
        .shop { $0
            .name()
            .paymentSettings { $0
                .currencyCode()
            }
        }
    }
