GraphQL iOS Swift Custom Scalar

I'm using GraphQL latest version 1.9.3
They have removed option of passThroughCustomScalar

Currently response is coming in dictionary form and schema.graphql has generated as below

public typealias JSON = String

I've tried below code to convert string to dictionary

extension JSON: JSONDecodable, JSONEncodable {
    public init(jsonValue value: JSONValue) throws {
        switch value {
        case let string as String:
            self = string
        case let int as Int:
            self = String(int)
        case let dictionary as [String: Any]:
            guard let data = try? JSONSerialization.data(withJSONObject: dictionary, options: []) else { fallthrough }
            guard let serializedJson = String(data: data, encoding: .utf8) else { fallthrough }
            self = serializedJson
        default:
            throw JSONDecodingError.couldNotConvert(value: value, to: String.self)
        }
    }
    
    public var jsonValue: JSONValue {
        return self
    }
}

Still I'm getting error of jsondecoding

ApolloAPI.JSONDecodingError.couldNotConvert(value: AnyHashable
 to: Swift.String))

Please help me
