Add this to any Struct if you want a string of all the optional values that actually have defined content.

OptionalChildrenIntrospection.swift

    var whatDoIHave:String {
        let mirror = Mirror(reflecting: self)
        var itemsToDisplay:[String] = []
        
        for child in mirror.children  {
            //print("key: \(child.label), value: \(child.value)")
            if child.value is ExpressibleByNilLiteral  {
                let typeDescription = object_getClass(child.value)?.description() ?? ""
                if !typeDescription.contains("Null") && !typeDescription.contains("Empty") {
                    itemsToDisplay.append(child.label ?? "no_key")
                }
            }

        }
        
        let returnString = itemsToDisplay.count > 0 ? "Optionals Available: \(itemsToDisplay.joined(separator: ", "))" : ""
        return returnString
    }
