Getting error message: “Missing argument for parameter ‘structAttributeName’ in call” Swift

Question

I’m getting the following error message: “Missing argument for parameter ‘hours’ in call, where “hours” is an attribute of a struct, and I’m getting this error message in the line of code: “var selectedVenue = SelectedRestaurantDetailViewInfoNotUsingCodable()” in the code snippet further below.

There is a “Fix” button for this error message that says to add in the argument, and have the parameter be assigned to a different struct’s name which is the data type of “hours” in the first struct mentioned. The text just to the left of this “Fix” button: “Insert ', hours: <#OpenHoursForDaysOfWeek#>’”.

I’ve tried this “Fix” button, except I took out the extra comma and space before "hours" in the suggested line of code from the "Fix" button, also the result was the same as when the space and comma I took out were there, as I tried both. In this line of code where the "Fix" button is used, the assignment for the parameter of “hours” is set to the data type that the struct attribute also called “hours” is set to in the file with these structs, however I get the error message: “Cannot convert value of type 'OpenHoursForDaysOfWeek.Type' to expected argument type ‘OpenHoursForDaysOfWeek’" when I do this, where “OpenHoursForDaysOfWeek” is the data type that the “hours” attribute is set to, and which is a struct itself.

I’ve included the file that I’m receiving this “Missing argument for parameter ‘hours’ in call” in the below code snippet, and the file that has both of these struct definitions, where one struct has the “hours” attribute, and the other struct is the struct that is the data type for the just mentioned “hours” attribute.

Code:

You have to set the var hours: OpenHoursForDaysOfWeek? Optional.

Or if is not Optional, you have to declare the value when you instantiate it

var selectedVenue = SelectedRestaurantDetailViewInfoNotUsingCodable(hours: OpenHoursForDaysOfWeek(mondayOpenHoursWithoutDay: "text", 
tuesdayOpenHoursWithoutDay: "text", 
wednesdayOpenHoursWithoutDay: "text", 
thursdayOpenHoursWithoutDay: "text", 
fridayOpenHoursWithoutDay: <"text", 
saturdayOpenHoursWithoutDay: "text", 
sundayOpenHoursWithoutDay: "text", 
numberOfOpenHoursTimeRangesAsStringTypeOfTableViewCellToUse: "text"))
