How do you define an enum value in the dataobject?

I have a table with a column named “gender” with possible values of “F”, “M”, “U” as strings.
How can I map this to an enum in my data object in Swift?

enum Gender: String {
 
 case Female = "F"
 case Male = "M"
 case Unisex = "U"
 
 init(_ value: String) {
 self.init(rawValue: value)!
 }
}

What I want is something like:

enum Gender: String {
 
 case Female = "F"
 case Male = "M"
 case Unisex = "U"
 
 init(_ value: String) {
 self.init(rawValue: value)!
 }


}

Thanks

You cannot use enum as a property of data model class.
