I made a simple sudoku game in swift for IOS the problem is that I made that the generated number will be bold so the user will see that he cant change them and that they are the generated number. To that I made a class that will hold the number and a boolean variable that will represent if the number is generated or set by the user. The problem is that it wont work now and the sudoku is neither generated to the user can put a number in the boxes. Here is code for the sudoku since they are at two different files.
import SwiftUI
// Enumeration that is used to display the result if checking a sudoku.
public enum ResultsOfCheckedSudoku {
case notChecked
case notFilled
case correct
case incorrect
}
// Class that is used to create a custom numbers for the UI.
class Number {
// Variable that will hold the number.
private var num: String
// Variable that is used to determine if the number was generated.
private var isGenerated: Bool
// Simple initialiser.
init(num: String, isGenerated: Bool) {
self.num = num
self.isGenerated = isGenerated
}
// Getters and setters.
public func getNum() -> String {
return num
}
public func setNum(num: String) {
self.num = num
}
public func getIsGenerated() -> Bool {
return isGenerated
}
public func setIsGenerated(isGenerated: Bool) -> Void {
self.isGenerated = isGenerated
}
}

Thanks for the help in advance.
I tried to debug it using the build in Xcode debugger and print the values, but none of those work.
