when i click a button in the navigation view controller , the view changes but only once the rest of the time it repeats

class ColorPagesView: UIViewController { var ColorProviderNames : Colors? var Pages : ColorPagesView?

var Number = 1
@objc func GoNextPage() {
    //Pages?.PagesList[+1]
   Number = Number + 1

    switch Number {
    case 1 : Pages = ColorPagesView(ColorsChoose: .Red)
    case 2: Pages = ColorPagesView(ColorsChoose: .Blue)
        case 3 : Pages = ColorPagesView(ColorsChoose: .Green)
        case 4 : Pages = ColorPagesView(ColorsChoose: .Yellow)

    default:
        Pages = ColorPagesView(ColorsChoose: .Yellow)
    }


    navigationController?.pushViewController(Pages!, animated: true)
}

//Right now the Pages is Nil , when i click the button , the view changes once and then just gets repeating the same , i want in a way where every time i click the button , the view gets updated , here the var 'Number' goes to 2 then never get 3

//i Programmed it that when the number gets added by 1 the navigation view also changes
