Try this code :-

   struct fontSizeConstant{

        static let relativeFontConstant : CGFloat = 0.015
        static let bigFontConst : CGFloat = 0.050
        static let lessBigFontConst : CGFloat = 0.040
        static let mediumFontConst : CGFloat = 0.030
    }
userName.font = userName.font?.withSize(self.view.frame.height * fontSizeConstant.mediumFontConst)

            password.font = password.font?.withSize(self.view.frame.height * fontSizeConstant.mediumFontConst)

            loginButton.titleLabel?.font = loginButton.titleLabel?.font.withSize(self.view.frame.height * fontSizeConstant.lessBigFontConst)
