使用Swift更新Excel电子表格数据

我已经创建了一个Xcode项目，在项目文件夹中有一个电子表格，我正在使用xlsxreaderwriter连接到excel工作表

我的项目可以读取excel电子表格，并在程序运行时进行更新。我的问题是程序没有保存与新数据连接的excel电子表格。我的控制台显示它正在保存，但当我打开实际的电子表格文件时，它看起来像我创建的原始版本

下面是我创建的两个函数，用于设置单元格引用和保存我放入viewDidLoad中的数据

private func getExcelCells()  {

 let path: String = Bundle.main.path(forResource: "DatabaseV1", ofType: "xlsx")!

 //Open the spreadsheet, get get the first worksheet, and select cell B5
    let spreadsheet: BRAOfficeDocumentPackage = BRAOfficeDocumentPackage.open(path)
    let sheet: BRASheet = spreadsheet.workbook.sheets[0] as! BRASheet
    let worksheet: BRAWorksheet = spreadsheet.workbook.worksheets[0] as! BRAWorksheet

 // Creates variables that are type CellModel
    var cat1 = CellModel(categoryTitle: "Best DJ", firstCell: worksheet.cell(forCellReference: "B5"), secondCell: worksheet.cell(forCellReference: "B6"), thirdCell: worksheet.cell(forCellReference: "B7"), fourthCell: worksheet.cell(forCellReference: "B8"))
    let cat2 = CellModel(categoryTitle: "Best SGA", firstCell: worksheet.cell(forCellReference: "E5"), secondCell: worksheet.cell(forCellReference: "E6"), thirdCell: worksheet.cell(forCellReference: "E7"), fourthCell: worksheet.cell(forCellReference: "E8"))
    let cat3 = CellModel(categoryTitle: "Best Greek Organization", firstCell: worksheet.cell(forCellReference: "H5"), secondCell: worksheet.cell(forCellReference: "H6"), thirdCell: worksheet.cell(forCellReference: "H7"), fourthCell: worksheet.cell(forCellReference: "H8"))

// Add the variables created above to the array excelCells
    excelCells += [cat1, cat2, cat3]
   cat1.cellOne.setStringValue(nominees.optionA)
  let data =  worksheet.cell(forCellReference: "A5").stringValue()
    print(cat1.cellOne.stringValue())
    print(data)


    }

 private func saveExcelFile() {
   let path: String = Bundle.main.path(forResource: "DatabaseV1", ofType: "xlsx")!
        let spreadsheet: BRAOfficeDocumentPackage = BRAOfficeDocumentPackage.open(path)
        let sheet: BRASheet = spreadsheet.workbook.sheets[0] as! BRASheet
        let worksheet: BRAWorksheet = spreadsheet.workbook.worksheets[0] as! BRAWorksheet
        worksheet.save()
        spreadsheet.save()
    }

这是我从控制台中得到的结果，但当我从计算机文件中打开电子表格时，它没有更新

捆绑包位置是只读的。您需要将其保存在documents目录或其他地方。@LeoDabus您能指导我实现这个吗？
