如何在iPhone sdk中创建Excel工作表和文件？

import libxlsxwriter

// 创建一个Excel工作簿
let workbook = Workbook()

// 创建一个工作表
let worksheet = workbook.addWorksheet("Sheet1")

// 添加标题行
let header = ["Name", "Age", "Gender"]
worksheet.writeRow(row: 0, col: 0, data: header)

// 添加数据行
let data = [
    ["Alice", 25, "Female"],
    ["Bob", 30, "Male"],
    ["Charlie", 22, "Male"]
]

for (index, item) in data.enumerated() {
    worksheet.writeRow(row: index + 1, col: 0, data: item)
}

// 设置文件路径
let documentsDirectory = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first!
let filePath = documentsDirectory.appendingPathComponent("example.xlsx")

// 保存工作簿为文件
workbook.close()
try? workbook.save(to: filePath)
