如何使用swift更改文件扩展名？

import Foundation

func changeFileExtension(filePath: String, newExtension: String) {
    let fileURL = URL(fileURLWithPath: filePath)
    let newFileURL = fileURL.deletingPathExtension().appendingPathExtension(newExtension)
    
    do {
        try FileManager.default.moveItem(at: fileURL, to: newFileURL)
        print("文件扩展名已更改为\(newExtension)")
    } catch {
        print("文件扩展名更改失败：\(error)")
    }
}

// 示例用法
let filePath = "/path/to/file.txt"
let newExtension = "jpg"
changeFileExtension(filePath: filePath, newExtension: newExtension)
