在swift 2中使用PropertyListSerialization创建字典

import Foundation

// 创建一个字典
let dictionary: [String: Any] = [
    "name": "John Doe",
    "age": 30,
    "isStudent": false,
    "courses": ["Math", "Science"],
    "birthdate": Date()
]

do {
    // 将字典序列化为Data
    let plistData = try PropertyListSerialization.data(fromPropertyList: dictionary, format: .xml, options: 0)
    
    // 将Data保存到文件
    let fileURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first!.appendingPathComponent("data.plist")
    try plistData.write(to: fileURL)
    
    print("字典已成功保存到 \(fileURL)")
    
    // 从文件中读取Data
    let readData = try Data(contentsOf: fileURL)
    
    // 将Data反序列化为字典
    let readDictionary = try PropertyListSerialization.propertyList(from: readData, options: [], format: nil) as! [String: Any]
    
    print("从文件中读取的字典: \(readDictionary)")
} catch {
    print("发生错误: \(error)")
}
