如何在本地json文件iOS Swift中写入数据？

var jsonData = [String: Any]()

jsonData["username"] = "John Doe"

do {
    let data = try JSONSerialization.data(withJSONObject: jsonData, options: .prettyPrinted)
    // 在这里将data写入本地文件
} catch {
    print("Error converting JSON object to data: \(error)")
}

let fileManager = FileManager.default
let filePath = "path/to/your/file.json" // 替换为你的文件路径

if let fileUrl = URL(string: filePath) {
    do {
        try data.write(to: fileUrl)
        print("Data written to file successfully.")
    } catch {
        print("Error writing data to file: \(error)")
    }
}
