如何在swift 5中将.txt文件json读入字典

import Foundation

func readJSONFromFile(fileName: String) -> [String: Any]? {
    if let filePath = Bundle.main.path(forResource: fileName, ofType: "txt") {
        do {
            let fileUrl = URL(fileURLWithPath: filePath)
            let data = try Data(contentsOf: fileUrl)
            let json = try JSONSerialization.jsonObject(with: data, options: [])
            if let dictionary = json as? [String: Any] {
                return dictionary
            }
        } catch {
            print("Error reading JSON file: \(error)")
        }
    }
    return nil
}

if let jsonDictionary = readJSONFromFile(fileName: "example") {
    // 在这里可以使用jsonDictionary进行进一步的处理
    print(jsonDictionary)
} else {
    print("Failed to read JSON file.")
}
