您可以使用 convertToDictionary() 和 convertToArrayOfDictionary()

extension String {


    func convertToArrayOfDictionary() -> [[String: Any]]? {
        if let data = data(using: .utf8) {
            return try? JSONSerialization.jsonObject(with: data, options: []) as? [[String: Any]]
        }
        return nil
    }

    func convertToDictionary() -> [String: Any]? {
        if let data = data(using: .utf8) {
            return try? JSONSerialization.jsonObject(with: data, options: []) as? [String: Any]
        }
        return nil
    }
}
