如何遍历从JSON字符串解析的JSValue

import SwiftyJSON

let jsonString = """
{
  "name": "John",
  "age": 30,
  "isStudent": true,
  "hobbies": ["reading", "swimming", "coding"],
  "address": {
    "street": "123 Main St",
    "city": "New York",
    "country": "USA"
  }
}
"""

if let data = jsonString.data(using: .utf8) {
    do {
        let json = try JSON(data: data)
        traverseJSON(json)
    } catch {
        print("Failed to parse JSON: \(error)")
    }
}

func traverseJSON(_ json: JSON) {
    for (key, value) in json {
        print("Key: \(key)")
        
        if let subJSON = value.array {
            // Handle array
            for subValue in subJSON {
                traverseJSON(subValue)
            }
        } else if let subJSON = value.dictionary {
            // Handle dictionary
            traverseJSON(subJSON)
        } else {
            // Handle other types
            print("Value: \(value)")
        }
    }
}
