字典转换model nil变成了"nil"

[MuRanJiangXia]

class PublishSubmitModel: Convertible {
var title = ""

var content = ""

required init() {}

}

// 测试
let dic = [
"title": "",
"content": nil
]

    let model = dic.kj.model(PublishSubmitModel.self)
    
    Logger.info("content: \(model.content)")

model中的content 变为“nil” 字符串了

在
func kj_modelValue(from jsonValue: Any?, _ property: Property) -> Any? {
方法中打印
Printing description of jsonValue:
▿ Optional

• some : nil

  func kj_modelValue(from jsonValue: Any?, _ property: Property) -> Any? {

  guard jsonValue != nil, property.dataType == String.self else {
      return jsonValue
  }
  
  if let newJson = jsonValue as? Bool {
      return newJson == true ? "1" : "0"
  }
  
  if let newJson = jsonValue as? NSNumber {
      return newJson
  }
  
  guard let newJson = jsonValue as? String else {
      // 处理 string nil ；Optional<Any> - some : nil
      return ""
  }
  return newJson
  

  }
  做了一下处理能规避一下 不知道还有好点的方法不
