可编码:不符合协议“可解码"

本文介绍了可编码:不符合协议“可解码"的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

无法弄清楚为什么我的课程不符合Codable请注意，就我而言，我不需要实现 encoding 和 decode 的方法.

Not able to figure why my class does not conform to Codable Please not that in my case I do not need to implement the methods encode and decode.

public class LCLAdvantagePlusJackpotCache: Codable { public let token: String public let amount: NSNumber public let member: Bool public init(token: String, amount: NSNumber, member: Bool) { self.token = token self.amount = amount self.member = member } enum CodingKeys: String, CodingKey { case token, amount, member } }

推荐答案

这是因为NSNumber不可编码.不要使用Objective-C类型；使用Swift类型.(这是一条一般规则；它不限于可编码的情况.但这是为什么该规则是一个好规则的一个很好的例子！)

It's because NSNumber is not Codable. Do not use Objective-C types; use Swift types. (That's a general rule; it isn't confined to the Codable situation. But this is a good example of why the rule is a good one!)

将NSNumber更改为Int或Double(在代码中出现的两个地方)，一切都会好起来.

Change NSNumber to Int or Double (in both places where it occurs in your code) and all will be well.
