Type 'AllImage' does not conform to protocol 'Decodable'/ 'Encodable'

问题

  1. struct AllImage: Codable {
  2.     let mediaReferenceID: String?
  3.     let url: String?
  4.     let title: String?
  5.     let description: String?
  6.     let icon: String?
  7.     let tags: [TagInfo]?
  8.     let footerSection: FooterSection?
  10.     enum CodingKeys: String, CodingKey {
  11.         case mediaReferenceID = "media_reference_id"
  12.         case url, title, description, icon
  13.         case ctaInfo = "cta_info"
  14.         case footerSection = "footer_section"
  15.     }
  16. }
英文: 
  1. struct AllImage: Codable {
  2.     let mediaReferenceID: String?
  3.     let url: String?
  4.     let title: String?
  5.     let description: String?
  6.     let icon: String?
  7.     let tags: [TagInfo]?
  8.     let footerSection: FooterSection?
  10.     enum CodingKeys: String, CodingKey {
  11.         case mediaReferenceID = "media_reference_id"
  12.         case url, title, description, icon
  13.         case ctaInfo = "cta_info"
  14.         case footerSection = "footer_section"
  15.     }
  16. }

Here the TagInfo and FooterSection is Codable too with containing only string types.

Any solution to this problem?

CodingKeys应该反映出所有继承了Codable的属性，不能有额外的字段。所以你还应该添加标签并删除ctaInfo。

  1. struct AllImage: Codable {
  2.     let mediaReferenceID: String?
  3.     let url: String?
  4.     let title: String?
  5.     let description: String?
  6.     let icon: String?
  7.     let tags: [TagInfo]?
  8.     let footerSection: FooterSection?
  10.     enum CodingKeys: String, CodingKey {
  11.         case mediaReferenceID = "media_reference_id"
  12.         case url, title, description, icon
  13.         // Commented out this
  14.         // case ctaInfo = "cta_info"
  15.         // Add tags
  16.         case tags = "tags"
  17.         case footerSection = "footer_section"
  18.     }
  19. }
  21. struct TagInfo : Codable {
  22.     
  23. }
  25. struct FooterSection : Codable {
  26.     
  27. }
英文:

CodingKeys should reflect all properties of that type inherits Codable and cant have extra field. So you should also add tags and remove ctaInfo.

  1. struct AllImage: Codable {
  2.     let mediaReferenceID: String?
  3.     let url: String?
  4.     let title: String?
  5.     let description: String?
  6.     let icon: String?
  7.     let tags: [TagInfo]?
  8.     let footerSection: FooterSection?
  10.     enum CodingKeys: String, CodingKey {
  11.         case mediaReferenceID = "media_reference_id"
  12.         case url, title, description, icon
  13.         // Commented out this
  14.         // case ctaInfo = "cta_info"
  15.         // Add tags
  16.         case tags = "tags"
  17.         case footerSection = "footer_section"
  18.     }
  19. }
  22. struct TagInfo : Codable {
  23.     
  24. }
  26. struct FooterSection : Codable {
  27.     
  28. }
