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

struct AllImage: Codable {
    let mediaReferenceID: String?
    let url: String?
    let title: String?
    let description: String?
    let icon: String?
    let tags: [TagInfo]?
    let footerSection: FooterSection?

    enum CodingKeys: String, CodingKey {
        case mediaReferenceID = "media_reference_id"
        case url, title, description, icon
        case ctaInfo = "cta_info"
        case footerSection = "footer_section"
    }
}

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

Any solution to this problem?

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

struct AllImage: Codable {
    let mediaReferenceID: String?
    let url: String?
    let title: String?
    let description: String?
    let icon: String?
    let tags: [TagInfo]?
    let footerSection: FooterSection?

    enum CodingKeys: String, CodingKey {
        case mediaReferenceID = "media_reference_id"
        case url, title, description, icon
        // Commented out this
        // case ctaInfo = "cta_info"
        // Add tags
        case tags = "tags"
        case footerSection = "footer_section"
    }
}


struct TagInfo : Codable {
    
}

struct FooterSection : Codable {
    
}
