DecodeFailable provides a custom Decodable collection that decoding for individual elements can fail silently for.
Thus, malformed or unknown elements in a JSON array won't result in a failure of the entire decoding.
It also makes it easy to log or add custom handling of decoding errors for those elements.
To run the example project, clone the repo, and run pod install from the Example directory first.

DecodeFailable is available through CocoaPods. To install it, simply add the following line to your Podfile:
pod 'DecodeFailable'If you prefer not to use CocoaPods, you can integrate DecodeFailable into your project manually.
Using DecodeFailable is very simple. All you need to implement is init(from decoder: Decoder) and use DecodeFailableArray for your array decoding.
import DecodeFailable
struct GetPeopleResponse: Codable {
private enum CodingKeys: String, CodingKey {
case people
}
let people: [Person]
public init(from decoder: Decoder) throws {
let container = try decoder.container(keyedBy: CodingKeys.self)
self.people = try container.decode(DecodeFailableArray<Person>.self, forKey: .people).elements
}
}
struct Person: Codable {
let id: String
let firstName: String
let lastName: String
