struct CodingUserInfoKeyA user-defined key for providing context during encoding and decoding.
init() Initializes self with default strategies.
var allowsJSON5: Bool { get set }Set to true to allow parsing of JSON5. Defaults to false.
var assumesTopLevelDictionary: Bool { get set }Set to true to assume the data is a top level Dictionary (no surrounding “{ }” required). Defaults to false. Compatible with both JSON5 and non-JSON5 mode.
var dataDecodingStrategy: JSONDecoder.DataDecodingStrategy { get set }The strategy to use in decoding binary data. Defaults to .base64.
var dateDecodingStrategy: JSONDecoder.DateDecodingStrategy { get set }The strategy to use in decoding dates. Defaults to .deferredToDate.
var keyDecodingStrategy: JSONDecoder.KeyDecodingStrategy { get set }The strategy to use for decoding keys. Defaults to .useDefaultKeys.
var nonConformingFloatDecodingStrategy: JSONDecoder.NonConformingFloatDecodingStrategy { get set }The strategy to use in decoding non-conforming numbers. Defaults to .throw.
func decode<T>(_ type: T.Type, from data: Data) throws -> T where T : Decodable Decodes a top-level value of the given type from the given JSON representation.
func decode<T>(_ type: T.Type, from data: Data, configuration: T.DecodingConfiguration) throws -> T where T : DecodableWithConfiguration func decode<T, C>(_ type: T.Type, from data: Data, configuration: C.Type) throws -> T where T : DecodableWithConfiguration, C : DecodingConfigurationProviding, T.DecodingConfiguration == C.DecodingConfiguration enum DataDecodingStrategyThe strategy to use for decoding Data values.
enum DateDecodingStrategyThe strategy to use for decoding Date values.
enum KeyDecodingStrategyThe strategy to use for automatically changing the value of keys before decoding.
enum NonConformingFloatDecodingStrategyThe strategy to use for non-JSON-conforming floating-point values (IEEE 754 infinity and NaN).
