Decoder

public extension Decoder

  • Decode a singular value from the underlying data.

    Declaration

    Swift

    func decodeSingleValue<T>(as type: T.Type = T.self) throws -> T where T : Decodable

  • Decode a value for a given key, specified as a string.

    Declaration

    Swift

    func decode<T>(_ key: String, as type: T.Type = T.self) throws -> T where T : Decodable

  • Decode a value for a given key, specified as a CodingKey.

    Declaration

    Swift

    func decode<T, K>(_ key: K, as type: T.Type = T.self) throws -> T where T : Decodable, K : CodingKey

  • Decode an optional value for a given key, specified as a string. Throws an error if the specified key exists but is not able to be decoded as the inferred type.

    Declaration

    Swift

    func decodeIfPresent<T>(_ key: String, as type: T.Type = T.self) throws -> T? where T : Decodable

  • Decode an optional value for a given key, specified as a CodingKey. Throws an error if the specified key exists but is not able to be decoded as the inferred type.

    Declaration

    Swift

    func decodeIfPresent<T: Decodable, K: CodingKey>(
    _ key: K,
    as type: T.Type = T.self
) throws -> T?

  • Decode a date from a string for a given key (specified as a string), using a specific formatter. To decode a date using the decoder’s default settings, simply decode it like any other value instead of using this method.

    Declaration

    Swift

    func decode<F>(_ key: String, using formatter: F) throws -> Date where F : AnyDateFormatter

  • Decode a date from a string for a given key (specified as a CodingKey), using a specific formatter. To decode a date using the decoder’s default settings, simply decode it like any other value instead of using this method.

    Declaration

    Swift

    func decode<K, F>(_ key: K, using formatter: F) throws -> Date where K : CodingKey, F : AnyDateFormatter
