encodeEncodable(_:forKey:)

Encodes a given value and associates it with a key.

Declaration

@nonobjc func encodeEncodable<T>(_ value: T, forKey key: String) throws where T : Encodable

Parameters

  • value:

    The value to encode.

  • key:

    The key with which to associate the encoded value.

Discussion

If there’s a problem encoding the value you supply, this method throws an error based on the type of problem:

  • The value fails to encode, or contains a nested value that fails to encode—this method throws the corresponding error.

  • The value can’t be encoded as a property list—this method throws the EncodingError.invalidValue(_:_:) error.
