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 isn’t encodable as a JSON array or JSON object—this method throws the EncodingError.invalidValue(_:_:) error.
The value contains an exceptional floating-point number (such as infinity or nan) and you’re using the default JSONEncoder.NonConformingFloatEncodingStrategy — this method throws the EncodingError.invalidValue(_:_:) error.
