Swift’s memberwise initializer and the extension dance

Swift's automatically provided memberwise initializer is a powerful feature. However, when an explicit initializer is present, Swift omits its memberwise initializer:

struct Person: Decodable {
  let name: String

  enum CodingKeys: CodingKey {
    case name

Anti-hype LLM reading list

Goals: Add links that are reasonable and good explanations of how stuff works. No hype and no vendor content if possible. Practical first-hand accounts of models in prod eagerly sought.
