kouworks

kouworks is a one-person iOS studio run by Kou. This site is where I write about the engineering behind the apps: Swift and SwiftUI, on-device machine learning, StoreKit 2, and the unglamorous parts of getting an app through review and out the door.

Posts are short and practical — the notes I wish I had found while building. Start with theblog, or read more about the studio and the apps on theabout page.

New posts are published to the RSS feed. Questions and corrections are welcome at contact@kou-works.jp.
