Apple will reject your app if people can create an account but have no way to delete it inside the app. AI tools usually build the sign up screen & skip this one, so it's worth checking before you submit. #AppStore #AppStoreReview #iOSDevelopment #VibeCoding #Startups #Founders

Hiring one good engineer can take months, and while you wait, the roadmap keeps slipping. We made a 2-minute video that explains what we do at Penguin in plain words. 🧵 #SoftwareDevelopment #Startups #Engineering

At last: a unified home for Swift documentation, pulling together the language reference, core libraries and tooling, and platform specifics into a single central home, no matter what you're building! Check it out and give us feedback: docs.swift.org

It worked perfectly in development. Every screen, every button, every time. Then it went live, and one specific phone on one specific network crashed on the signup screen. #SoftwareTesting #QA #MobileDevelopment #ProductEngineering #Startups

Someone once asked us to "just make it like this app, but for us." That sentence took forty decisions to actually build, and the client never saw a single one of them. We broke down what actually happens between the idea and the launch, the part nobody puts in the pitch.
