Keep Writing, Keep Coding

上一次认真思考“如何学习”这件事，还是在看 Scott 那本书的时候。他一年之内自学完了四年制大学的 CS 课程。最近我又开始有点迷茫。快四十了，后端不算真正精通，iOS 技能也荒废了，语言也没学好。这些问题叠在一起，让我压力很大。结果又开始玩 Dota 2 来逃避。

早上躺在床上挣扎起床, 拿起手机刷完邮件, 和工作IM之后忍不住打开了X. 看到一个tweet https://x.com/Lakr233/status/1972677999729512858. 看了下, 随口说出了答案是200. 但是 @Lakr233 说他这个问题另有深意. 所以赶紧起床研究问题.

Sometimes, you have to explore different paths to find where you truly belong. For a developer, that path is often paved with different languages, frameworks, and platforms. My own journey has taken me through the worlds of backend development, cross-platform apps with React Native and Flutter, and of course, native iOS. And after seeing what each has to offer, I’ve come to a clear and exciting realization: my true passion lies in building for native iOS.

While the standard property wrappers handle most state management needs, you will often encounter situations where the shape of your state doesn’t perfectly match the requirements of a SwiftUI view. For example, a view might need a Binding<String>, but your model provides a Binding<String?>. Or a view needs to bind to the associated value of an enum case.

In SwiftUI, managing the state of your application—the data that drives your UI—is a fundamental concept. SwiftUI provides a set of powerful property wrappers that handle view updates automatically when your data changes. This guide explores the core tools: @State, @StateObject, @ObservedObject, and @Published.

I am ready to systematically review the iOS knowledge, so I have this simple Swift 6 Programming study notes.

Today I start to prepare Duolingo English Test. I made honey sweet potato chips for the children today, and the children loved it.
