我一直以为中国银行的万事达卡没有一点用，现在发现美区礼品卡只能使用万事达卡购买，银联卡会提示报错。

兑换礼品卡后，可以在 iOS 上直接订阅 ChatGPT Plus 服务（20美元/月），非常方便、安全。

我正在开发一款 Swift 学习应用「轻学 Swift」。

目标是通过项目驱动的方式，帮助零基础学习者一步步掌握 Swift / SwiftUI，并最终开发出自己的 App。

Building an app is like planting a tree. As your tree grows bigger, the shade it provides increases.

Of course, the downside is that when a tree becomes large enough, it blocks the sunlight from others. Obviously, my ImageSlim is one of the trees being overshadowed.
