有时候还挺费解为什么 Mac 的 Color Picker 会有“蜡笔”面板，原来是工程师自娱自乐的产物。

> On a roll, I decided to also knock out a “crayon picker”. At this point, to be clear, the color picker was working and I felt I understood it well enough. As I say, I was kind of just having some fun now.

> And I wrote the crayon picker because it seemed to me to be the kind of thing Apple was all about: HSL, RGB — these were kind of nerdy color spaces — a box of crayons is how the rest of us picked colors.

Xcode 26 从 beta 1 升级到 beta 2 以后，在设置里看不到 beta 1 的模拟器也无法卸载它。似乎模拟器安装的位置受 SIP 保护，如果升级之前忘记卸载旧的模拟器想要 reclaim 这 10GB 的空间，还得先把 beta 1 的 Xcode 安装回来才行😞。

看到矩形的 focusRing 就下意识地感慨，这界面也是 SwiftUI 的了。

对比 AppKit 按钮的 focusRing 的动画质感和自动的形状处理，其实也并不是很难实现的效果，但我们可能真的回不到追求极致细节的那个时代了。
