13的話

近期許多大廠都在裁員。讓我想到高中導師給我印象最深刻的一句話：「301（他喜歡用班號稱呼我們），人才到哪裡都是人才。」

如果你有受到影響的話，相信可以順利度過這關的。

我現在服務的公司還在台灣大舉招募人才，各種職缺都有，而且我覺得做的東西既有趣又有挑戰性，待遇也沒在客氣的。有興趣的朋友可以直接回信聊聊。

我下週請假，會停刊一次。

🔭A vision for variadic generics in Swift

許多 SwiftUI 使用者都知道 @ViewBuilder 只能放 10 個 view，而且是透過 hard-coded 1~10 個 view 版本的 overloading😂

顯然是個 workaround，看起來、用起來都有些無奈。

要真正解決這個問題，就需要語言本身支援 variadic generics，也就是本提案的重點。

⏳Swift 5.7 / Xcode 14 incremental build time 10x slower than Swift 5.6 / Xcode 13

如果有覺得 Xcode 14 比較慢的話，可以試試看。

Thomas @tclementdev

If you have build time issues with Xcode 14. "We've just tried SWIFT_USE_INTEGRATED_DRIVER=NO in all our targets and it massively brings down incremental compile times!"

🍁Maple Diffusion Swift Package

離線的 AI 圖片產生器，只要一個 Swift Package 就可以開始玩了。而且速度挺不賴的。

Morten Just @mortenjust

What if you could add Stable Diffusion in one line of code in a native iOS or Mac app?

It's fully offline and native (via Metal). Here's a full app, including UI. You can see the image being generated realtime behind the blur.

It's faster than any local offline method I've tried; 2x PyTorch, giving me ~0.3 it/sec = 6 seconds You can play with the Swift Package here - it wraps @madebyollin's MPSGraph implementation of the pipeline (link in repo)

Apple 的 VR/AR 相關技術可能會打造出怎樣的產品跟使用者體驗，相信有在用心觀察的人，都可以想像出很多東西。這個 Twitter thread 列舉了不少，值得一讀。

Hrafn Thorisson @hrafntho

What we know so far about Apple’s VR/AR plans and headsets (THREAD). More than summarize facts, my aim is to paint a picture of what Apple’s platform may be, from perspective of an industry veteran with +10 year experience and a successful VR/AR company focused on innovation.

我看了這推才知道 SwiftUI 從 iOS 15 就有 .safeAreaInset 可以放東西，是很實用的排版方式。（文章版）

Natalia Panferova @natpanferova

If we need to permanently pin a view to the bottom of the screen in SwiftUI, we can place it inside safeAreaInset(edge: .bottom) modifier. If we use this method with a text field, it will also automatically move to the top of the keyboard when focused.

Is there a more productive way to spend my morning than digging out my old high school physics equations to build a SwiftUI rain drop simulator so that the droplets can accurately bounce off the clock hands? Almost Certainly. Is there a more fun way to spend my morning? Nope! 😁
