⏪上集節目回顧

📰一週開發者新聞

WWDC21 時間宣布。AR 眼鏡、眼鏡上的日期
通過並且已實作在 Swift 5.5 SE-0307 Allow interchangeable use of CGFloat and Double types
iOS 14.5 SwiftUI 坑



⭐️SwiftUI in Production

Kean: The SwiftUI Experiment
iOS 14 才有的功能:@StateObject、LazyV(H)Stack、fullScreenCover()…
對 View 心境上的轉換: View Layout ,Debug ,與 Trace
較大專案的畫面是對到哪個 View,不好 trace
Preview 莫名掛掉
Data flow: ObservedObject 是 reference type,沒有一個統一接受 action 來 mutate state 的介面
SwiftUI 用在 Production 的好:fast iteration,code reuse
坑: Generic,SE-0307,Layout System (align views),potential performance issue (useMemo)
可以回去聽 46: 推你入坑 SwiftUI 不後悔
