ios 快說SwiftUI對iOS開發者影響 Apple 在這介WWDC對Cocoa Cocoa Touch 的Developer按了一次Reset，最起碼UI層面上。不少身邊友人看了簡介，立即中年危機上身，開始吐糟門檻又變低了一大半啊，新人湧現啊，存在感決失啊如此這般。但是真的便是這樣嗎？其實同時是，亦都不是。首先，對於開了簡介便下此判斷的人，我想說聲對不起，對你來說，可能真便如此。或許那麼簡單便下判斷，便是你那中年危機的成因。你需要的，不是讓Apple收回成命，而是重新審視這些年來，自己學會了什麼。不是說你一定便不求上進，只是可能在軟件開發的領域裡，你嚴重偏科了。讓我們認真聊聊吧。軟件領域，是進化得最快的一個行業。就算只談UI，在SwiftUI出現之前，
culture 開發者該如何學習的角度看別人產品 作為一個開放者，我們該怎樣去看別人的產品？ 要答這一個問題，便只能從所有軟件產品的根源說起⋯⋯ 電腦程式的本質，便是對電子活動的一層一層抽象。我們從電流的開合，數學的模擬，語言的整合，直到圖形系統，無一不是在更高的位面對低位面的一次抽象。 但即使是每天都進行著抽象活動的我們，也未必會時刻保持抽象的角度看待別人的產品。因為我們太習慣於具象的世界了。 上一次我看見的開發者集體跳崖事件，便是material design出現時。 抽象是一層一層地向上的，我們繼續談Material Design。 遊戲開始，請簡短說出什麼是Material Design。 3 2 1 ⋯⋯ 好了，對於你來說什麼是Material Design呢？ 是卡片、圓角？陰影、過渡？

development Fewer "guard" more flatMap Swift's guard syntax is good, I admitted. But it's not always the best choice in some cases. Let's consider: something.callback() { someOther:SomeOther? in guard let someOther = someOther else { return } functionTakeSomeOther(someOther) } Indeed,
development Map Map Map better in Swift Map function is quite a convenience method that often used in functional(mainly) programming. In Swift, all collection types(Array,Dictionary,Set...) support map. It take a closure that take element type from
