# 把現有專案跟潮潮的 SwiftUI 整合的入坑好時機！
> tldr: UIKit to SwiftUI

## the age of Declarative UI
* iOS: Swift UI
* iOS13 以上才支援🥺


## Small Components

* Use StackView as possible
* Use Xib as possible
* Use UIViewController than UIView
* Some of SwiftUI still be broken
* use UIKit instead

[VStackViewController](https://gist.github.com/d-date/294d4c791a273a502a68027a3a07d9f8)

## dataflow
* @ObservedObject

## using uivc in swiftui
too fast to read🤷🏼‍♂️ lol
just use VStack / HStack to layout...

## xib -> stactView
duo to preview in swiftUI can read `.xib`
use stack view instead xib

## Recap - UIKit to SwiftUI
* some of swiftui feature still be broken
* sometime need to use UIKit instead
* keeping components small is key factor to migrate
* 總之, 好像還有一些坑要踩, 並且要將您的畫面元件切割成小單元較佳
