這橋在紐西蘭的Mt.Cook 庫克山，我有走過耶，Hooker Valley Track路段會有經過三座吊橋到達Hooker Lake (胡克湖)，冬天來可以看見胡克冰川（Hooker Glacier）🏔️

假如有專案一年以上用 UIKit 開發功能很完整，總不能開新的專案，新的功能不做，全力花半年重新做 SwiftUI 版本。這時用蠶食鯨吞策略慢慢原有 StoryBoard UIKit 改嵌入 SwiftUI 🫸🏻🤏🏻 

MyViewController → MySwiftUIView
Press ‘Command + N’ to create a new Swift file named ‘MySwiftUIView’

import SwiftUI

class MySwiftUIViewHostingController: UIHostingController<MySwiftUIView> {
    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder, rootView: MySwiftUIView())
    }
}

struct MySwiftUIView: View {
    var body: some View {
        Text("Hello, World!")
    }
}

struct MySwiftUIView_Previews: PreviewProvider {
    static var previews: some View {
        MySwiftUIView()
    }
}

把 StoryBoard 的 class 改成 MySwiftUIViewHostingController
