Question

我最近更新到Xcode 11.3，现在我的ForEach语句中以前正常工作的动画延迟失败了。下面是我的代码的简化版本。

谢谢

import SwiftUI

struct ContentView: View {

    @State var show: Bool = false

        var transition: AnyTransition {

            let insertion = AnyTransition.move(edge: .trailing)

            let removal = AnyTransition.move(edge: .leading)

            return .asymmetric(insertion: insertion, removal: removal)
        }

    var body: some View {
        VStack {

            Button(action: { withAnimation { self.show.toggle() } } ) {
                Text("start animation")
            }
            if show == true {
                test()
                .transition(transition)
            }
        }
    }

}


struct wordArray: Identifiable{

    var id = UUID()
    var words: String

}

struct test: View{

    let circleArray = [

        wordArray(words: "This"),
        wordArray(words: "Should"),
        wordArray(words: "Be"),
        wordArray(words: "Delayed"),

    ]

    var body: some View{

        VStack{

            ForEach(circleArray) { wordArray in
                Text("\(wordArray.words)")
                    .animation(Animation.easeInOut.delay(0.5))
            }

            Text("like")
                .animation(Animation.easeInOut.delay(0.5))

            Text("This")
                .animation(Animation.easeInOut.delay(1))


        }.frame(width: UIScreen.main.bounds.width)
    }
}

这可能是由于双VStack。您可以在testView中将let lovers = document.getElementsByClassName("lover")[0]; lovers.style.color = "red";更改为VStack。

SwiftUI ForEach没有动画延迟
