你可以插入多个警报消息在这下面的方式.
首先：为您想要处理的每个警报减少变量。

struct xyz : View 
{
    @State private var myFirstAlert : Bool = false
    @State private var mySecondAlert : Bool = false
 ....
}

            //Button stuff
        } label: { ZStack {Text("Bla"),....}} .alert(isPresented: self.$myFirstAlert){
         Alert(title: Text("Something went wrong!"))}
    .alert(isPresented: self.$mySecondAlert){
    Alert(title: Text("That was shitty"), message: Text("Something went totally wrong"), dismissButton: .default(Text("Urghs"), action: {}}

自定义提醒

您只需要创建一个自定义警报，以在单个视图中显示多个警报。

struct CustomAlertView<Content>: View where Content: View {
    
    @Binding var isPresented: Bool
    
    var onConfirm: () -> Void
    var title : String
    var message : String
    let content: () -> Content
    
    var body: some View {
        Group {
            if isPresented {
                content()
                    .alert(isPresented: $isPresented) {
                        Alert(
                            title: Text(title),
                            message: Text(message),
                            primaryButton: .cancel(Text("Yes"), action: {
                                onConfirm()
                            }),
                            secondaryButton: .default(Text("No"), action: {})
                        )
                    }
            } else {
                content()
            }
        }
    }
}

Usage:

struct HomeView: View {
    
    @State var alert1 : Bool = false
    @State var alert2 : Bool = false
        
    var body: some View {
        VStack {
            Spacer()
            Text("Custom Alerts")
            Button(action: {
                alert1 = true
            }) {
                Text("Alert 1")
            }
            Button(action: {
                alert2 = true   
            }) {
                Text("Alert 2")
            }
            Spacer()
        }
        .overlay(
            CustomAlertView(isPresented: $alert1, onConfirm: {    
            }, title: "Custom Alert 1", message: "This is Alert 1.") {
                Text("")
            }
        )
        .overlay(
        CustomAlertView(isPresented: $alert2, onConfirm: {   
        }, title: "Custom Alert 2", message: "This is Alert 2.") {
            Text("")
          }
        )
    }
