NavigationLink必须始终在NavigationView内部，无论如何。如果你想把它放在外面，比如在.searchable里面，你应该使用programmatic navigation with isActive。

struct ContentView: View {
    
    @State private var term = ""
    @State private var isPresenting = false
    
    var body: some View {
        NavigationView {
            
            /// NavigationView must only contain 1 view
            VStack {
                Text("Hello, world!")
                    .padding()
                
                /// invisible NavigationLink
                NavigationLink(destination: SecondView(), isActive: $isPresenting) { EmptyView()}
            }
        }
        .searchable(text: $term) {
            Button { isPresenting = true } label: {
                Text("Go to second view")
            }
        }
    }
}

struct SecondView: View {
    var body: some View {
        Text("Goodbye!")
            .padding()
    }
}

的数据

我的2美分使用苹果文档的数据。
一些注意事项：
1.您必须在NavigationView中包含列表（iOS17的NavigationStack，因为NavigationView已被弃用）
1.即使苹果的文档（和网络上的许多）似乎是这样说的，没有Nav..XX不工作：尝试自己评论Nav..XX

import SwiftUI

 struct Ocean: Identifiable {
     let name: String
     let id = UUID()
 }

 struct ContentView: View {

 private var oceans = [
     Ocean(name: "Pacific"),
     Ocean(name: "Atlantic"),
     Ocean(name: "Indian"),
     Ocean(name: "Southern"),
     Ocean(name: "Arctic")
 ]

 @State private var searchText = ""

 var body: some View {
     NavigationStack { // Try to commenting out.

         let filtered = self.oceans.filter { (ocean : Ocean) in
             return ocean.name.uppercased().contains(searchText.uppercased()) || searchText.isEmpty
         }
         List(filtered) { (ocean: Ocean) in
             Text(ocean.name)
         }
         .searchable(text: $searchText, prompt: "")
     }
 }
