ios – .searchable in SwiftUI and odd conduct

[Using Xcode 15.3 with Simulator running iPhone 15, iOS 17.4]

I’m seeing what I feel is odd conduct with searchable in a NavigationStack. Code beneath is an instance that exhibits the difficulty.

After I navigate to a view from a NavigationStack after which navigate again, the search bar seems. Moreover, if there isn’t a navigation title on the NavigationStack, the search bar seems instantly.

I do not plan on not utilizing navigation titles. It simply appears odd to me and I do not perceive the connection between the title or navigation and the search bar.

//
//  ContentView.swift
//  NavigationSearchTest
//

import SwiftUI

///
struct StringView: View
{
    let string: String
    
    var physique: some View
    {
        Textual content(string)
            .navigationTitle("String")
    }
}

///
struct ContentView: View
{
    let strings = ["String 1", "String 2", "String 3"]
    
    @State var searchText: String = ""
    
    var physique: some View
    {
        NavigationStack
        {
            Listing
            {
                ForEach(strings, id: .self)
                {
                    s in
                    
                    NavigationLink(vacation spot: StringView(string: s))
                    {
                        Textual content(s)
                    }
                }
            }
            .searchable(textual content: $searchText)
            #if false // If false, search bar seems instantly
            .navigationTitle("Strings")
            #endif
        }
    }
}

#Preview {
    ContentView()
