For me, my NavigationLinks were popping out whenever the app enters background, e.g. going back to iOS home screen or activating Control Center. I had found that I had an idle @Environment(\.scenePhase) var scenePhase in my App struct, that seem to be causing the uncommanded popping of the NavigationLink. Once I removed the scenePhase the problem was gone.

I have written a simple View to help anyone trying to isolate this issue that I discovered while trying to find the source of this warning. In my instance, I am using WKWebView to load specific sites that seems to trigger the warning when load(_ request: URLRequest) method is called. import SwiftUI import WebKit struct WebView: UIViewRepresentable { typealias UIViewType = WKWebView let webView: WKWebView func makeUIView(context: Context) -> WKWebView { return self.webView } func updateUIView(_ uiView: WKWebView, context: Context) { } } struct TestView: View { let webView = WKWebView(frame: .zero) var body: some View { ZStack { WebView(webView: self.webView) Button("Test", action: { Task.detached(priority: .background) { await self.webView.load(URLRequest(url: URL(string: "https://www.apple.com")!)) } }) } } } Even when attaching the load(_ request: URLRequest) method to a background thread seems to cause the warning. I am not expert in SwiftUI or the new Concurrency methods, but is there a 'proper' why that this method is supposed to be called off the main thread?
