If there isn't a way to disable Presentations, would there at least be a way to guard against this error and handle it if it occurs, instead of crashing the app?

Hi @Vision Pro Engineer , thank you for your answer. The reason the browser window is opened in a volume is that the concept of the application is to have the element move alongside the user as he moves around. We did not find a way to accomplish this with WindowGroups, which seem designed to remain static in the 3D space.
Relevant code:
import SwiftUI
import WebKit
struct WebView: UIViewRepresentable {
typealias UIViewType = WKWebView
let webView: WKWebView
func makeUIView(context: Context) -> WKWebView {
return webView
}
func updateUIView(_ uiView: WKWebView, context: Context) {
}
}
import SwiftUI
import WebKit
class WebViewModel: ObservableObject {
let webView: WKWebView
let url: URL
@Published var canGoBack: Bool = false
@Published var canGoForward: Bool = false
@Published var urlString: String = ""
init() {
let config = WKWebViewConfiguration()
webView = WKWebView(frame: .zero, configuration: config)
url = URL(string: "https://www.google.com")!
setupBindings()
loadURL()
}
private func setupBindings() {
webView.publisher(for: \.canGoBack)
.assign(to: &$canGoBack)
webView.publisher(for: \.canGoForward)
.assign(to: &$canGoForward)
}
func loadURL() {
let urlElements = urlString.split(separator: ".")
print(urlElements.count)
if (urlElements.count > 1 && !urlString.contains(" ")) {
f (!urlString.lowercased().contains("https://")) {
urlString = String("https://").appending(urlString)
}
} else {
urlString = "https://www.google.com/search?q=" + urlString.replacingOccurrences(of: " ", with: "+")
}
guard let url = URL(string: urlString) else {
return
}
webView.load(URLRequest(url: url))
}
func goForward() {
webView.goForward()
}
func goBack() {
webView.goBack()
}
}
import SwiftUI
struct BrowserView: View {
@StateObject var model: WebViewModel
var body: some View {
ZStack(alignment: .bottom) {
Color.black
.ignoresSafeArea()
VStack(spacing: 0) {
HStack(spacing: 10) {
HStack {
TextField("Enter an url", text: $model.urlString)
.keyboardType(.URL)
.textInputAutocapitalization(.none)
.padding(10)
.onKeyPress(.return) {
model.loadURL()
return .handled
}
Spacer()
}
.background(Color.gray)
.presentationCornerRadius(30)
Button("Go", action: {
model.loadURL()
})
.padding(10)
}
.padding(10)
WebView(webView: model.webView)
HStack(spacing: 10) {
Button(action: {
model.goBack()
}, label: {
Image(systemName: "arrowshape.turn.up.backward")
})
.disabled(!model.canGoBack)
Button(action: {
model.goForward()
}, label: {
Image(systemName: "arrowshape.turn.up.right")
})
.disabled(!model.canGoForward)
Spacer()
}
.padding(10)
}
}
}
}
Some potential ways to fix this:
Disable presentations entirely, and have websites use a fallback.
Allow me to create handlers for when presentations would be created and do something else.
Allow presentations to be created as Attachments, which is how the WKWebView is implemented.
I have looked at the WKWebView documentation, but haven't found a way to attempt these.
