Thank you very much for this detailed answer!
I double checked my code against your suggestions and read the documentation with all the edge cases but I have not been able to get it to work.
I'm a bit confused by what you're saying here. That's the function the system uses to pass URLs into your app. Why haven't you implemented it?
Sorry for the misunderstanding. What I meant to say is that I implemented this function but it is not being called.
Basically I implemented the functions from which I would expect the url variables and a ContentView struct then proceeds to display whatever it is that has been written to AppState.shared.startParam and it only ever displays: URL Parameters: launchOptions:nil.

First, the "nil" argument is probably caused by this:
"If the app supports scenes, this is nil. For information about the possible keys in this dictionary and how to handle them, see UIApplication.LaunchOptionsKey."

The App does not support scenes.

Finally, application(_:open:options:) add it's own layer of complications:

I return true in all the functions. And the app does not support scenes.
CustomURLNativeIOSApp.swift:
import SwiftUI
class AppState: ObservableObject {
static let shared = AppState()
@Published var startParam: String = "No URL parameters detected yet"
private init() {}
}
@main
struct iOSApp: App {
@UIApplicationDelegateAdaptor(AppDelegate.self)
var appDelegate: AppDelegate
@ObservedObject private var appState = AppState.shared
var body: some Scene {
WindowGroup {
ContentView()
.environmentObject(AppState.shared)
}
}
}
//customurlios://open?test=things
class AppDelegate: NSObject, UIApplicationDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]?) -> Bool {
print("URL received launchOptions:", launchOptions ?? [:])
let param = "launchOptions:\(String(describing: launchOptions))"
AppState.shared.startParam = param
print("Set startParam to: \(param)")
return true
}
func application(_ application: UIApplication, handleOpen url: URL) -> Bool {
print("URL received handleOpen:", url.absoluteString)
let param = "handleOpen: \(url.absoluteString)"
AppState.shared.startParam = param
print("Set startParam to: \(param)")
return true
}
func application(_ application: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
print("URL received open url:", url.absoluteString)
let param = "url: \(url.absoluteString) options:\(options.count)"
AppState.shared.startParam = param
print("Set startParam to: \(param)")
return true
}
}
ContentView.swift:
import SwiftUI
struct ContentView: View {
@State private var showContent = false
@EnvironmentObject var appState: AppState
var body: some View {
VStack {
Button("Click me!") {
withAnimation {
showContent = !showContent
}
}
Text("URL Parameters: \(appState.startParam)")
.font(.system(size: 14))
.padding()
.background(Color.gray.opacity(0.1))
.cornerRadius(8)
if showContent {
VStack(spacing: 16) {
Image(systemName: "swift")
.font(.system(size: 200))
.foregroundColor(.accentColor)
Text("SwiftUI: Hello")
}
.transition(.move(edge: .top).combined(with: .opacity))
}
}
.frame(maxWidth: .infinity, maxHeight: .infinity, alignment: .top)
.padding()
.onAppear {
// Print the current value for debugging
print("ContentView appeared, startParam: \(appState.startParam)")
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
.environmentObject(AppState.shared)
}
}

Still cannot find my mistake...
