ios – Common Hyperlink opens app however fails to save lots of user_id in UserDefaults

I am utilizing Common Hyperlinks in my iOS app, and the hyperlink accurately opens the app as anticipated. Nonetheless, I am having hassle saving the user_id parameter from the URL to UserDefaults. Right here’s my setup:

import UIKit

class AppDelegate: UIResponder, UIApplicationDelegate {
    func utility(_ utility: UIApplication, proceed userActivity: NSUserActivity, restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void) -> Bool {
        guard userActivity.activityType == NSUserActivityTypeBrowsingWeb,
              let incomingURL = userActivity.webpageURL else {
            return false
        }

        // Test for "open" in path and get the "user_id" question parameter
        if incomingURL.pathComponents.accommodates("open"),
           let userID = incomingURL.queryParameters?["user_id"] {
            
            // Try to save lots of userID to UserDefaults
            UserDefaults.normal.set(userID, forKey: "user_id")
            return true
        }

        return false
    }
}

URLExtensions.swift

import Basis

extension URL {
    var queryParameters: [String: String]? {
        var params = [String: String]()
        let queryItems = URLComponents(url: self, resolvingAgainstBaseURL: false)?.queryItems
        queryItems?.forEach {
            params[$0.name] = $0.worth
        }
        return params
    }
}

How i name the consumer id

import SwiftUI

struct ContentView: View {
    @State non-public var userId: String = ""  // State for user_id to show it within the UI

    var physique: some View {
        VStack {
            Textual content("Consumer ID: (userId.isEmpty ? "Not Out there" : userId)")
                .foregroundColor(.white)
                .padding()

            Button("Test Consumer ID") {
                // For testing, manually fetch and show UserDefaults worth
                userId = getUserId()
                print("Fetched Consumer ID:", userId)
            }
        }
        .onAppear {
            // Fetch user_id when the view seems
            userId = getUserId()
            print("Consumer ID on seem:", userId)
        }
        .background(Shade.grey)
    }

    func getUserId() -> String {
        // Retrieves user_id from UserDefaults
        return UserDefaults.normal.string(forKey: "user_id") ?? ""
    }
}

The hyperlink seems to be like this: https://instance.com/open?user_id=a4a64be8-9a74-4960-8f0b-80aee292614f

The app opens accurately with the Common Hyperlink, however the user_id just isn’t saved to UserDefaults as anticipated.

I’ve verified the URL construction and that the user_id parameter exists within the hyperlink. Nonetheless, when retrieving UserDefaults.normal.string(forKey: "user_id") later, it’s returning nil.

Am I lacking one thing in my code that’s stopping user_id from being saved?
