we've a socket.io client for chats and for some data fetching also, so the problem is when we put the app in background in IOS, after 30 seconds it disconnects, yes it connects again when you put the app on foreground, but i need it to stay connected for at least 5 minutes.
Tried this code also from chatgpt.
import UIKit
import Capacitor
import Firebase
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
var backgroundTask: UIBackgroundTaskIdentifier = .invalid
var timer: Timer?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
FirebaseApp.configure()
return true
}
func keepSocketAliveForTenMinutes() {
// Start a background task to extend runtime
backgroundTask = UIApplication.shared.beginBackgroundTask(withName: "KeepSocketAlive") {
// End the task if time expires
UIApplication.shared.endBackgroundTask(self.backgroundTask)
self.backgroundTask = .invalid
}
// Start a timer to keep the socket alive
timer = Timer.scheduledTimer(withTimeInterval: 10 * 60, repeats: false) { [weak self] _ in
self?.endBackgroundTask()
}
}
func endBackgroundTask() {
if backgroundTask != .invalid {
UIApplication.shared.endBackgroundTask(backgroundTask)
backgroundTask = .invalid
}
timer?.invalidate()
timer = nil
}
func applicationDidEnterBackground(_ application: UIApplication) {
// Start keeping the socket alive for 10 minutes
keepSocketAliveForTenMinutes()
}
func applicationWillEnterForeground(_ application: UIApplication) {
// End the background task when the app returns to the foreground
endBackgroundTask()
}
func applicationWillTerminate(_ application: UIApplication) {
endBackgroundTask()
}
// Other methods ...
}

The problem is when we put the app in background in IOS, after 30 seconds it disconnects
This is expected behaviour. Apps on iOS cannot execute indefinitely in the background and network connections do not stay "alive" once an app is suspended. Timers do not fire when an app is suspended.
I need it to stay connected for at least 5 minutes
This is not possible. iOS apps have a maximum background execution of 30 seconds.
Push notifications are an appropriate strategy for notifying the user of incoming messages when the app is not in the foreground.
