Issues with Background Fetch Not Updating Data in iOS 16.1 Using Swift
I'm wondering if anyone has experience with I'm experimenting with I'm updating my dependencies and I'm working on a personal project and I'm sure I'm missing something obvious here, but I'm having trouble with the background fetch functionality in my iOS app. Despite implementing the `performFetchWithCompletionHandler` method, it seems like the fetch isn't being called consistently, especially when the app hasn't been opened for a while. In my implementation, I have set a minimum background fetch interval. However, when I check the logs, I only see the fetch being called once every few hours, even though my settings indicate it should be more frequent. Here's a snippet of my code: ```swift import UIKit import BackgroundTasks @main class AppDelegate: UIResponder, UIApplicationDelegate { func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool { UIApplication.shared.setMinimumBackgroundFetchInterval(UIApplication.backgroundFetchIntervalMinimum) return true } func application(_ application: UIApplication, performFetchWithCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) { // Simulate a data fetch fetchData { newData in if newData { completionHandler(.newData) } else { completionHandler(.noData) } } } func fetchData(completion: @escaping (Bool) -> Void) { // Simulated network call DispatchQueue.global().asyncAfter(deadline: .now() + 2) { completion(true) // Simulated new data } } } ``` I've also made sure that Background Modes are enabled in the app capabilities for "Background fetch". When testing on a physical device, I am using iPhone 13 running iOS 16.1. To troubleshoot, I've verified that the app is not getting suspended and that the fetch is indeed configured. However, I'm still not seeing the frequency I expect. Could it be related to the app's usage patterns or the way iOS manages background tasks? Any guidance on reliable ways to test background fetch would be greatly appreciated. This is part of a larger service I'm building. Thanks in advance! Am I missing something obvious? Has anyone else encountered this? I recently upgraded to Swift LTS. I'd really appreciate any guidance on this. Any help would be greatly appreciated! For reference, this is a production mobile app.
