I once successfully saw my local notifications test on the device, and in fact iOS seemed to trigger the fetch three times, each about about fifteen minutes apart, but then it never occurred again. I have tried logging in the fetch handers, and also written code to send local notifications. I've opened the app, closed the app (not killed the app!), waited hours and days. When running on the device and not connected to Xcode, my code is not executing. Of course, I've looked at the other SO questions hoping someone else experienced the same thing.I have verified that the device has background refresh enabled within settings.My tests show code executing in the performFetch method in about 0.3 seconds (so it's not taking a long time).I have successfully tested with a new scheme as shown in another SO answer ( )

I have (successfully!) tested with the simulator and device using Xcode's Debug/SimulateBackgroundFetch scheduleLocalNotification:localNotification] UILocalNotification* localNotification = init] NSTimeInterval timeElapsed = [fetchEnd Fetch Duration: %f seconds', timeElapsed) [FeedParser parseFeedAtUrl:url result = UIBackgroundFetchResultNoData setObject:fetchStart forKey:kLastCheckedContentDate] (void)application:(UIApplication *)application performFetchWithCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandlerįetchCompletionHandler = completionHandler I have implemented application:performFetchWithCompletionHandler void (^fetchCompletionHandler)(UIBackgroundFetchResult) tell the system we want background fetch In application:didFinishLaunchingWithOptions I have tried various intervals with setMinimumBackgroundFetchInterval, including UIApplicationBackgroundFetchIntervalMinimum - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

I have enabled 'Background fetch' under 'Background modes' under 'Capabilities' on the target in Xcode.

My test device is running iOS 9.3.5 (my deployment target is 7.1).

While testing in Xcode it works, when running on the device it doesn't!

I am trying to get iOS background app fetch to work in my app.

How does the app fetch work
