Hi, I'm trying to test the new BackgroundTasks framework.* Xcode 11.0 beta 3* On the simulator, the submit task raises an error* On my iPhone 7 beta 2, task doesn't be triggeredHere is the steps :- I checked the "Background Processing" check box in capabilities- I added com.example.refresh in the Info.plist<key>BGTaskSchedulerPermittedIdentifiers</key> <array> <string>com.example.refresh</string> </array>- I put the following code in the application didFinishLaunchingWithOptions :// Background tasks testing if (@available(iOS 13.0, *)) { [[BGTaskScheduler sharedScheduler] registerForTaskWithIdentifier:@"com.example.refresh" usingQueue:nil launchHandler:^(__kindof BGTask * _Nonnull task) { UILocalNotification *notification = [[UILocalNotification alloc] init]; notification.fireDate = [NSDate date]; notification.alertBody = @"YEAH"; [[UIApplication sharedApplication] presentLocalNotificationNow:notification]; [task setTaskCompletedWithSuccess:YES]; }]; [[BGTaskScheduler sharedScheduler] cancelAllTaskRequests]; BGProcessingTaskRequest *bgTaskRequest = [[BGProcessingTaskRequest alloc] initWithIdentifier:@"com.example.refresh"]; NSDate *d = [NSDate date]; int nbMin = 5; [bgTaskRequest setEarliestBeginDate:[d dateByAddingTimeInterval:(nbMin*60)]]; [bgTaskRequest setRequiresNetworkConnectivity:NO]; [bgTaskRequest setRequiresExternalPower:NO]; NSError *e; [[BGTaskScheduler sharedScheduler] submitTaskRequest:bgTaskRequest error:&e]; NSLog(@"ERROR TASK : %@", e); NSLog(@"Task planified at %@", [d dateByAddingTimeInterval:(nbMin*60)]); } else { // Fallback on earlier versions }The notification is never triggered.
