This is how I request contacts framework access permission -(void)askUserToAccessContacts {   @try   {     if([CNContactStore class])     {       //iOS 9 or later       CNEntityType entityType = CNEntityTypeContacts;       if( [CNContactStore authorizationStatusForEntityType:entityType] == CNAuthorizationStatusNotDetermined)       {         CNContactStore * contactStore = [[CNContactStore alloc] init];         [contactStore requestAccessForEntityType:entityType completionHandler:^(BOOL granted, NSError * _Nullable error) {           if(granted){             DDLogVerbose(@"Permission granted for Contacts access...");           }         }];       }       else if( [CNContactStore authorizationStatusForEntityType:entityType]== CNAuthorizationStatusAuthorized)       {         DDLogVerbose(@"Permission granted for Contacts access !!!");       }       else       {         DDLogVerbose(@"Permission not granted for Contacts access !!!");       }     }         } @catch (NSException *exception) {           [[WriteLogger getWriteLogger] writeLog:@"AppDelegate" sourceClass:NSStringFromClass([self class]) methodName:NSStringFromSelector(_cmd) exception:exception exceptionDict:nil];   } } What could possibly cause the app to crash? By the way, this crash is not occurring all the time, it happens randomly when I install the app and launch it for the first time.

Hi,Currently I cannot clear a local notification in app (example: A reminder) which i scheduled from Notification Service Extension (NSE).i've tired clearing using the following APIs,NSArray *ids = @[@"Notify_from_app",@"Notify_from_extension"]; UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter]; [center removeAllDeliveredNotifications]; [center removePendingNotificationRequestsWithIdentifiers:ids];The above code works fine, when i try to clear a notification in NSE, which is scheduled from the same NSE. (if i try to clear from app, i can't)FYI, i'm able to clear all the notifications using the following code. (but my goal is to clear the notification using identifiers, a specific notification)UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter]; [center removeAllDeliveredNotifications]; [center removeAllPendingNotificationRequests];As per apple's documentation, the currentNotficationCenter object supports app extensions as well, that's why I'm able to schedule a local notifications from there.May be the currentNotificationCenter object for the app is not equal to the currentNotificationCenter object of NSE.This makes more sense because both have a separate container. (That's why we are not able to directly access the app's container from NSE.)Can i make a copy of the object in coredata and retrieve it in app to clear the notification?This dosen't feel like a good practice.I'm looking for a proper solution to clear the reminders, Please help me out.
