As others have mentioned, this is caused by not having previous called the completionHandler after widgetPerformUpdateWithCompletionHandler has been called. You need to make sure that completionHandler is called no matter what.

The way I suggest handling this is by saving the completionHandler as an instance variable, and then calling it with failed in viewDidDisappear:

@property(nonatomic, copy) void (^completionHandler)(NCUpdateResult);
@property(nonatomic) BOOL hasSignaled;

- (void)widgetPerformUpdateWithCompletionHandler:(void (^)(NCUpdateResult))completionHandler {
    self.completionHandler = completionHandler;
    // Do work.
}

- (void)viewDidDisappear:(BOOL)animated {
  [super viewDidDisappear:animated];
  if (!self.hasSignaled) [self signalComplete:NCUpdateResultFailed];
}

- (void)signalComplete:(NCUpdateResult)updateResult {
  NSLog(@"Signaling complete: %lu", updateResult);
  self.hasSignaled = YES;
  if (self.completionHandler) self.completionHandler(updateResult);
}
