Hi, I'm no Obj-C developer, but I need to use it when interacting with the Zebra barcode scanner API. I have created a brdging header which works, but I can get this function to return any data. swift func sbtGetAvailableScannersList(_ availableScannersList: AutoreleasingUnsafeMutablePointerNSMutableArray?!) - SBT_RESULT I read on stackoverflow that I can declare it like this: swift var availableScanners: NSMutableArray? scanner?.sbtGetAvailableScannersList(&availableScanners) if let _scanners = availableScanners { for scanner in _scanners { if let scanner = scanner as? SbtScannerInfo { listOfScanners.append(scanner) } } } but the array is always nil. These is a delegate method that fires whenever a scanner get available, and it works, so I know that at least in theory, the array should contain that scanner. This is the Obj-C implementation in the demo.app provided by Zebra Objective-C (void)fillScannersList:(NSMutableArray**)list {     NSMutableArray *available = [[NSMutableArray alloc] init];     NSMutableArray *active = [[NSMutableArray alloc] init];     if (m_DcsSdkApi != nil)     {         if ([m_DcsSdkApi sbtGetAvailableScannersList:&available] == SBT_RESULT_FAILURE)         {             dispatch_async(dispatch_get_main_queue(),                 ^{                     [self showMessageBox:@"Search for available scanners has failed"];                 }             );         }         [m_DcsSdkApi sbtGetActiveScannersList:&active];         /* nrv364: due to auto-reconnect option some available scanners may have          changed to active and thus the same scanner has appeared in two lists */         for (SbtScannerInfo *act in active)         {             for (SbtScannerInfo *av in available)             {                 if ([av getScannerID] == [act getScannerID])                 {                     [available removeObject:av];                     break;                 }             }         }         if ((list != nil) && (*list != nil))         {             [*list removeAllObjects];             [*list addObjectsFromArray:available];             [*list addObjectsFromArray:active];         }     }     [available release];     [active release]; }

Hi,I have a tableView where I have configured some actions. One of them is to scan or input a serial number for a cart Item. The flow goes like this:trailingSwipeActionalertController ask if user wants to use keyboard og barcode scanner Barcode -> calls barecode scanner to start scanning --> scan received --> update model[indexPath.row]Keyboard --> new alertController asking for input --> input received --> update model[indexPath.row]Reload cellWhat is the best approach to acheive the model update? Is seems most correct to extend all method calls to pass forward the model instance at the correct index, but it's also cumbersome. A far easier approach is to have a variable in the ViewController as "selected row" and use that as the index whenever I need it. But again, that could easily fall out of sync if I forget to update it one place.

Hi,How can I create a tableViewCell with a lot of elements, but having the cell increase/decrease height dependent on which elements that are present?I.e: I always have an image and a title, but I could also have subtitle, tags, an icon + +. If I only have image and title, I want the title to be aligned to the center of the image, and the cell to be e.g 80 height. But If I have subtitle and tags, I want the height to be higher and the title to align to the top line of the image with tags and subtitles below.
