Questions[xcode]

I have a problem, I am working with Xcode 11.3.1 and when I run my app, which was created in a previous version of Xcode, my statusBar is not visible, I don't know if it is a bug in the emulators or if I need some configuration .

If I run my app it appears like this.

I don't understand why the statusBar is not being shown, I have tried with this code but it doesn't work for me.

self.navigationController?.setNavigationBarHidden(false, animated: true)
if #available(iOS 13.0, *){
  let navBarAppearance = UINavigationBarAppearance()
  navBarAppearance.configureWithOpaqueBackground()
  navBarAppearance.titleTextAttributes = [.foregroundColor: UIColor.white]
  navBarAppearance.largeTitleTextAttributes = [.foregroundColor: UIColor.white]
  navBarAppearance.backgroundColor = UIColor.red
  self.navigationController?.navigationBar.scrollEdgeAppearance = navBarAppearance
  self.navigationController?.navigationBar.standarAppearance = navBarAppearance
}

But I have not been able to show the status bar.

I made my application in iOS 12 with Xcode 10 and when I updated to iOS 13 and Xcode 11 the storyboard came out this way, only when I used a Navigation Controllers. Could you give me a hand. Thank you!

I am new to app development for the app store. Recently I had to develop a couple of applications and I published them, the problem is that soon I will have to change my Mac to develop and I will need to keep updating the applications. According to me, what is necessary is to export the distribution certificate (the .p12) that I requested and used to publish the applications. Is it enough to install that certificate on the new Mac and the provisioning profile of each application and I should be able to continue working from another computer?

Another issue is that several iPhone certificates appear in the keychain but they are not distribution certificates. Should those be considered as well? Greetings.

I am trying to bulk insert data into Realm, but it is making it very slow.

this is my code:

            let realm = try! Realm()


            let group = GroupRealm()

            group.id = 1
            group.name = "test"

            try! realm.write { 
                realm.add(group)
            }

            var product = [String:AnyObject]()
            product["id"] = "" as AnyObject!
            product["code"] = ("") as AnyObject!
            product["detail"] = ("") as AnyObject!
            product["onHand"] = (0) as AnyObject!
            product["price"] = (0) as AnyObject!
            product["isSerialized"] = (0) as AnyObject!
            product["isLotNumber"] = (0) as AnyObject!

            var groupProduct = [String:AnyObject]()
            groupProduct["group"] = group as AnyObject!

            for r in 0..<300 {
                realm.beginWrite()
                for i in 0..<100 {
                    product["id"] = "\(i)-\(r)" as AnyObject!
                    realm.create(ProductRealm.self, value: product, update: true)

                    groupProduct["id"] = "\(i)-\(r)" as AnyObject!
                    groupProduct["product"] = product as AnyObject!
                    realm.create(GroupProductRealm.self, value: groupProduct, update: true)
                }
                try! realm.commitWrite()
            }

The objects I am using are these:

class ProductRealm: Object {
    public dynamic var id: String = ""
    public dynamic var code: String = ""
    public dynamic var detail: String = ""
    public dynamic var onHand: Int = 0
    public dynamic var price: Double = 0
    public dynamic var isSerialized: Int = 0
    public dynamic var isLotNumber: Int = 0
    override static func primaryKey() -> String? {
        return "id"
    }
}

class GroupProductRealm: Object {
    public dynamic var id = ""
    public dynamic var group: GroupRealm!
    public dynamic var product: ProductRealm!
    override static func primaryKey() -> String? {
        return "id"
    }
}
class GroupRealm: Object {
    public dynamic var id = 1
    public dynamic var name = ""
    public dynamic var update = Date()
    override static func primaryKey() -> String? {
        return "id"
    }
}

Testing on my iphone 5s to insert 30000 records takes over 30 seconds, while on an old project I have with sqlite it takes around 16 seconds.

I've read that realm is much faster at this than sqlite, so I know it's my mistake, but I can't find the D:

I'm having problems in the iPad view, I'm trying to make a table in which each cell will consist of a textLabeland a button UIButton, when I try it on an iPhone the view looks fine, but when I try it with an iPad it looks like this :

The code I have is the following:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    NSString *simpleTable = [NSString stringWithFormat:@"simpleTableIdentifier%ld", (long)indexPath.row];
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTable];

    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTable];
    }

    Centro_DTO *cen_datos = [[Centro_DTO alloc] init];
    cen_datos = [self.computersCentros objectAtIndex:indexPath.row];

    NSString *currentL = ([Global sharedMySingleton].test);

    if ([currentL isEqualToString:@"es"]) {

        cell.textLabel.text = cen_datos.nombreES;
    } else if ([currentL isEqualToString:@"ca-ES"]) {

        cell.textLabel.text = cen_datos.nombreCA;
    } else if ([currentL isEqualToString:@"en"]) {

        cell.textLabel.text = cen_datos.nombreEN;
    }

    cell.textLabel.textColor = [UIColor colorWithRed:(0/255.0) green:(44/255.0) blue:(82/255.0) alpha:1];
    cell.textLabel.font = [UIFont systemFontOfSize:13.0];
    cell.accessoryType = UITableViewCellAccessoryNone;

    UIButton *centroActivo = [[UIButton alloc] init];
    centroActivo.highlighted = NO;

    int orientation = [[UIApplication sharedApplication]statusBarOrientation];

    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad || (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone && orientation != UIDeviceOrientationPortrait)) {
        centroActivo.frame = CGRectMake(350.0, 15.0f, 20.0f, 20.0f);
    } else {
        centroActivo.frame = CGRectMake(290.0, 15.0f, 20.0f, 20.0f);
    }
    centroActivo.tag = indexPath.row;
    [centroActivo setImage:[UIImage imageNamed:@"checkbox_checked.png"] forState:UIControlStateSelected];
    [centroActivo setImage:[UIImage imageNamed:@"checkbox_unchecked.png"] forState:UIControlStateNormal];
    [centroActivo addTarget:self action:@selector(checkboxSelected:) forControlEvents:UIControlEventTouchUpInside];

    if (cen_datos.activo == 1) {

        [centroActivo setSelected:YES];
    } else {

        [centroActivo setSelected:NO];
    }

    cell.selectionStyle = UITableViewCellSelectionStyleNone;
    [cell.contentView addSubview:centroActivo];

    return cell;
}

and what I want is for it to look like this on the ipad:

Any suggestion what it could be?

PS: I'm pretty new with objective-c development
