I have a 4GB video file in external storage that I want to copy into my iPhone. Thanks for explanation. You have no need to load all the content when you want copy files.

Actually, I don't understand the answers well. Then you should better stay in the original thread until you are confident enough that your issue is solved. When you think the problem is solved, mark the right answer as SOLVED. You may find another issue when one problem solved, in such case you should better start a new thread.

I got the answer to my previous question with this code. Do you really believe it would be the right direction?

yes all of then are global Well, frankly saying, you may need a lot more emojis which looks more severe. I often say to developers who say themselves as beginners, if you need effort to keep two or more arrays consistent, it is an indication of bad design and you should re-organize your code. You should better avoid using globals just for data passing. And you are still using non-Capitalized name for structs, that is making your code harder to read. Anyway, you have multiple UICollectionViews in each UITableView, so each UICollectionView needs to have own its dataSource. Only one global modelOfSeason would never work appropriately for multiple UICollectionViews. I will try to find how to fix your code with minimum modification, but it may take long. By the way, this thread is being too heavy for the Safari of my old MacBook Air. Maybe too many Code block (`) is not good for Safari, please try Text attachment` next time.

How can I control this issue? You usually do not load whole video content into a Data in iOS apps. How do you want to use the video file?

it tells me it doesn't find persistentContainer in scope even though I had persistent container declared in my appDelegate file. It depends where you wrote the line decoder.userInfo[.managedObjectContext] = persistentContainer.viewContext(). Please show enough context.

I thought this part was obvious. When everything is working as expected, it is reasonable to omit something obvious. But in this case, you need to find what's wrong. I tested with a brand-new project of iOS/App (Storyboard/Swift) with Xcode 12.4. Selected 'LaunchScreen.storyboard' (no whitespace between Launch and Screen in my case) in the navigation area Used + icon and dragged Image View into the View of the only ViewController of the 'LaunchScreen.storyboard'  (The image view is placed below the Safe Area of the View in view tree.) Expanded the image view by dragging the four edges to cover whole screen. Added an image to use as background into the project by dragging. (Chose Copy items if needed and some others.) Within the Attribute Inspector of the image view, chose the image (All other attributes kept as default.) The image I have chosen shows filling the view controller of Xcode or the simulator screen when run. (Without constraints, the image may not be placed in the center of the screen.) Can you follow this steps using the background image you want to use? Or do you think of anything you need to mention reading the steps?

Your new ArticlesParser lacks the property articles and it does not compile. Thing is, since the code for the XML parser is a bit more complicated, it's harder to pass variables around just like with Lunch Card. Once you finished (and once you made it work), ArticlesParser is as easy to use as JSONDecoder. Not sure how ArticleInfo is an integer Unfortunately, the current Xcode generates inappropriate diagnostics when there are type related errors. In your case, the real problem exists in this line: ArticleRow(image: article.img, title: article.title, author: article.author, date: article.date) The type of image is String, but the type of article.img is URL?. date in ArticleRow is String, but article.date is Date?. You need to pass the right type.

These lines all causes Cannot find in scope error: arrayCast.removeAll() arrayCreator.removeAll() arrayAiringSeason.removeAll() arrayOfSeasonsInt.removeAll() arrayCreatorName.removeAll() arraySeasonsEpisodes.removeAll() arregloDeArreglos.removeAll() arraySeasonsEpisodes.removeAll() arraySeasonsEpisodes2.removeAll() arraySeasonsEpisodes3.removeAll() arraySeasonsEpisodes4.removeAll() arraySeasonsEpisodes5.removeAll() arraySeasonsEpisodes6.removeAll() arraySeasonsEpisodes7.removeAll() arraySeasonsEpisodes8.removeAll() arraySeasonsEpisodes9.removeAll() arraySeasonsEpisodes10.removeAll() All of them are globals?

its only used as a global variable  Why are you making it global!!! Incredible...

Can you show the whole code of SelectedShowVC? As I suggested in your previous thread, we need to know how UITableViews and UICollectionViews are managed, including their dataSources. Especially, we need to know how arregloDeArreglos, modelOfSeason or any other data used for dataSource. here's the data Can you show the data as a JSON text? Which makes very, very easier to test your code. And please show the definition of your table view cell which is currently used.

With filling missing parts with simplified components, I could not reproduce the issue changes UI for every fifth cell. But could find one thing (in a limited context, similar to every fifth cell). You are not resetting the state of addToFavoritesButton: override func prepareForReuse() { self.goSafariButton.isHidden = false addToFavoritesButton.isEnabled = true addToFavoritesButton.setImage(SFSymbolsAsImg.plus, for: .normal) } I guess you need to add some info into your Tweet struct (or somewhere else but retrievable from Tweet) and set the state of addToFavoritesButton in set(with:user:) according to it. On top of that, animation does not finish. Alpha goes to 0, and then the image is being changed, alpha should go to 1 but never gets there. It stops somewhere between 0.7-0.8. Isn't it just a result of making the button disabled?         self.addToFavoritesButton.isEnabled = false Whether you use alpha-animation or not, disabled buttons show system image as if alpha being somewhere between 0.7-0.8.

Thanks for your kind offer, but I do not want to use sort of private things to exchange development info. If you can think of some other ways, please tell me. I will spend some time to fill the missing parts of the shown code until then.

When I attach the intended Launch image to the Main storyboard view it shows correctly,  but it shows black when I attach it to the Launch storyboard view.  Sorry, but can you be more specific and precise? Storyboard does not have a property view which you can attach image. So, what settings can cause a png to show black? To find what, you should better describe what you have done.

I mentioned why I changed those lines of code, it was to reduce the size of the shape drawn to see if it was bug in Xcode. As I wrote in my previous post, you need to change all the CGPoints consistently if you want to reduce the size. So, your code shown cannot be any sort of proof it was a bug of Xcode.
