Thanks. Don't worry, we all have started as Swift beginners.

Effectively, State var are for this: save state…

That's true. But if the action is really (badly) destructive, a full fledged confirmation dialog may be useful (we know in some cases we do things mechanically).

Is there a single collectionView (newsCollectionView) in your class ? Could you show the code for HeadlineNewsCollectionViewCell ? Interesting discussion here: https://stackoverflow.com/questions/17729582/uicollectionview-in-a-uicollectionviewcell

szymczyk is right. These are 2 different things: learning XCode and Storyboards, which is quite independant of the language. And learning objective C. Do I guess well that you already know objC ? If so, use an Apple tutorial (App development with Swift for instance) but code everything in ObjC instead of Swift. That should be fairly easy.

What I described is how to use RECENT versions of XCode, not old ones. What didn't work? I do this frequently when I need to work on an old project.

Thanks for the feedback. Don't forget to close the thread.

Where do you get the error ?

I tried also, with 2 difference series of events, no avail. Just as if it lost the "memory" of the first click and just restarted a new activation cycle.

Additional comment as rule of thumb. You use for loop when you know in advance how many iterations: either because you write explicitly (0...9) or because the number is defined (for item in myArray). You use repeat … while or while when the number of iterations depend on condition that you don't know when you write code, such as while i < someValue where someValue is dynamic value that will change during code execution.

My question was probably not clear enough. What do you swipe to Desktop 2 ?

I tested on a project created with Swift2 ! And managed to update it directly in Xcode 13ß4 with the process I described in the link above. I had however a problem to open storyboard (kept spinning). I closed project, opened in Xcode 12. I was asked to select a device for IB. Did it, quit XCode12 and reopened in Xcode 13 without problem. I had also to recreate all IBActions connections which were visibly corrupted.

Evolutions on the forum are pretty slow effectively. We waited for years to post images. As for the silence, remember there are tens of millions of FB. I imagine it's hard to reply to each individually. For checking answers to my own posts, I pinned the profile page - https://developer.apple.com/forums/profile/Nickkk - and so I can immediately see if there's a new answer.

What are the identifiers of those CollectionViews ? Check carefully in all your project for those identifiers, maybe you have some mess up somewhere.
