Don't hesitate to open new thread each time you encounter a new roadblock (when you cannot manage to solve by yourself). That's a very efficient way to learn.

You should file a bug report. And describe as precisely as you can your configuration (I do not get it, probably because of differences between our confs).

umbrella is a c keyword, to announce a series of import statements.

I probably miss something here. If you hit the bell on the thread, don't you receive a mail when an answer is posted ? I did this on some of my questions and did receive a notification.

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

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.

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.

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

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.

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.

Where do you get the error ?

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

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.
