Have a look here to understand how to mix Swift and objC: h t t p s : / / developer.apple.com/documentation/swift/imported_c_and_objective-c_apis/importing_objective-c_into_swift  or this one for some code samples   https://medium.com/@JoyceMatos/mix-and-match-objective-c-and-swift-c6bceb7f81f3

Did you try with Xcode 13.2 RC ?

Yes, your app would probably be rejected. Don't forget to close the thread. And wish you can find an alternative.

Yes there is an API to remove constraints on a view. See options here https://stackoverflow.com/questions/24418884/remove-all-constraints-affecting-a-uiview

Yes, I understood. But you do not answer my question : what happens with a different type of animation, not curl ?

Did it answer your question ? If not, please explain. If yes, please close the thread on the correct answer.

From eskimo answer, I understand there's no chance to file an enhancement request. And don't you know the author ? Or the approximate date of publish ? If you search keychain, by Newest order, you can go directly (in URL) to page 100, which lists posts about 2 years old. You can search older. A lesson here. When including such link in your doc, it may be safe to save content in pdf somewhere (I do this for all importants posts I find in forums).

So, do it.

It is just impossible to understand your question. Same level as what ???

I understand you have problems, trying to develop with SwiftUI. Mastering the concepts of SwiftUI do require some serious learning, before engaging in a real app development. If you did not go through this learning (with free Apple tutorials for instance), I would advise you to do so. And start designing your app once done. That will save you a lot of frustration and headaches. Good luck.      And also, when you post code, tell exactly where you get the error message such as '“Missing Parameter for accountBackEnd…”'

Valuable explanation, thanks. Would be a useful complement to 'isKeyWindow' documentation.

I tested both with vertical and horizontal scroll. Still works fine in iOS 15.2 simulator. Tested as well with iOS 15.0 simulator (Xcode 13.1). No problem either, collections scroll independantly.

A correction on the last code posted. Before adding collection as subview to the cell, one need to remove previous subviews (the already created collection) ; add the following before cell.contentView.addSubview(collectionView)                                                                                                               for v in cell.contentView.subviews { v.removeFromSuperview()  }

I tested on iOS 15.2, no issue. Tested also with higher CollectionViews, exceeding the height of tableView cell. No issue either.

I sent you a mail at p…t @ g m a i l .c o m . I send again. Check in your spam.
