tableView Cell gesture disabled, strange behavior Xcode 12 ios14

Hello, I observe something strange today, similar to this feedback: https://stackoverflow.com/questions/63987896/problem-with-gesture-in-xcode-12-and-ios-14

In my case we have an UICollectionView which contain an UiTableView.
My UITableViewCells will contain an UIView container, parent of the entire contents of the cell.

Code Block 
let container: UIView = {
        let v = UIView()
        v.translatesAutoresizingMaskIntoConstraints = false
        return v
}()
override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
        super.init(style: style, reuseIdentifier: reuseIdentifier)
        self.addSubview(container)
				...
        self.updateConstraintsIfNeeded()
}

Nothing really complex.

But since ios14 xCode 12 all my interactions contained in my container are disabled.

I then discovered the post above, which refers to the mandatory use of contentView now.

Code Block 
self.contentView.addSubview(container)

I have also observed that by simply doing this :

Code Block 
self.contentView.backgroundColor = .clear
self.addSubview(container)

without using the contentView, everything was fixed. Which makes me think of a bug.

My question is therefore the following, I have successfully migrated to using contentView, but is this a bug or
should we now use default contentView in a cell?

Thx for you time :)
