[BUG] [iOS] CollectioView hosted in PopupV2 doesn't select an item unless you hold a row for longer than 4 second

[MichaelShapiro]

Is there an existing issue for this?

• I have searched the existing issues

Did you read the "Reporting a bug" section on Contributing file?

• I have read the "Reporting a bug" section on Contributing file: https://github.com/CommunityToolkit/Maui/blob/main/CONTRIBUTING.md#reporting-a-bug

Current Behavior

CollectionView hosted inside the PopupV2 doesn't acknowledge item selection tap unless you tap and hold the row for more than 4 seconds. Android works fine. I tested with "old" CollectionView and with CV2 -the same behavior. Video is attached.

Expected Behavior

Tapping on a CollectionView with SelectionMode="Multiple" or "Single" must actually select the tapped item (same as on Android as shown in the attached video)

Steps To Reproduce

Follow the repository link, run the project "PopupV2Bugs", tap the button "CV2 selection bug"

---

Host a CollectionView inside the PopupV2
Populate CollectionView with some data
Set SelectionMode="Multiple" (or "Single")
Show popup
on iOS device - Tap any item in the CollectionView

Expected result:

• item remains selected (highlighted)
• SelectionChanged event fires

Actual:

• item remains unselected
• SelectionChanged doesn't fie
• only when you hold an item for longer than 4 seconds the above two actions happen

Anything else?

Again, I have tested with "old" CollectionView and with the new version - CV2. Result is the same: iOS doesn't immediately select the tapped item... unless you tap and hold for 4 seconds.

As far as why I need a CollectionView insidea popup - I have a need to present a list of dates in the popup for the user to make a selection. Here is the example of a working popup (before I updated tp V2)

Might be a duplicate of #2730

That would be funny because I created 2730 :)
Do you mean that the root cause might be the same?

[bijington]

I don't think it is a duplicate because on first glance I see that CanDismiss... (that's hard to type on a phone) is set to false in this scenario

[MichaelShapiro]

Yes, I have tried this example with CanDismiss True and False - the result is always the same: I have to hold the row for longer than 4 seconds for it to get selected :( That is, unfortunately, a hard stop for me now on transitioning to this new popup and upgrading to this latest version of toolkit. I really hope and appreciate if it can be prioritized soon, please.

I take it back I think it is caused by related functionality. I believe this PR solves the bug #2741
