[iOS/Catalyst] Swipeviews with invoked properties crash the app in Release

[arnaudaug]

Description

Hello MAUI Team,

I am encountering a problem with swipeviews containing invoked properties.
I would like to point out that these are crashes on generic pages when the application is compiled in release mode on iOS or MacCatalyst and that it works well in Debug.
It also works fine in Debug/Release on Android.

Regards

Steps to Reproduce

1./ Copy my repository
2./ Compile the application in release mode (provisioning profile needed and must be selected).
3./ Run the app with your iOS device.

First button : Generic listpage with one Invoked event = Crash after swipe + press "Delete" on an item.
Second button : Generic listpage with many Invoked events = Crash after pressing the button. We should display a page with two swipes on the left to move up and down an item and one swipe on the right to delete it.
Third button : Classic page with Invoked event : Works well.

I use BasePage for generics models.

In 8.0 RC2 : Crash according to the cases I identified
In 8.0 RC1 : Known bug, invokeds do not react.

If you need clarification, don't hesitate.
Thank

Hello @jsuarezruiz and @Eilon ,

I updated the versions :
MAUI : 8.0.0-rc.2.9511
Xcode 15.0.1
iOS 16.7.2 (I don't want to update to iOS 17 yet)
macOS Ventura 13.6.1 (I don't want to update to Sonoma yet)

I tested this morning and I still have the same problem on an iOS application in realize mode. :(

Have you been able to make progress in identifying the problem (perhaps in the overly optimized compilation)?

Thank you for helping me

I have the same issue, it seem like when using custom event handler it crash the application, on Android (Debug/Release) IOS (Debug), Windows are fine but IOS release crash

        <DataTemplate x:Key="HomeItemTemplate" x:DataType="app:AnnouncementsPageItemModel">
            <app:AnnouncementItemContentView AnnouncementTapped="AnnouncementItemContentView_AnnouncementTapped" ComponentData="{x:Binding}" />
        </DataTemplate>

namespace LBA4;

public partial class AnnouncementItemContentView : ContentView
{

    #region [ Delegates ]


    public delegate void AnnouncementTappedEventHandler(string fileUrl);
    #endregion

    #region [ CTors ]

    public AnnouncementItemContentView()
    {
        InitializeComponent();
    }
    #endregion

    #region [ Properties ]

    public static readonly BindableProperty ComponentDataProperty = BindableProperty.Create(
            nameof(ComponentData),
            typeof(AnnouncementsPageItemModel),
            typeof(AnnouncementItemContentView),
            default(AnnouncementsPageItemModel)
     );
    public AnnouncementsPageItemModel ComponentData
    {
        get => (AnnouncementsPageItemModel)GetValue(ComponentDataProperty);
        set => SetValue(ComponentDataProperty, value);
    }

    #endregion

    #region [ Events ]

    public event AnnouncementTappedEventHandler AnnouncementTapped;

    private void ViewFile_Clicked(object sender, EventArgs e)
    {
        this.AnnouncementTapped?.Invoke(ComponentData.FileUrl);
    }
    #endregion

}
