onNode can be null here, right? Is it safe to pass it into ApplyPropertiesVisitor.TryGetPropertyName?

we don't pass it to TryGetPropertyName. TryGetPropertyName is a child asking his mom "what's my name again?" and is used to find the property is set to. OTOH, onNode is the child of , and of type

if (onNode != null)
parentEnode.Properties[name] = onNode;
else

One thing I just noticed is that we add these attributes to the InitializeComponent() method:

[GeneratedCode("Microsoft.Maui.Controls.SourceGen", "1.0.0.0")]
[MemberNotNull("selfMediaElementView")]
[MemberNotNull("searchBar")]
private void InitializeComponent()
{

However, we are removing the initialization of some of these fields, for example the searchBar field in the Podcasts Header control. I'm not sure how to handle this though.... Thoughts?

this is generated by our SourceGen which is a different beast. but should indeed be fixed

@StephaneDelcroix is this one we can revive in .NET 7/MAUI?

Is there even anything left? Maybe just a merge conflict?

@jonathanpeppers we need to uplift the source generator to use the same parser as the compiler, so it can skip field generation for the x:Names that have been removed

* [ios] fix memory leak in GraphicsView (#16605)

Context: #16346

This addresses the memory leak discovered by:

    src/Core/src/Platform/iOS/PlatformTouchGraphicsView.cs(12,29): error MA0002: Member '_hoverGesture' could cause memory leaks in an NSObject subclass. Remove the member, store the value as a WeakReference, or add the [UnconditionalSuppressMessage("Memory", "MA0002")] attribute with a justification as to why the member will not leak.

I could reproduce a leak in `MemoryTests.cs`:

    ++[InlineData(typeof(GraphicsView))]
    public async Task HandlerDoesNotLeak(Type type)

Solved the problem by fixing two places:

* `PlatformTouchGraphicsView` now stores the `IGraphicsView` as a
  `WeakReference`.

* A `UIHoverGestureRecognizerProxy` is used for callbacks to the
  `UIHoverGestureRecognizer`.

* [ios] fix memory leak in SwipeItem (#16614)

Context: #16346

This addresses the memory leak discovered by:

    src/Core/src/Handlers/SwipeItemMenuItem/SwipeItemMenuItemHandler.iOS.cs(10,30): error MA0001: Event 'FrameChanged' could cause memory leaks in an NSObject subclass. Remove the event or add the [UnconditionalSuppressMessage("Memory", "MA0001")] attribute with a justification as to why the event will not leak.

I could reproduce the leak with a custom test in `SwipeViewTests`.

Solved the problem by introducing `SwipeItemButtonProxy` with the same
pattern from other PRs.

* [ios/catalyst] fix memory leak in DatePicker (#16589)

Context: #16346

This addresses the memory leak discovered by:

    src/Core/src/Platform/iOS/MauiDatePicker.cs(37,27): error MA0003: Subscribing to events with instance method 'OnValueChanged' could cause memory leaks in an NSObject subclass. Remove the subscription or convert the method to a static method.

I could reproduce a leak in `MemoryTests.cs`:

    ++[InlineData(typeof(DatePicker))]
    public async Task HandlerDoesNotLeak(Type type)

Solved the problem by fixing two places:

* `MauiDatePicker` now uses a `UIDatePickerProxy` type, for iOS

* `DatePickerHandler.MacCatalyst.cs` now uses a `UIDatePickerProxy` type,
  for MacCatalyst.

Other changes:

* Skip test on Android API 23

This is working for me locally on an API 23 emulator -- so I don't think
it is really leaking.

We skipped API 23 in another place:

https://github.com/dotnet/maui/blob/9fcccd57b5a3d664e4788b3c7fc3edc10010beaf/src/Controls/tests/DeviceTests/Elements/NavigationPage/NavigationPageTests.cs#L302-L303

We are more interested in iOS on this PR anyway.

* [build] Bump XCode to 14.31 (#16374)

* Add doc comments for common types used in templates, maps, webview (#16552)

* Add doc comments for common types used in templates, maps, webview
* Enable WarnigsAsErrors for inline docs on Maps

I went through every type/method/etc. used in the default MAUI app template and ensured there are doc for all of them.

I also added a few miscellaneous docs for WebView types and Map (many were copied from Xamarin.Forms docs).

Context: dotnet/maui#5611
Fixes: #239

The `net8.0` branch currently fails to build with:

    src/Mobile/Controls/Player.xaml.cs(54,9): error CS0103: The name 'podcastImage' does not exist in the current context
    src/Mobile/Controls/Player.xaml.cs(55,9): error CS0103: The name 'duration' does not exist in the current context

We think that `x:Name` in .NET 8 appropriately "skips" emitting fields
when used in combination with `<OnPlatform/>`.

We can condition the C# code accessing these files with `#if WINDOWS ||
MACCATALYST` to solve this.

There are also a lot places using `<On Platform="UWP, macOS">`, we could
consider cleaning these up in a future PR.

Lastly, use .NET 8 RC 2 released bits. We shouldn't need to be using nightly builds in this repo.
