Known issues

VSCode on macOS 15.0 (Sequoia)

VSCode currently has some incompatibilities on macOS 15.0 (Sequoia). Full details (with workarounds) can be found here: microsoft/vscode-dotnettools#1449

The native strip tool might crash (and exit with exit code 139)

This is a bug in the native strip tool (shipped by Apple with Xcode).

The simplest workaround is to disable stripping by adding the following to your csproj (the downside is that the app size will increase somewhat):

<PropertyGroup>
    <NoSymbolStrip Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'ios'">True</NoSymbolStrip>
</PropertyGroup>

For more information: #19157

App submission denied because app references the BrowserEngineKit framework

The workaround is to add the following to the project file:

<Target Name="DoNotLinkWithBrowserEngineKit" AfterTargets="_ComputeLinkNativeExecutableInputs">
	<ItemGroup>
		<_NativeExecutableFrameworks Remove="BrowserEngineKit" />
	</ItemGroup>
</Target>

For more information: #21324

Binding projects don't build

Binding projects will fail to build with an error like this:

/usr/local/share/dotnet/packs/Microsoft.iOS.Sdk.net9.0_18.0/18.0.9600-net9-rc2/tools/msbuild/iOS/Xamarin.Shared.targets(1776,3): error MSB6006: "dotnet" exited with code 150.

It might be possible to work around this by installing a daily .NET 9 RTM build from here: https://github.com/dotnet/sdk/blob/main/documentation/package-table.md
