Known issues

XAML Hot Reload doesn't work

We've identified a regression that prevents Hot Reload from working correctly.

The symptom is a yellow bar in Visual Studio that says:

XAML Hot Reload is disabled because your iOS Linker Settings for (project name) are unsupported. Set your Linker Behavior to "Don't Link" and rebuild your project to use Hot Reload.

The workaround is to do as the message says, or add this to the project file (which is the same thing):

<PropertyGroup>
	<MtouchLink>None</MtouchLink>
</PropertyGroup>

We've already fix this regression internally, and it will be shipped in the next service release.

New features

Multi targeting for library projects

We've added support for targeting the earliest APIs for a given .NET release in library projects, in addition to the latest APIs we support.

In this release, this means we support targeting our iOS 17.0 APIs + iOS 17.5 APIs.

Multi targeting is enabled by adding the given iOS version to the target framework in the project file, like this:

<PropertyGroup>
	<TargetFrameworks>net8.0-ios17.0;net8.0-ios17.5</TargetFrameworks>
</PropertyGroup>

Note that this will fail to build once we release support for iOS 17.6, stating that the iOS version 17.5 is not supported (since we only support earliest and latest - which would be iOS 17.0 and iOS 17.6 at this point). To avoid this, don't specify any version for the latest (because the default is the latest):

<PropertyGroup>
	<TargetFrameworks>net8.0-ios17.0;net8.0-ios</TargetFrameworks>
</PropertyGroup>

And this will target the iOS 17.0 bindings + the latest iOS 17.* bindings depending on the current release.

Note: the examples are for iOS, but this works for all platforms (tvOS, macOS and Mac Catalyst as well)

Bind protocols using default interface members

We've improved how we bind Objective-C protocols to take advantage of default interface members in C#: most importantly optional members are now members of the C# interface we map Objective-C protocols to (we previously used extension methods for optional members).

This has a couple of advantages:

• Makes it easier to implement optional protocol members, because Intellisense works in IDEs (since the members are available on the corresponding C# interface).
• Protocol properties can be implemented as actual properties, instead of a set of Get/Set pair of methods (which we had to do because there are no extension properties in C#, only extension methods).

• https://github.com/xamarin/xamarin-macios/blob/main/docs/objective-c-protocols.md

Versions

This release consists of the following versions:

• iOS: 17.5.8018
• tvOS: 17.5.8018
• macOS: 14.5.8018
• Mac Catalyst: 17.5.8018
