Xamarin.Mac 6.0 Release Notes

System Requirements | What's New | Known Issues | Blogs | Open Source

To see installation instructions for both Visual Studio for Mac and Visual Studio 2019, please visit https://docs.microsoft.com/en-us/xamarin/get-started/installation

Requirements

  • The latest features and APIs require Xcode 11 and the bundled iOS, tvOS and watchOS SDKs
  • Apple Xcode 11 requires a Mac running macOS 10.14.4 (Mojave) or newer
  • Visual Studio 2019 or Visual Studio for Mac

What's New in this Release

  • Apple has removed support for executing 32bit applications in macOS 10.15 Catalina. See our blog post to see how this can affect your applications when using Xamarin.Mac 6.0 (or later).

Support for Xcode 11

For more information you can consult the Xcode 11 release notes from Apple.

Support for macOS 10.15

See our API diff to browse the latest changes.

For more information you can consult the macOS 10.15 release notes from Apple.

Support for uploading Mac Applications to iTunes Connect

Starting with Xcode 11, Apple stopped distributing Application Loader, which was used to publish Applications to the iTunes Connect website.

We updated our MSBuild tasks to make use of a new tool shipped with Xcode: altool.

This is a necessary step for the IDEs to continue providing the ability to publish Applications to the App Store.
