Preview: Xcode 9.3 beta 4, iOS 11.3, macOS 10.13.4 Support – Preview 2

Today we are releasing the following builds as Xcode 9.3 Web Preview 2. These versions include preview Xamarin SDK bindings and preview IDE compatibility for Apple’s Xcode 9.3 beta 4 release.

Note that these are  standalone download links that are not yet published in the Visual Studio for Mac updater channels. As a result, Visual Studio for Mac will offer an “update” back to the current published updater channel versions when you have these versions installed. You will need to disregard that notification if you wish to keep using this Xcode 9.3 support preview. The Xcode 9.3 features will be added to the updater channels in the future, after Apple publishes the first non-preview version of Xcode 9.3 to the App Store.

Any bug reports about these preview Xamarin bindings are much appreciated!

Installing on Mac

  1. Ensure you are up-to-date with the current Visual Studio for Mac Stable updater channel versions.
  2. Ensure you have the Xcode 9.3 beta 2 version installed from Apple. You can optionally install this beta version alongside your non-beta Xcode.
  3. Download the Xamarin.iOS installer .pkg file and run it.
  4. Download the Visual Studio for Mac .dmg file, open it, and copy the .app bundle to a desired install location. For example, you can optionally add this preview version alongside the Stable version of Visual Studio for Mac by copying the .app bundle to a temporary location, renaming it, and then copying it to your Applications directory.

Uninstall steps

Navigate to Visual Studio > Check for Updates, and install the current Xamarin.iOS and Visual Studio for Mac versions from the Stable updater channel.


Installing IDE compatibility for Visual Studio 2017 version 15.6

  1. Ensure that Visual Studio 2017 is up-to-date at version 15.6 and has the Mobile development with .NET workload installed.
  2. Download the combined IDE compatibility .vsix file. If your web browser saves the file with a .zip extension, rename it back to .vsix after download.
  3. Double-click the .vsix file to launch the VSIX Installer.
  4. Be sure to select only your non-preview instance of Visual Studio 2017 when prompted. (This .vsix package is based on the Xamarin 15.6 release, so it is not fully compatible with Visual Studio 2017 version 15.7 Preview.)
  5. Click Install, and wait for the VSIX Installer to download and install the components.

Uninstall steps

If you wish to switch back from the Xcode 9.3 beta support previews to the default Xamarin versions bundled in Visual Studio 2017 version 15.6:

  1. Navigate to Tools > Extensions and Updates >  Installed.
  2. Locate the Visual Studio Tools for Xamarin (Alpha) item.
  3. Click the Uninstall button.
  4. Close Visual Studio 2017 to allow the VSIX Installer to launch and complete the uninstall process.
