Today Microsoft has released a new version of Visual Studio to add support for Xcode 9.2

This is a FUNDAMENTAL update for Visual Studio and Xamarin as with the old version you cannot compile code for Apple (you can read the?article here).

Let’s see now the complete

Release notes:

  • VS 15.6 does not respect the ‘apply server settings to all users (store in project file)’.
  • Project could not be opened because Visual C# 2017 compiler was not created.
  • NuGet Package Manager only sees latest package versions after manually clearing cache.
  • Lost IIS Server Settings.
  • Visual Studio hangs during Nuget package update.
  • Installer throws unexpected error and saved changes to Solution2.sln are not saved.
  • C:\\Windows\\temp?fills up with .itrace files after upgrade to 15.5.6.
  • vstest.console.exe?fails test run with socket exception.
  • This release includes support for Xcode 9.3.

There are a couple of important issues fixed in this release but definitely the support for Xcode 9.3 is the most important feature of this update.

You can update Visual Studio going on Help -> Check for Updates or you can install Visual Studio from here:

UPDATE 4/4/2018: Microsoft has released the version 15.6.5 for Visual Studio that adds support for XCode 9.3. You can read more here.

The current Xamarin tool for Visual Studio 15.6.4 is not compatible yet with Xcode 9.3 so if you update Xcode to this version, you will not be able to compile your iOS projects anymore.

In case you are still using the Xcode version 9.2, disable the auto update.

If your mac has already updated Xcode to the new version 9.3 and you need to compile your projects for Apple, then you need to uninstall Xcode 9.3, disable the auto update and install Xcode version 9.2.

You can download Xcode version 9.2 from here:

Xamarin is already working on it but probably it will take some days.

I will update this post as soon as the issue will be solved.

Microsoft has released the version 15.6.3 of Visual Studio and it contains several fixes some of them for Xamarin.
