Unable to deploy Xamarin.iOS application on device using Xcode 9.3

After upgrading to XCode 9.3 (9E145), I can no longer use Xamarin and deploy to any of my iOS devices.

I run Visual Studio 2017 on a PC and use the Mac as a build agent. Before the upgrade, everything worked fine, but now I can no longer deploy applications.

I get an error with the missing 'DADocSetAccess' infrastructure:

The launch failed. Failed to start the application "iOSTest1" on "My iPhone". Error: Error HE0003: Failed to load the "DADocSetAccess" infrastructure (path: /Applications/Xcode.app/Contents/SharedFrameworks/DADocSetAccess.framework/DADocSetAccess): not found .. Please check the logs for more details. The application was interrupted.

I can confirm that the missing structure is missing on my Mac.

I also tried using Visual Studio on my Mac, but this fails with the same error. However, I created testapp in Xcode, and it worked just fine, so I suspect the error is related to Xamarin / XCode in some way.

I tried many hours to reinstall Xcode twice, but the problem still exists. It is also not possible to run on the simulator using VS2017, which also worked just fine before the Xcode 9.3 update.

I cannot understand what these frameworks are used for, since it is great for deploying and running applications from Xcode.

Does anyone else have this problem?

Any help is appreciated. Thanks

Sustainable channel now supports Xcode 9.3 (I was on the beta channel)

Switch to a stable channel or download the latest updates, and now it should work.

These are the versions that have the update:

  • Visual Studio for Mac 7.4.2.12
  • Visual Studio Tools for Xamarin 4.9.0.753
  • Xamarin.iOS 11.9.1.24
  • Xamarin Remoted iOS Simulator 1.2.4.12

You can now download xcode 9.2 before xamarin can handle xcode 9.3. You can download 9.2 at https://developer.apple.com/download/more/

Xamarin just fixed this problem. If you are using a Mac, just upgrade your VS for Mac. The fix for Windows VS will be in version 15.6.5, which is not yet available, but you can download and install the necessary package for Xamarin right now. Just follow the link below: https://releases.xamarin.com/service-release-15-6-5/

UPD: A fix for Windows is now available. Just download VS 15.6.5
