Visual Studio 2017 15.6.4
Just upgraded to macOS 10.13.14 and Xcode 9.3
After this I'm not able to run any iOS applications on either simulator or a device.
Having selected an iOS project, Debug, and iPhoneSimulator as the configuration, the list of devices does not include any simulators - simply the Simulator placeholder. Trying to execute the project gives "Please select a valid device before running the application".
After selecting a real device and trying to execute I get the following error:
Launch failed. The app 'myapp.iOS' could not be launched on 'John's iPhone'. Error: error HE0003: Could not load the framework 'DADocSetAccess' (path: /Applications/Xcode.app/Contents/SharedFrameworks/DADocSetAccess.framework/DADocSetAccess): not found.. Please check the logs for more details.
Not sure if these two are related but it looks like Xcode 9.3 completely breaks the ability to run applications under VS2017.
