Description Ben Buttigieg 2017-08-29 16:28:12 UTC
I have a customer complaining about an issue where VS for Mac appears to be corrupting the xCode installation and renders xCode unable to be opened. 
He says he is having to reinstall XCode and replace Xamarin iOS framework a few times a day to keep working! 
My initial thought was that it was a hardware issue. Dodgy SSD or Harddisk. However it's happening on multiple machines including the build server.

The current thinking is it is due to something in the build process as it seems to happen after a successful build. Subsequent builds will then fail as the iOS sdk becomes unavailable and can only be fixed by reinstalling xCode and the iOS Sdk. This obviously is wasting a huge amount of time.

So I understand the idea but with no actionable data this is going to be hard to track and resolve.

Could we get full build logs, crash reports (if any), test case (to reproduce) and all version information.

To get full build logs just set the log verbosity to diagnostic at the following location: Preferences > Projects > Build.

Also since the current thinking is "it is due to something in the build process as it seems to happen after a successful build" I'm gonna assign that to iOS/msbuild but it could very well be a different part of the product.
