Updated Xcode this morning and now ionic project wont deploy to a device.
ionic run ios --device
Returns:
** BUILD SUCCEEDE
Linked in the Jenkins issue that matson kepson mentioned here there was a guy who attempted a PR to fix the issue. There was some unfinished change requests in his PR and I also found a few null ptrs in his changes. I forked his pr and fixed these things here and there is now a snapshot linked here that you can download and become unblocked until such a change is merged into the full build.
