Investigate better error reporting in CLI when xcodebuild fails #557
Description
Describe the feature
Better error reporting when run:ios or build:ios fails
Motivation
When xcodebuild fails, it's hard to navigate to the source of error. Some errors are not even surfaced unless ran with Xcode directly. Investigate the source of the issue and possible mitigations - maybe there are flags we can use, or log files we could crawl for better insights.
