Comment on attachment 279530 [details] Proposed patch View in context: https://bugs.webkit.org/attachment.cgi?id=279530&action=review > Tools/Scripts/webkitpy/xcode/simulator.py:286 > + _log.warn("Error in checking Simulator boot status.") This message will be fairly confusing in the logs, because it's unclear what the consequence is. I would add "Will retry in 1 second." after this.
