Hmm, it does look like XCTest needs some work done to get things working with the latest Swift 3 changes made in the stdlib and corelibs-foundation. I don't have access to a development environment to investigate further, but as far as I can tell, this wouldn't build on Linux either. Has there been any indication of these issues from CI, I wonder?<div><br>On Friday, 1 July 2016, Madhu Samuel <<a href="mailto:madhusamuel@gmail.com">madhusamuel@gmail.com</a>> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>I just found more error details in the log.
