In debug configurations, fatal error messages include file & line number information. This update presents this information in a format matching the diagnostic conventions used by the compiler, which can be a slight productivity boost.
Code compiled with optimizations enabled (which is most production code) does not output this information, so it isn’t affected by this change.
Original format:
Fatal error: A suffusion of yellow: file calc.swift, line 5
New format:
calc.swift:5: Fatal error: A suffusion of yellow
