This feeling that “man dock.app is crashing more” followed by a few otool queries showing more Swift libraries gives me a vague suspicion that Swift rewrites have been leading to more end user noticeable crashes. I’d find it interesting to see some actual statistics on it in the form of “x crashes per 1 hour of program usage”. Perhaps it’d actually be lower than Obj-C but it doesn’t feel that way. Is it due to Swift error handling or just to rewrites? This would be an ideal time to get such statistics ! As it’s not often a giant platform starts switching to a new language and offer the chance to gather real stats rather than bikesheading or doing undergrad cohort experiments would be very interesting.
