Is clicking on a link to document of type text/calendar believed to work on iOS? Using https:, not webcal:, that is, "event attachment", not "dynamic calendar subscription".
If so, do you have an example of one that works?
Because mine appear not to. Mostly Safari just does nothing, but sometimes it pops up a dialog saying "Download Failed, Safari cannot download this file."
Related question: if Safari was logging an error to syslog on my phone, how would I see it? If it's in "Xcode / Window / Devices / Device / View Device Logs", I don't see it. That seems to only be crash logs, not general syslog verbosity.
