This was also the case under ios 11.1 release version and now still on 11.2 beta. Why don't fix this? My app keeps crashing.
I know someone proposed to use a workaround to use style
writableCalendarsOnly instead of allCalendars, but that is no option for my app.Already a lot of my users are getting an Exception on opening the calendar chooser:
EventKitUI: -[EKUISemiConstantCache birthdayImageForFont:withColor:] + 392
Apple, when are you going to fix this production problem? Anybody knows a usable workaround?
