I've noticed that the crash reports Apple collects aren't plentiful
enough. At first I thought this was because I was writing rock-solid
apps. Eventually I realized that only a small number of iOS users
have opted-in to crash reporting via iTunes; additionally they have to
sync with iTunes for the crash reports to be uploaded. I'm using a
crash reporting library now and have already seen some strange (and
exceedingly rare, thankfully) crashes. So far, it appears just under
1% of Meetings users are experiencing crashes. I'm researching fixes
but am having a lot of trouble reproducing the issue.
