I thought I’d note that I just ran into a specialized failure on the new iOS 7.1.1 running on hardware. I should note that the following bug does not appear on any other version of iOs, yet I have not been able to find the iOs7.1.1 simulator so I haven’t tested it there.
It’s the typical failure when reflection is not able to find your reader; I ran into this years ago when this area was still being worked on and was delighted to see it fixed now.
I’m digging into this now, but I thought I would raise the issue in case anyone else was investigating the same.
