Same issue here. It doesn't happen when building in the simulator. It happens when I am trying to archive the build.

I have the same exact issue. Doesn't seem like anybody cares about us...I believe it may be the webkit pdf display that is crashing and it may be because of memory. It works fine on the simulator but not the actual device for me. Does it do this on the simulator and the device or just the device?

Same here! Apple when are you going to look at this?
