Access image EXIF info on mobile

Didn't bother to test on Android since mergAV isn't supported, but I  
can confirm the crashes on simulated devices. When tested on physical  
devices, the stack never crashed but didn't always work depending on  
the source of the image. Even images from the same device didn't  
always work, which makes me think there was a change somewhere in how  
Apple wrapped the metadata. For instance: photo taken today didn't  
show EXIF, but photo taken on same phone 6 months ago does (don't  
remember what OS that would have been, but almost certain it was  
different from current version).

I updated your bug report with my findings from 2 real and 2 simulated  
devices using your test stack. One caveat is my simulated devices run  
10.2 but my physical devices are running 11.x
