There are a number of Canon cameras (like a 650D, 700D, 70D, EOS M/M2) which have an excellent touch screen interface.

 

An iPhone is nice for a phone. Not for a serious camera. Phones never will close the gap to big sensor cameras. If one is content with a phone camera, one never needed a DSLR in the 1st place. Not every driver needs a race car, not every snapshooter needs a serious camera.

 

As for swivel screens, they can break off, and serious weather sealing will be an extra challenge.  It is all about priorities and compromise.

You're taking my comment out of context. I never said an iPhone was a serious camera. Go back and read my comment. I said if Apple ever got seriously into the photography business they would destroy Canon and Nikon in a short time. If Apple released a full frame DSLR they would destroy the competition.
