I actually figured out the issue! I just needed to find the app-specific path to the xml file first.

With a lot of help from your tutorials, I’m making an iPad app that takes video from the front cam and for each frame, detects a face and recognizes emotion. I’ve found that the app runs really slowly and sometimes crashes, though (I can get about 2 frames every 30 seconds).

Any ideas on what could be slowing it down and how to improve performance?
