Is it possible to debug “Terminated due to memory error”?

Question

In a certain (consistent) point when my app is running, I consistently get the xcode error message

Terminated due to memory error.

Answer 1

I was using Tesseract for OCR and when my target text got scanned, a GIF was supposed to play. When the GIF started to play, there was a memory spike, from 70-80MB to 450MB. The problem was that GIF was taking too much memory, the app would crash and Xcode would show that message. So I removed the concerned imageView from the superview of the ViewController.

imageView.removeFromSuperview

After this, the app would still spike to 450MB but then immediately release and come down to 40MB
