I have been getting the below error and none of the existing Stack Overflow answers helped. I am poor at finding the exact location where error is formed by looking console results.
This is the error I get when I run in older devices (works fine in newer devices). What things can I try to determine the problem?

I had the same issue (using Xcode11 and running iOS 10.3.1). Unchecking Content Layout Guides from the Scroll View worked for me.
