I don't see a yellow sign in front of the VC, but but a red arrow at the right side of the VC. When I select it, I see the list of all the errors. I take the first one in the list from the top, which belongs to cell 16 (numbered from top to bottom). It says "Missing constraints". So I select "Add missing constraints" and all of a sudden, 6 of 10 warnings are gone. Checking which contraints were added, I see that nothing (!) changed to my constraints. Hence Xcode didn't change anything, but decided to cancel 6 warnings.
Besides this, please look at my example above (the Reset settings button). This one is pretty simple and there is virtually no room for mistakes (= wrong/bad constraints set by user).
Ignoring warnings was what I did until now, but that's at the very best a workaround, no solution. I'd like to find the reason for these warnings.
