Auto Layout issues - red lines

[shreya]

So I’m using xcode version 9.4.1 and following the AutoLayout section of the Quiz app. I have followed the instruction to the letter and still getting “missing constraints” error and red lines all over. I cant seem to figure out what I am missing as this is my first exercise on Auto Layouts and I have followed all instructions. I’m wondering if it has something to do with the new xcode version.

This is how i setup the constraints for the bottom three objects on the view. The Update Frames option seems to have been removed and I think xcode is automatically doing the task. Pls correct me if I am missing something.
