I think I have been encountering a bug in the collectionview tutorial below
I am running swift 10.1 and when I get to Step 2: Implementing the CollectionViewLayout Core Process,
following the instructions of pasting the text into ViewControllerLayout.swift, I get an error where prepareCache is not recognised. See the screenshot below.
This is the full set of warnings that pop up in the warnings side-bar
I have tried re-starting the tutorial, and pasting within various levels of the curly braces of the above prepare function, but to no avail. Is there something obvious that I am doing wrong? I would really like to get on top of the parallax effect, but this bug has been puzzling me for several evenings.
There was a tutorial topic with some messages moderated by @shogunkaramazov, however, the tutorial thread has been closed for some time now
