Hi,

Sorry if this has been asked before, I’m a total newbie. I’m going through the MyLocations iOS Apprentice Book when I noticed on page 264, that there are times when setting colors we are using ‘UIColor.black’ and sometimes we are just using ‘.black’. Are these interchangeable?

In this context, I think they’re interchangeable. The fields you’re setting (e.g. `tableView.backgroundColor`) are known to be of type `UIColor`, so Swift can infer that `.black` is short for `UIColor.black`.

In other contexts, Swift might not able to infer a type so easily, so you’ll need to be explicit and type `UIColor` in.
