I did not expect someone to actually respond, none the less in such an educational and constructrual manner. Thank you for the references and articles. I've been going through Paul Hudson's course works and I haven't come across him actually talking about this outside of the linked article which seems relatively new compared to everything else.

Again, thank you!

Yes this is possible. It is mentioned in Swift Documentation. See the 1st link below.

As far as I know, there is no official code style guide provided by Apple so I can't tell you for sure whether it is standard or best practice. According to above mentioned documenation it is opportunity rather than obligation.

Just my experience:

• I've been taught to omit "return" in one-liners at the iOS course
• Paul Hudson and John Sundell has similar articles about it, but they say "you can omit..."

I think this is the subject for regulation in particular company.

• https://www.swiftbysundell.com/tips/omitting-the-return-keyword/
• https://www.hackingwithswift.com/quick-start/understanding-swift/when-is-the-return-keyword-not-needed-in-a-swift-function

1. Didn't know you you had the choice to no use the "return" keyword for one-liners.
2. Is this actually considered standard or best practice?
