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://docs.swift.org/swift-book/LanguageGuide/Functions.html
• https://www.swiftbysundell.com/questions/when-can-the-return-keyword-be-omitted/
• 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?

Hi,

Keep in mind that for easy kata, the best approach is rather along the line of do one thing and do it well. Which is the opposite of what you're asking for here:

For example:

• the use of the class. But why in the first place? There is no point to use a class with the current context because there is no state to keep and nothing doable with it (hence: a class without methods is generally a bad idea)
• the overall task: what's the interest of the result? Any application?
• the identifier of a class is supposed to be in PascalCase, in python

May I remind you that you're not supposed to use CW to build challenges for your students?

cheers

ok 😒

You should or else it will get retired soon (few hours later) and it will be in your profile forever ~~ :)

Community?

Ohh, sorry 😔
Should I remove it or not? 🤔

? 😅

Nice emoji, but

• @test.it("Fixed Tests") && @test.it("Random Tests") should be used instead
• The user can modify the input

And the issues below as well ~~ (You should read --> test framework && authoring) (Or more info regarding the docs which is just on the left sidebar of CW ~~)
