Thanks for the simple and clear explanations!

Glad it was helpful!

Thanks! I don't like the implicit returns nor the explicit lifetime management, but the macros will be powerful. Good explanations!

[@SwiftBird]

Thank you! I’m currently working on the “macros deep dive” video. It’ll be out in the coming days-hopefully 🤞🏻

[@ivanshevy]

Good luck!

Swift has a beginner friendly learning curve, but the curve extends infinitely just to learn all the features

[@SwiftBird]

You’re right! But also, you don’t need to know *every* feature to be proficient. I like Swift because you can learn new tricks (and forget the old ones) as your tasks change-and still feel confident regardless.
For example, I learned about the for-case-let-in loops just a week ago, and though they look clever and make the code shorter (e.g. you can run the loop’s body on just the non-optional elements), they’re such a nuanced feature it’s not worth the cognitive burden, IMO. I was totally fine not knowing about them for the past six years 😅

Hey, are all previous swift features lost where produce new once. thank you.

[@SwiftBird]

Hi! No, of course not. Minor Swift versions (5.8, 5.9, etc.) don’t remove any previously-added features, though they can change the way those features work. But normally, you can use everything from every previous release.

Interesting comparison, thanks!
