I came across this article from Krzysztof Siejkowski when he released this new obfuscater. I'm not a big believer in the need for obfuscation, but this article explaining how he built it is fascinating and definitely worth a read.
I'm not a big fan of customising alert views. It's usually a better idea to implement a new view controller and present it in some way, which doesn't always need to be full screen! There are instances where it's appropriate though and I think this customisation from Ole Begemann is a good example. It was also fun watching this project progress throughout the week.
I've mentioned bottom sheets a couple of times recently but always in the Design section, with no code in sight. I liked Simon Kågedal Reimer's article on the subject, especially how he dealt with the scrolling complexities.
Ben Dodson on this increasingly common use case now that Apple has adopted this kind of layout for a lot of "What's new" UI. Oh and before you even say it... No, you shouldn't just stick it in a web view! 😀
