Here are some interesting thoughts on the idea that SwiftUI lets you choose you own architecture, unlike UIKit, which steers you towards some variation of MVC.
I also like their basic hand-drawn visual. 🤓

Xcode 12 is adding a new metric to objectively track how smoothly your app scrolls. This is kind of cool since scrolling smoothness feels right and is a sign of a good design.

I really like the points made in this article about Swift error handling: using throw/try/catch is actually much better than returning optionals or the new Result type.
👉Benefits of using throwing functions (try) – Swift’s most underrated feature?
Throwing errors, when used throughout your codebase, helps you reduce and simplify code. It makes your unit testing easier too.
As a former Java programmer, I have to admit some hesitance to throw anything. Java error handling can turn into a nightmare of its own.
But the author makes some compelling arguments why throwing might make sense in Swift. Error handling is never fun; let’s do it the easy way. 🤷🏻♂️
In a related note, Re: Making Wrong Code Look Wrong also talks about the benefits of throwing in Swift, in particular with relation to local reasoning. 👍

I like the title of this article because it recognizes that pulling third-party dependencies into your app has a cost.
👉 What Adding Dependencies Will Do To Your App in 2020
And yet we all do it because it also has its benefits. 🤦🏻♂️😂
That article is a realistic and practical look how the dependencies affect your app in terms of app launch times, app size, and build times. It compares Swift Package Manager 🤓, Carthage 🤷🏻♂️, CocoaPods 😬, manual dependency management 🥺, and Git Submodules 🤮.
I still have a dream of zero dependencies 🤩, but I know it’s not realistic in a complex app. 😑
