THIS WEEK'S BLOG POST

​Swift 6: What’s New and How to Migrate​

The release of Swift 6 caused quite some discussion for those migrating their projects. I've seen several conference talks with slides showing hundreds of warnings and compiler errors after initially switching to Swift 6 language mode.

It's time to help you get started with the migration after sharing background info and, most importantly, new features of this significant language version release.

That's not all: I've also started working on a dedicated Swift 6 & Concurrency course.

QUESTION OF THE WEEK

“
When do you know a view is too complex and should be split to keep logic separate?
— Danijela

You start a new SwiftUI View and it all looks good. A few more features, view elements, and buttons are added along the way. Two weeks later, your component is suddenly covering 400+ lines of code.

It's a debate many teams have when defining their SwiftFormat or SwiftLint configuration files. Should we throw a warning when a file becomes too long?

It's subjective to say a view is too complex or a file is too long. What I can say is that any component benefits from seperation of concern. If I ask you: "What is the single thing this view does?" and you find it difficult to answer with just one thing, you know there's a potential to split things up.

I sometimes feel bad to have a really small view component, but I always remind myself that this view might be a small seed that will slowly grow. Preparing your code for the future means looking ahead and make decisions early in the process.
