The recent survey I did reminded me that, when you work with Swift every day, it can be easy to see only its complexities.

A friend took delivery of one of the new M4 Mac mini machines this week, and I was curious how its performance would stack up against my 2021 M1 Max MacBook. I thought that building the Swift Package Index source code would be a reasonable real-world test. At least that's my real world! He's not a developer, though, so he wouldn't have Xcode or other developer tools immediately available.

It made me think about the bare minimum amount of software that is necessary to get a Swift project up and running. The instructions I needed were so simple: install Xcode from the App Store, paste a git checkout command into a terminal, open the package manifest, and build. That's quite remarkable, especially when you compare it to other software development environments¹.

It gets better if you want to do more than a speed test, too. Have someone download and install Swift Playgrounds and they'll be writing Swift within minutes. You won't need to know about Swift concurrency, generics, macros, or any other advanced language features. Upgrade that environment to Xcode and look at some SwiftUI code. It's clear and readable.

Anyway, I thought I'd remind you all, as I reminded myself, that it could all be so much worse. It reminded me to take a more optimistic view of things, and I thought that was worth sharing.

Oh, and if you're interested, the result of the speed testing was that the base spec of the M4 machine was about 30-35% faster than my M1 Max. Did I manage to keep my optimistic mood when I discovered that? Only just! 😂

¹ The only other environment I could think of that's this simple to set up would be C# development on Windows. The advantage in both cases is, of course, being the operating system vendor, but it's still impressive.

SwiftUI Self-Sizing Flow Layouts

What a great article from Keith Harrison on self-sizing flow layouts. I can hear you asking, “What’s a self-sizing flow layout?” Think about a grid that sizes and adjusts its layout as its content grows. For example, if each cell had dynamic type in it and you wanted to grow the cells rather than clip.

A Complete Guide to Implementing Live Activities

It’s been a couple of years since Apple added Live Activities to iOS, but they’re still quite rare to see in apps. Part of that is that they only suit certain types of apps, but is the other part that people don't know exactly how to implement them? Radhika Saliya has a great guide on getting one up and running.
