I’ve lost count of how many times I’ve seen someone ask, “What should I use, SwiftUI or UIKit” or read a blog post titled “Is SwiftUI ready for production?” over the last few years. To be clear, I intend no criticism to anyone who asks those questions. It’s perfectly natural to want an answer!

Humans love to look for absolutes. We want to know that X is better than Y, so we don’t need to spend more time thinking about the subject again. We know that X is better. We can move on. It’s very pleasing to us.

Even though Apple’s message was clearer than ever this year, I still feel like you could replace that “is” at the start of the second line with “will be” or “might be”, though. 😅 Again, I don’t want to criticise this slide. It’s good to have a crystal clear message like this in a high-level session like the SotU.

So when I was reading Becky Hansmeyer’s recap of WWDC this week, the quote from Taylor Kelly that she pulled from the SwiftUI digital lounge was so refreshing to read:

Across all platforms, we’d recommend comparing your needs to what SwiftUI provides (so no hard rules/recommendations) — and keeping in mind that you can adopt SwiftUI incrementally.

Within Apple’s own apps on macOS, we’re ourselves using the full spectrum of approaches. From just a specific view/views in an app, e.g. in Mail, iWork, Keychain Access; to an entire portion of the UI or a new feature, e.g. in Notes, Photos, Xcode; and all the way to the majority of an application, e.g. Control Center, Font Book, System Settings.

But in the end, I’d recommend starting with a part you’re comfortable with and building up from there! You should look at SwiftUI as another tool in your toolset in enabling you to build the best apps you can.

First of all, what a lovely, genuine, honest answer. It’s not written for the press, and while I’m sure Taylor knew that what he wrote there was effectively public, I’m sure he’ll be surprised to see Becky quote it and me repeat it.

It’s worth repeating, though, because it concisely sums up not only the situation with SwiftUI but the situation with any tech both now and in the future. I’ve repeatedly written my thoughts on “purity” in technology, which is closely related.

I’m not waiting or even hoping for a “clean slate” where the answer is as simple as the SotU slide makes it seem, and I’m happier for it.

And finally...

Have you seen the leaked slide from WWDC '23 that shows off the next Apple silicon chip? 😂
