I’m very happy with iOS 12. It’s one of Apple’s best iOS releases in years. Part of the reason it worked out so well is that Apple didn’t bite off more than it could chew—nearly all of iOS 12’s features were available at launch, or came very quickly in an update. It’s a huge improvement over iOS 11’s problematic rollout. iOS 12 seems primarily geared at smoothing out long-standing pain points: we got a renewed focus on performance and reliability, grouped notifications, Screen Time, Group FaceTime, and better Maps.

But Apple can do more, much more. The latest iPhones and iPad Pros sport processors, cameras, and sensors that are capable of incredible things, but iOS at times feels like its holding us back. In particular, the iPad Pro feels like it has everything it needs to be a complete laptop replacement—except an operating system that lets you do everything you need to do on a laptop.

With that in mind, here are some of the things I hope to see in iOS 13.

Keep it fast, but drop support for the oldest devices

Apple’s focus on performance in iOS 12 made a huge difference to older iPhones and iPads. You won’t necessarily see it in benchmark app results, but in practice the difference is night and day. The keyboard and share menu springs right open where there used to be a short delay. Apps launch faster. Scrolling is smoother with fewer dropped frames. It’s not uncommon to hear iPhone 6s or iPad Air 2 owners say, “It’s like my phone is brand new again!”

Whatever changes Apple makes in iOS 13, it’s imperative that it keep performance every bit as fast and responsive as iOS 12.

I could understand if iOS 13 doesn’t support all the same devices as iOS 12, however. I might even welcome it. It’s impressive that you can run iOS 12 on everything going back to the iPhone 5s and iPad mini 2, but those devices have only 1GB of RAM. Cutting off the oldest devices would still allow Apple to support iPhones and iPads up to five years old, but lets it build iOS 13 with a minimum RAM requirement of 2GB. The features Apple can add with a higher minimum RAM spec are probably well worth the tradeoff.

Dark Mode

You know what Apple operating system has a dark mode? macOS Mojave. And now that a greater number of apps have added Dark Mode support, it’s pretty great.

Adding Dark Mode to iOS just makes sense, and not just because users have been clamoring for it for years. Apple is deep into a project to make it easy to port iOS apps to the Mac by adding support for UIKit—the iOS interface development framework— to macOS Mojave. At the start, Apple alone is using these tools to port a few iOS apps to macOS Mojave: News, Home, Voice Memos, and Stocks. Eventually, the tools will allow all developers to much more easily create macOS versions of their iOS apps.
