Should you write your app in SwiftUI?
Nick O'Neill nails the pros and cons of jumping in early on SwiftUI (and Combine). My opinion? I'd say it's not wise just yet if you make (or plan to make) a business of your app. For side projects, or brand new apps that aren't going to ship for a little while, go for it!
SwiftUI instant previews without Catalina
Want an interactive experience while working with SwiftUI, but still too nervous to put the Catalina beta on your development machine? John Holdsworth might have some good news for you.
Unused code cleanup in iOS projects
Maksym Shcheglov with a reminder that it can be easy to forget about the unused code that's hiding in the far reaches of your app. This guide on how to find it, and remove it is worth a read.
You might not think there's a lot to learn about SwiftUI animations, given that they are implicitly added by default. You'd be wrong. This excellent article from Javier Nigro may only be a "Part 1", but even so there's a huge amount of knowledge on how to tame animation in our newest UI framework in this post.
The Curious Case of the Core Data Crash
I always love a good debugging story. You'll almost always learn something, even if you don't have the same issue as the person doing the debugging. This time it's Sean Heber's turn to teach us something about iOS background execution.
Caching in Swift
The biggest performance win you can ever get for your app is to make it do less. One way to achieve that is to cache things once you've done them once! Let John Sundell take you through taming
Using GraphQL in iOS with Swift
Kristaps Grinbergs with a great post introducing GraphQL, then covering how to use it from Swift with the Apollo iOS GraphQL client. Worth a read.
NSJSONSerialization is probably fast enough for 99% of cases, and I'd recommend using it whenever possible. However, if you're often parsing a lot of JSON then the performance wins in this library from Michael Eisel might be what you need.
Of course, you've definitely made use of the techniques in John's post about Caching, and Kristap's post on GraphQL before getting to this point, right? 😬
Business and Marketing
When you are hurtling towards a release, it can often feel like shipping the binary is the finish line. Of course, it's just the beginning of a new phase of the app lifecycle, and Brent Simmons is here with some great pointers after the release of NetNewsWire. Congratulations to Brent (and everyone else involved) on the release! 🎉
As with every post on Curtis Herbert's blog, this is an exceptionally well thought out post about whether, how, and when to consider an Android version of your app.

I agree with John Gruber on the iOS 13/13.1 shenanigans that happened this week:
So... Show the roadmap at WWDC, ship a subset in September, then continue shipping features and APIs throughout the year. I think it'd be good for the platform, and it'd be good for developers as it would eventually reduce the need to rush through every summer implementing this year's new features while they are all in beta. It might mean that that WWDC week (after the keynotes) would need a shake up, but that wouldn't be the end of the world.
The most important part of this though that postponing features just a couple of weeks before developers were about to ship apps using them really isn't ideal. That's not news to anyone at Apple of course, and I know these decisions are not made lightly. But for the roadmap approach to actually work, we'd need to be told about the year's plan in advance.
I hope it's not too chaotic inside the spaceship right now, and I wish everyone working on the new releases good luck, no matter what makes it into the dot zero. 🤞Dave Verwer
