Apple tweaks guidelines for children’s apps and sign-in services
It's good to see Apple being reasonable and rolling back slightly on some of these guidelines. The one you're most likely to be affected by here is the amendments to "Sign in with Apple". Nothing huge is changing, you still have to implement it if you are using other "Sign in with ..." buttons, but some edge cases are now being coped with.
Yes, this information is available in the documentation, but there's absolutely no substitute for seeing how size classes, layout margins, safe areas, context menus, navigation/split views and so many more things work on real devices. Geoff Hackworth has updated his Adaptivity app for iOS 13 and it's just as good as ever.
Tweak a parameter, build and run, tweak a parameter, build and run, tweak, run, tweak, run... If you've ever used anything more than a very basic particle emitter in your project then that cycle is going to sound very familiar. Luckily Besher Al Maleh has put together this extremely comprehensive settings explorer for
CAEmitterLayer and friends. There's also more information in this blog post if you'd like a bit of background.
Scroll View Layouts With Interface Builder
I had missed that Xcode 11 had added support for iOS 11's layout guides, but then I read this post from Keith Harrison and he put me straight! 👍 You should read it too.
Apple Push Notification Device Tokens
Don't get too distracted by the slightly obtuse opening paragraphs in Mattt's latest NSHipster article, there's some very important information here. Also, be aware that you'll only see this behaviour when you build with Xcode 11. If you use push notifications, you want to read this.
SwiftUI by Example
I linked to this before, but since Paul Hudson has been through it and updated every bit of it for the Xcode 11 GM seed, and also recorded a whole new set of 14 videos to go alongside it, it's worth another look. There's so much broken SwiftUI content out there due to the constant changes this summer, it's nice to know that everything here is going to work with the released version of Xcode.
Supporting the iOS Billing Grace Period
I linked to the news about the subscription grace period last week, but didn't offer any advice on how to deal with it. Here's Jacob Eiting with exactly what you need to do.
The Simple Life(cycle) of a SwiftUI View
Great article from Danny Bolella on the much simplified view lifecycle in SwiftUI. He argues (and I agree) that Apple don't want you to think about the lifecycle much because it's much less important now that data is bound automatically to views. 👍
iOS 13 UISegmentedControl: 3 important changes
It may seem like the new design for UISegmentedControl is just a straight drop in replacement for the old class, and if you're not customising anything then you're right! However, Rostyslav Dovhaliuk is here with a great little article on some of the edge cases you might want to keep in mind if you're using this class.
There's conference talks, meetup talks, and presentations of all kinds covering iOS development here. List talks by year, by conference or just search for something specific.
This site, put together by Khoa Pham isn't new, but it's a complete re-design and it's much faster and nicer to use than the old version. 👍

Disable Autocorrection in SwiftUI
This may have been inspired by what the Xcode team were saying when they realised they needed a second GM seed of Xcode 11! 😂
We've got new phones in our hands, watches on our wrists, and a second release of the Xcode 11 GM seed on our hard drives that fixes the asset catalog bug. Does September get any better than this?
Actually, it probably does as it's only 4 days until 13.1 arrives! 👍Dave Verwer
