🍎hey everyone, I’ve been pretty quiet lately… today I’m diving back into #iOS development after a deep dive into cloud SaaS at scale. Exciting times ahead! #BackToRoots #iOSDev

And, ObservableObject is declared in Combine instead of SwiftUI... so we can get this for free outside SwiftUI if needed. – at Texas, USA

And just like that, BindableObject is now ObservableObject AND the publisher is auto synthesized! By just declaring conformance to ObservableObject, the publisher will automatically emit before any @ Published annotated properties change. YES! #swiftui – at Texas, USA

#swiftui beta change heads up, BindableObject’s publisher now needs to emit BEFORE changing the bindable object’s state. Publisher now named willChange. This means using willSet instead of didSet or calling .send() in a method right before changing a property’s value. #iosdev – at Texas, USA

Handy #swiftui tip, if you’re hesitant to use .onAppear, don’t worry. SwiftUI won’t call onAppear every time your view struct is re-created on state change. onAppear is a great place to start side effect loading I/O. SwiftUI must be correlating old-new views. #iosdev – at Texas, USA

So far, SwiftUI + tooling is everything I’ve ever wanted out of a UI framework. Can’t wait to dig in. – at Texas, USA

Hi everyone, great news! The first edition of Advanced iOS App Architecture was released today! If you want to learn more about dependency injection, unidirectional architecture and what to look for in a great architecture, this book is for you. store.raywenderlich.com/prod… – at Austin, TX
