Using @Observable is great, but it has one small caveat. The initializer of the @Observable objects will be called multiple times, even with @State

@nilcoalescing.com's excellent article covers that topic in more detail.

Yesterday I joined a book club session with iOS developers at Expedia who have been reading SwiftUI Fundamentals (books.nilcoalescing.com/swiftui-fund...). We talked through less obvious parts of SwiftUI, and they shared very positive feedback about the book. Made writing it feel worthwhile 😊

Swift’s string interpolation system is more powerful than it first appears. Beyond simple value substitution, it can be extended to apply custom logic when values are interpolated. I’ve published a post showing how it can be done: nilcoalescing.com/blog/Definin...

Extend Swift’s string interpolation to define custom behavior, such as value formatting, directly inside string literals.

SwiftUI gives us a lot of control when styling SF Symbols, including custom foreground styles. One simple technique is to apply a foreground style with an inner shadow to make an icon look cut out from its background: nilcoalescing.com/blog/AddAnIn...
