swiftui-observable

What problem does it solve?

Helps SwiftUI developers migrate from ObservableObject patterns and design class-based state models that provide fine-grained view updates, reducing unnecessary redraws and boilerplate.

Core Features & Use Cases

• Migration steps and practical patterns to replace ObservableObject, @Published, @StateObject, and @ObservedObject with @Observable and @State.
• Guidance for two-way bindings with @Bindable, excluding properties with @ObservationIgnored, injecting models via Environment, and using @MainActor for UI safety.
• Interoperability notes for SwiftData @Model, bridging legacy code, and advice for minimizing redraw scope in complex views.

Quick Start

Migrate your ObservableObject-based view model to @Observable, remove @Published annotations, replace @StateObject with @State, and update views to use @Bindable or plain properties for bindings.
