Migrating ObservableObject to the @Observable macro involves scanning Swift files to update class definitions and replacing legacy view property wrappers like @StateObject and @ObservedObject with modern alternatives like @State and @Bindable to improve view update performance.
The best way to modernize legacy iOS codebases is to generate a migration report that identifies deprecated SwiftUI modifiers and suggests updating to modern declarative patterns, replacing completion handlers with async/await syntax.
Replacing @EnvironmentObject with @Environment requires updating view property wrappers to iOS 17+ standards, reducing boilerplate by shifting to the @Observable macro for model management rather than relying on older ObservableObject protocols.
You can automatically convert completion handlers to async/await by scanning target Swift files within a repository to detect deprecated patterns and provide modern async/await paths for improved code readability and adherence to Apple best practices.
Modernizing SwiftUI property wrappers to use @Observable, @State, and @Bindable requires targeting iOS 17 or iOS 18 deployment environments, as these specific macros and property wrapper standards are unavailable in earlier legacy operating system versions.
Migrated @Observable models may trigger view update issues if legacy property wrappers like @StateObject are not fully cleaned up, requiring a thorough replacement of deprecated modifiers to achieve improved view update performance.
