“Trait-ifying” our libraries to reduce transitive dependencies

Point-Free is adopting SwiftPM traits across their Swift libraries to let users opt out of transitive dependencies they don't need. Using SwiftNavigation as a test bed, developers can now specify traits like CasePaths and Perception in Package.swift to avoid pulling in libraries like CustomDump, IssueReporting, and Sharing. The Dependencies library also supports traits to omit clock/Combine scheduler registrations and even Foundation/FoundationNetworking for Wasm and Android targets. Xcode provides a new UI for managing these traits. More libraries, including ComposableArchitecture 2.0, are getting the same treatment.

New macros for SwiftNavigation

SwiftNavigation 2.9.0 introduces two new Swift macros. The first, @CaseBindable, lets you derive bindings to individual enum-case payloads, enabling exhaustive switch statements over SwiftUI Binding<Enum> values to extract typed bindings for each case. The second, @UITransactionEntry, reduces boilerplate when defining custom UITransaction keys — mirroring SwiftUI's @Entry macro but for the library's platform-independent UITransaction type. Both macros are back-deployed to iOS 13.
