Designing a modern Feature Flags Controller
summary
A Swift library that implements a Feature Flags Controller using Combine publishers and an ObservableObject view factory to register and update views, with a dictionary-backed storage of publishers and generic flag types. It composes local and remote flag sources, maps notification center updates into publisher values, exposes a lightweight protocol for view access, is open sourced on GitHub, runs in production apps, and claims to avoid long-term flag debt while enabling hot toggles and view-level flag composition.
