January 2025 — Square/workflow-swift focused on reliability and maintainability of SwiftUI environment handling. Implemented a targeted correctness improvement by enforcing sub-properties for environment references to ensure correct view invalidation, reducing subtle UI bugs during state changes. Introduced a deprecation warning and a fatal error for top-level @Environment(.viewEnvironment) usage to steer developers toward safe patterns, enabling earlier detection of incorrect usage in both development and CI. Updated the test suite to reflect the new behavior by referencing specific environment keys to prevent incorrect invalidation, improving regression coverage. The change aligns with issue #319 and is captured in commit 0811a5d3a5608185ddc4984aaf2fb5d876e84cc8. Overall impact: more predictable UI invalidation, safer refactors, and clearer developer guidance that translates to reduced debugging time and higher code quality.
