RelevanceKit

Use RelevanceKit to tell the Apple Watch Smart Stack when a widget matters by time, location, fitness state, sleep schedule, or connected hardware. Targets Swift 6.3 and watchOS 26+ relevant-widget workflows.

Beta-sensitive. Re-check current Apple documentation before changing availability, signatures, or Smart Stack behavior.
