For games that share a common codebase with multiple targets, what would be the recommended way to handle accessibility? For example an iOS game with a WatchOS companion that can played standalone. Any word how Voice Control will affect this combination? For iOS 26, I've had to handle some aspects of accessibility separately and needed to separate out some of shared codebase into each target.

What's the recommended pattern for sharing a complex SpriteKit game scene (and basic game code) between iOS and watchOS targets without code duplication, given the platform differences in input and rendering?
