Haptics

The workflow is straightforward: pick your complexity level, prepare generators before triggering to reduce latency, and follow the Causality, Harmony, Utility framework to avoid annoying users. The common mistakes section is worth reading. Overusing haptics drains battery and irritates people, and the reminder to always pair haptics with visual or audio feedback for accessibility is easy to forget. Requires iOS 10+ for basic feedback, iOS 13+ for custom patterns, and you need a physical device since the Simulator won't help you here.
