Taptic Engine Playground

This example was used to discover the Apple's usage of Taptic Engine functions. It's actuation methods are hidden in UIDevice and _UITapticEngine classes and are called by UIPreviewInteractionController when appropriate.

This original sample displays a UITableViewController that triggers view controller previews, using preferredContentSize to show previews of different sizes. The sample also includes single-item and grouped action items.

Research

The methods and classes for Taptic Engine can be found using Runtime Headers, look for UIDevice and _UITapticEngine classes.

The values for peek and pop were discovered using Aspects and this is an example output:
