Apple Pencil unlocks a different way to interact with iPad, which can be both efficient and comfortable. I’ve implemented enhanced support for Apple Pencil in our product and would like to share what I learned.
This would be most beneficial to anyone making an iPad app that supports drawing. However I think Apple Pencil could enhance other kinds of apps too, and the topic is generally interesting.
The talk would cover both design and implementation:
- I would discuss the benefits of Apple Pencil for users and what features it works well for.
- The next part is implementation: firstly detecting the Pencil and distinguishing it from finger touches.
- I would go through how we can increase realism and responsiveness using coalesced and predicted touches.
- Finally we would look at performance. While this is highly dependent on your codebase, I can share some general tips for using Instruments to identify bottlenecks and some possible ways to make your code faster.
