Starting with iPadOS 18, which will be widely released later this year, iPad apps can offer custom drawing tools for the Apple Pencil.

For example, in a WWDC 2024 coding video last week, Apple demonstrated how an app could implement a tool that allows for cat paw prints and other animal-related symbols to be added to a drawing. The custom tools support features on the new Apple Pencil Pro, including the squeeze gesture and barrel roll action.

iOS 18 and visionOS 2 also support custom drawing tools in apps, but the iPhone and Vision Pro do not support the Apple Pencil. As always, any drawing tool can also be controlled with your finger and other input methods.

In addition to custom tools, apps across iPadOS 18, iOS 18, and visionOS 2 are able to change the selection of default drawing tools that appear in the system tool picker. Apple said apps are even able to offer multiple tools of the same type for added convenience, such as two colors of pens or two colors of markers.

iPadOS 18, iOS 18, and visionOS 2 are currently in beta.

They say this but the support for custom tools is very bare bones. The custom tools get a very generic look in the tool picker with only a basic icon to differentiate them from built-in tools (see the paw print icon on the custom tool in the screen grabs). The custom tool content also has to be rendered in a separate view from the rest of the drawing, so developers do not benefit from Apple's gesture handling or low latency rendering. For this reason developers cannot intermix their custom tool drawing content with the built-in tool drawing content. If you run the sample code the paw prints are always on top of the built-in tool content, even if you go in and try to draw on top of them, which is pretty unacceptable.

I hear a lot of people suggesting that developers "just use pencil kit". But for many applications it's just not flexible enough and continues to not be flexible enough.

It would be nice if Apple spent some effort including more AI tools into the drawings. Like, if it knows what you are drawing and the style you are using, it could suggest colors or textures for that. It could also straighten out your lines as well. All optional stuff but for certain drawings it would help a lot. Like technical drawings, it would straighten the lines up more as you draw them. Having the ability to edit the shape of the last shape you draw would be nice too. Frankly the company is big enough to have dedicated teams for all their apps, they can enhance things quite a bit in one year. Would make blips like the be more newsworthy.

Isn't it a violation of human rights or something that the iPencil doesn't work on other tablets, and that other tablets can't use the iPencil? Where's the EU when you need them?

If there’s a violation, it’s you calling the Pencil “iPencil”.

Also, the way Pencil is made, it’s technically impossible. Just like Wacom Pro Pen doesn’t work with non-Wacom devices even if their EMR pens work on lots of devices.

Very nice. Will be interesting to see the various options the different apps will have.

They’ll be there when a company based out of the EU makes a digitizer that Apple won’t allow to work on the iPad.
