Reply to Is there a scribble gesture for new line/return?
I am also requesting a manual scribble new line request. It would be helpful to have a manual new line function to the apple pencil rather than some time automated feature. I would suggest scribble create a new line when the pencil is in eraser mode and the user makes a down and left arrow gesture (the symbol on a lot of keyboards for return) while not erasing anything.

Reply to Apple Pencil support in Safari
Ok. Thanks for your reply. No 3D touch is actually fine. I just need to get regular touch (without pressure sensitivity) to work.Right now, when regular touch is used, nothing happens, as force is 0 (default) and hence detected as no pressure.Note that when using the Apple Pencil it can also return a force of 0. So I suspect this is valid.So either I have to 1) disable Pencil pressure sensitivity, or 2) Ignore regular touch.However, none of those options sound very appealing.So to rephrase: Is there any way to detect if a touch event is coming from regular touch or from the Apple Pencil, or better yet, if force is updated and accurate?Thanks a bunch.Best,-karma

I wouldn't over think it too much, Sidecar runs like a champ in my experience and the iPad Pro runs great with or without a cable hooked up. Apple did their homework very well building Sidecar. I can open Affinity Photo using Sidecar and use the Apple Pencil to edit photos like the application was built for pencil. I'd say even for a beta, its a pretty solid feature.

Payment charged but Apple Developer Program not activated (no confirmation email)
Hi everyone, I enrolled in the Apple Developer Program and paid for the membership through the Apple Developer app on my iPhone on January 20, 2025. The membership fee was successfully charged to my debit card. However, I never received any confirmation email, invoice, or receipt for the payment, and the subscription does NOT appear under my Apple ID subscriptions. As of today, my developer account is still not active, and I’m seeing inconsistent information across platforms: In the Apple Developer app, I now see a message saying that I can’t enroll with this account, even though the payment was charged. On the developer.apple.com website, it says that I still need to purchase the membership. I’ve already contacted Apple Developer Support via email, but I haven’t received any response yet. Has anyone experienced a similar issue where: The membership fee was charged, No confirmation or receipt email was received, The subscription does not

Does the Apple Pencil report correct pressure at the start of each stroke?
I'm seeing some odd behaviour when using coalescedTouches and the Apple Pencil to retreive force data. IT seems that no matter what force is applied, the first few points that are captured have a force that is always 0.33333333 no matter the force or device used. Once the stroke continues this value seems to settle down into expected values. Has anyone else seen this behaviour? Here is a CSV dump of a test run where you can see the force value (under 'P') starting at 0.333333 for each stroke:Stroke Index,Point Index In Stroke, X, Y, P, T, Altitude, Azimuth 0, 0, 241.0, 524.5, 0.333333333333333, 880868.541, 1.13556988636521, 0.213184996447291 0, 1, 240.0, 524.0, 0.333333333333333, 880868.546, 1.13556988636521, 0.213184996447291 0, 2, 238.5, 523.5, 0.333333333333333, 880868.55, 1.13556988636521, 0.213184996447291 0, 3, 237.5, 523.5, 0.333333333333333, 880868.554, 1.13556988636521, 0.213184996447291 0, 4, 237.5, 523.0, 0.333333333333333, 880868.558, 1.13556988636521, 0.213184996447291 0, 5, 237

SSC Distinguished Winner here😃! I created the1st game 100 % using Apple Pencil to interact. Interested in joining our DC?
Hey everyone, I'm beyond excited to share that I've been selected as a Distinguished Winner in this year's Swift Student Challenge! 🎉 It all started last summer, in the middle of a Western Culture class. I was zoning out , and my attention drifted to the Apple Pencil in my hand. And then ,it hit me — this thing is literally a next-level game controller. Think about it: pixel-perfect precision, haptic feedback, multiple built-in sensors... Why aren't we using this for gaming? And that got me thinking — why have we spent the last 500 years treating the pencil as just a tool for creation, and not for play? Since graphite pencils were invented in 1564, we've had this incredibly natural way to interact with 2D and 3D space... and nobody's fully tapped into it for games. So, I did something about it. I built a game that's 100% controlled by the Apple Pencil yep, just the Pencil. I know what you're thinking: How does that even work?? And honestly, I'd l

Loss of information with Wacom pen in 10.10.4
(writing this post again, since it seems to have disappeared. If this is not the right place to post that, please let me know)I am writing this to report a bug that we discovered with the latest update of MacOSX Yosemite, 10.10.4. I am not sure if this is a bug on Apple’s side or on Wacom’s (I have notified Wacom of this bug).After updating to 10.10.4, there is a loss of information when drawing with the stylus, whether on an Intros or a Cintiq (our Wacom drivers are up-to-date)The issue disappear if we go in Fullscreen mode, however. Here’s a screenshot, which will probably be more explicit.This bug also appears in Gimp, Krita (it’s even worse in Krita) and a little bit with Artrage. I haven’t been able to reproduce it on Photoshop however.So, my questions is, did something change in Cocoa's recognition of external peripherals (like Wacom tablets and styluses) in 10.10.4 ?This is not the first time that this appears (we actually fixed it at least half a dozen times since Mountain Lion...) a

Reply to Announcing the Swift Student Challenge 2026
Framework compatibility: My app uses Foundation Models and Apple Pencil. The app runs great through Xcode; however, due to Apple Pencil support, it has to be run on a physical device. However, Swift Playgrounds on iPad doesn't support iOS 26. I was just wondering if this is something that can be mentioned in submission notes. eg. The app needs to be compiled in Xcode but run on a physical device.” Or should we expect iPadOS 26 support for Swift Playgrounds by the time of submission? Thank you!

pencil kit issue--drawing can't stay on canvas
I want to use pencil kit in my swiftui app. I encapsulate PKCanvasView in UIViewRepresentable. I can draw on canvas with only one stroke. However, the image will disappear immediately when I release the finger. Am I missing anything? import SwiftUI import PencilKit struct ContentView: View { var body: some View { CanvasView() } } struct CanvasView: UIViewRepresentable { func makeUIView(context: Context) -> PKCanvasView { let canvas = PKCanvasView() canvas.tool = PKInkingTool(.pen, color: .green, width: 10) canvas.drawingPolicy = .anyInput return canvas } func updateUIView(_ uiView: PKCanvasView, context: Context) { } }

Reply to How to increase the width of PencilKit .pen stroke?
Investigating this I've come across a computed variable in the default PKInk named validWidthRange it has these ranges: for .pen: 0.8781664588318914...25.659259612471967 for .pencil: 2.4000000953674316...16.0 Is there any way I can increase these ranges? Or crate a copy of .pen PKInk with my own validWidthRange?

Apple tries to double charge me for enrollment
I enrolled to the program via the Developer app and paid for the subscription, got my receipt. The app now says the enrollment is not available. Xcode says I have no developer account. The Appstore mac app says the subscription is active. The developer website says I need to pay. Again. Is this some kind of scam or what?
