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

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

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

iOS 18- charging
Since updating my iphone 12 to iOS 18, my phone either doesn’t charge unless the wire is in a certain position or if it is charging it’s very slow. I’ve tried multiple wires with multiple plugs and it’s all the same. I had no issues before updating and now wish I hadn’t updated because I can’t afford to go and buy a new phone.

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) { } }

Wireless Charging issues
I had wireless charging issues after downloading iOS 14 with my iPhone X and now having the same problems with the new iPhone 12 pro. It must be an issues with the operating system. Does anyone have an idea when Apple might try to solve this issue? It charges and then stops and starts multiple times. I've tried everything I've seen and read about but still continue to have the problem. Come on Apple ... after spending a grand for your new phone at least you can fix this problem.

Reply to Stabilize Curve with CGPath
Yes I mean Bezier path. Basically when the user drags across the screen (with the apple pencil or other stylus for example) their hand will naturally shake a little bit, so the points being added to the curve are not perfectly straight. I was hoping for a way to move the points closer together regardless of their natural hand jitter. Other drawing apps typically call this a brush stabilizer.
