apple pencil charging

Hello, The Apple Pencil Pro brought with it the UICanvasFeedbackGenerator API, which lets us trigger haptic feedback on discrete events initiated by the pencil. That works fine. My question then: is it possible / are we allowed to trigger haptic feedback on events that weren't initiated by the pencil? For example, say the user is using a left hand finger to drag a slider, while holding the pencil in their right hand-- would it be possible to make the pencil vibrate to indicate the dragged slider knob reached a certain point? Or is the rule that vibration is only possible/allowed when the pencil itself generated a touch? Thanks!

Why is there no Apple Pencil Support on the iPhone?

Your app playground must be built with and run on Swift Playgrounds 4.4 or later (requires iPadOS 16 or macOS 13.5, or later) or Xcode 15 on macOS 13.5, or later. You may incorporate the use of Apple Pencil. If I want to develop a playground for the iPad and Apple Pencil, am I limited to using Playgrounds on iPadOS to make it? Or could I also use Playgrounds on macOS and Xcode? If I use Xcode to make my iPad playground, should I select Xcode for Which software should we use to run your app playground? I assume so, as I used Xcode to make my app — but then it will be run in a simulator by the judges, which means they cannot use the Apple Pencil. I'm a little lost here. Any guidance is appreciated.

Someone help! I lost my Apple Pencil 2 days ago and when I went to troubleshoot to find it, the Apple Pencil disappeared from my Bluetooth pairing list?? I don’t know what happened, if someone could help, I would appreciate it a lot!

Dear Apple developers. I found a crash problem，Apple Pencil crashes when written in a textField. See attachment for details.I hope you will reply after reading this and give a solution.

I used Apple Pencil to input text on UITextView, but the program crashed when I long pressed and tried to use the insert function. warning: Module /Users/baochengzhu/Library/Developer/Xcode/iOS DeviceSupport/iPad14,1 17.0.3 (21A360)/Symbols/usr/lib/libobjc.A.dylib uses triple arm64e-apple-ios17.0.0, which is not compatible with the target triple arm64-apple-ios11.0.0. Enabling per-module Swift scratch context who can help me ?

Apple pencil connected but it doesn't work. It was working on the non beta version of IOS.

Dear All,Will iOS SDK provide APIs for Stylus/Pen Application Programming while the Apple Pencil has been public launched? That means, how an Application Programmer can let the Application via official iOS SDK APIs use/access the information related to the location and applied force of the pen tip of the Apple Pencil during writing/drawing? Please advise your valuable comments. Thanks.Curtis

Good day. I'm inquiring if there is a way to test functionality between Apple Pencil Pro and Apple Vision Pro? I'm trying to work on an idea that would require a tool like the Pencil as an input device. Will there be an SDK for this kind of connectivity?

I am able to connect the Apple Pencil, but I am unable to use it to write in Notes (Bluetooth is fine, have 'forgotten device and reconnected). It will select apps and other items, but can't be used to write notes.Ideas?

I have a drawing app that I created and have sold on the App Store since 2018. It requires an Apple Pencil. My app uses the azimuth feature to orient the brush pattern that is drawn on the screen. A user just contacted me and said his azimuth feature is not working. Now it works fine for me, and I have not heard complaints from other users, so this leads me to believe it could be a problem with his Pencil. I wanted to show my code just to rule out that the problem is on my end and also get suggestions on what I should tell this user to do. Should he just contact Apple about it? // calculate the pencil direction let vector1 = touch.azimuthUnitVector(in: selectedCanvas) let angle = atan2(vector1.dy, vector1.dx) let azimu = angle - CGFloat(Double.pi) / 2.0 // adjust for wonky azimuth rotation translation if azimu >= -4.5 && azimu <= 0 { rot = abs(azimu) } else { rot = 6.2 - azimu } The azimu is then used as a point rotation in a basic Bézier curve and dr
