apple pencil battery life

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

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 ?

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?

Batteries widget shows that the Apple Pencil is charging but the percentage isn increasing. Charging is still possible through the wall adapter for Apple Penci.

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?

after download iOS 10.2 beta 3, my iphone's turning off when it's with 12-10% of battery.Someone else? If positive, please say how did you fixed it.PS: i'm getting worried about it.

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
