Retrieve Apple Pencil Pro Orientation, Roll outside of HoverPose?
I'm attempting to retrieve the values of the Pencil Pro using the new PencilHoverPose, however according to the documentation it appears these can only be accessed while in a hover state (0 to ~0.5 from the screen). Is there a way to get the orientation or roll values of the Apple Pencil Pro outside of a hover? I'm attempting to use the pencil as an input device, necessitating it be farther from the screen than 0.5 Below is a simple view I'm using to display the available values: import SwiftUI import UIKit struct PencilSqueezeView: View { @State private var squeezeText: String = Squeeze the Apple Pencil Pro @State private var hoverDistance: CGFloat = 0.0 @State private var anchor: UnitPoint = .center @State private var location: CGPoint = .zero @State private var altitude: Angle = .degrees(0) @State private var azimuth: Angle = .degrees(0) @State private var roll: Angle = .degrees(0) var body: some View { VStack { Text(squeezeText) .font(.largeTitle) .pad

Reply to After Installing MacOS Big Sur latest beta update, My mac is showing battery service required warning in battery Icon.
I had the same issue, I updated my Macbook Pro from Catalina to Big Sur, and the battery life was terrible and my computer would get boiling hot. I got a message saying that battery capacity is significantly reduced and I powered off my computer and start it up while holding Command + Option + P + R, which reset the PRAM and solve the message but my battery life was still trash, I then check my CPU usage and there was an app called Google Chrom Helper which took up 95% of my CPU usage. I force quit it then immediately notice a cooler Mac and faster response times. I would try looking at CPU usage first.

Same iphone 6s ios 14.1. After install ios 14 battery life it's go to be terrible. 14.1 is the same with little improvements. Steve Jobs was a great man, and now his absence in Apple is most felt.

Reply to Battery Life horrible on watchOS 2 beta 5
I had the same problem here, battery died within four hours. Most of the third party apps didn't work but after having unpaired and re-paired the watch the problem seemed to have disappeared. All Apps running as thye are suposed to. The battery life is now signifiacntly longer. However when running the workout app ( displaying HR) the battery is draining really fast and after half an hour of running the battery goes from a 100% down to 40%.

UIViewController not handling Apple Pencil Double Tap events
I am unable to get a UIViewController to receive the UIPencilInteractionDelegate “pencilInteractionDidTap” method in response to double taps from an Apple Pencil. I am testing on iPad Pro 11 and 12.9 models, both running iOS 13.3.1I have implemented the following:extension UIViewController: UIPencilInteractionDelegate { public func pencilInteractionDidTap(_ interaction: UIPencilInteraction) { print(Handle pencil double-tap) }}In my UIViewController:override func viewDidAppear(_ animated: Bool) { super.viewDidAppear(animated) let pencilInteraction = UIPencilInteraction() pencilInteraction.delegate = self view.addInteraction(pencilInteraction)}Note: If I create a new Single View iOS app and add this code, everything works as expected.However the above code does not work with the custom UIViewController in my app. My UIViewController’s view hosts a UIScrollView as well as overlaying Container Views and handles touch events in both the View Controller and ScrollView classes.I have also

Adjusting Pen thickness in Markup and Notes
I seem to be getting varying thickness in both Markup and Notes when using the Apple Pencil in pen mode and I have no idea how I’m changing it. Sometimes it’s quite thick almost like a sharpie and other times it’s quite fine like a .5 pen. It’s nothing to do with how hard I’m pushing on the screen, it’s literally like 2 different pens/thicknesses and I’v no idea how I’m doing it. Been trying all sorts of things on the screen and can’t seem to change them over. Any ideas as it’s doing my head in!!Thanks in advance.

Reply to After Installing MacOS Big Sur latest beta update, My mac is showing battery service required warning in battery Icon.
Same issue with the non-beta 11.1. 13 2018 Touchbar MacBook Pro. The day after I updated the battery failed (the last time I checked the battery life a few months ago I was at 98%). Couldn't start the computer for 2 days—just got the red dead battery icon on a black screen when trying to restart. Resetting SMC and PRAM did not help. Apple support sent me to a local certified reseller/service and they said top case/battery replacement was needed at ~$700 (I am out of Apple Care coverage I also discovered...). Not happy about it! I ran out and picked up a little MacMini so I can keep working while this gets sorted. It seems this may be a firmware issue in the SMC or Battery? Hope this gets acknowledged/resolved before* I need to replace the battery/top case. I also posted about this in the Macrumors forum (referencing this thread) to see how many people are experiencing this.

Reply to Beta 5 battery life?
Update on battery life. I second that ensuring that the phone and watch are on the same beta is vital. It also took a full unpair/repair of the watch. As an added bonus I set reduce motion in the watch settings to on. I've had the watch on for two hours today, with little to no interactive use, and it still reports 100%. Previously animating my constant time checks alone sapped the battery. Yesterday, with all of the above done and regular interactive use, I had 50% battery after 16 hours. Well done Apple. Let's not lose the progress! :)

Glad to hear it. Every bit of CPU and battery life you can save makes for a better user experience. Good luck with your game, by the way! 🙂

Reply to Caution: watchOS 26 Beta 2 (may) brick Hermes variants
I’d like to add my voice to this also. Hermes S7… same exact results. I even tried allowing battery to die down for 24 hours. put it on the charger and got 16 % battery before it turned and drained down to the loop of 2% battery life. Dies. Charges to 2% repeat cycle. Yes the Watch app also doesn’t open.
