USB Accessory Device Charging Behavior Changed with iOS18
Hello, We are experiencing some issues with our USB accessory unexpectedly charging the iOS device it is connected with only when the iOS device supports USB-C and is on iOS 18+ The following is a description of the discrepancy we note between iOS versions: After performing a USB Role switch, our Accessory becomes a typical USB Device and the Apple device becomes the USB host. with iOS 17: 
 The Accessory then sends a PowerSourceUpdate message to the iOS 17 device via iAP2 protocol. Apple device has a USB Type C Connector. * We are specifying: AvailableCurrentForDevice = 0 mA DeviceBatteryShouldChargeIfPowerIsPresent = 1. Three observations: iPad Battery Settings page - we observe 'Last charged to…' (indicating no charging) On the Lumify App running (iOS 17), we observe that UIKit.current.batteryState indicated 'Not charging' Battery icon on top right of the screen indicates 'No Charging' with iOS 18: The same Accessory sends the same PowerSourceU

Can we charge customers this way and get approved?
Hey everyone! I have a question on how we would generate revenue in the app I'm building. In short we're creating a platform that allows influencers to host exclusive lives to 1000 of their core fans. We want to make where when a fan joins a Live they're charge per minute. There are two options we can go with according to Apple. Option 1 Users can load money onto their account ($1, $5, $10, etc) from Apple Pay or with their debit card. When they upload money onto their account they can join a Live. When they join we will charge this user $0.08 cents for every minute their inside a Live. If they run out of funds on their account their kicked out of the Live if it's going, otherwise if they have the funds in their account they can continue to stay in the Live until it ends. You can view apps like Starbucks when you have to reload your rewards card balance. You also have Spin Scooter where you have to upload at least $10 to unlock a scooter. When you use a scooter Spin takes t

Apple Watch Ultra exercise app and activity rings won’t connect after charging
Since upgrading to iOS 26 beta on my Apple Watch Ultra and iPhone 16 Pro Max, my exercise app and activity rings have sporadically not connected after charging. Several recent mornings, when I’ve put my watch on, the activity rings are grayed out and when I click on them, they will show no activity, even though I have been active. Similarly, when I attempt to select the activity app, it will open, but when I select an activity, it will not start the workout. I’ve tried starting and restarting the watch and phone. I’ve checked permissions, and both the watch and phone are running the latest iOS. The only fix seems to be unpairing and repairing the watch and phone which is an absolute pain. Any assistance on how to permanently fix this would be greatly appreciated.

Reply to How to use PDFPageOverlayViewProvider?
With omar_a's suggestion, I succeed in presenting overlay views for a PDF file. But the issue is I can not draw anything on canvas as WWDC's demo video. In the video, the presenter overlaid a canvas view and draw with his pencil. But I can't make the same. Should I make some custom gesture handlers PDF view to activate pencil input?

Reply to Wireless charging broken in iOS 13 Beta 3
I noticed a problem as well using a charging stand I got from Amazon. It is supposedly a Fast Charger so I've had it connected it to an iPad A/C adapter.Up until installing beta 3, it was charging fine but now it isn't. The phone will beep and the charging icon will show up but the phone won't charge. I have another charging disk that I found will charge the phone with beta 3 but it's not a fast charger. I tested the other one but changed the A/C adapter to a standard iPhone brick and found that the phone will charge now. I think it may have something to do with the higher output of the iPad adapter. It's not the charger either because I have an iPhone 8 running iOS 12.3 and it charges fine with either A/C adapter.I've reported the issue to Apple.

iPhone XS Max not charging
Hello,I installed iOS 13 beta on my iPhone XS Max successfully. Sometime and after hard usage I got a message to charge my phone.I connected to its charger but unfortunately the phone was not charging.I decided to reinstall the beta but this time to make it as a new phone. Unfortunatelly I had the same results.Since the battery percentage was at 7% I decided to go back to 12.4 beta 3 successfully where my iPhone was charging properly and without any problems. It seems that there is a huge issue on the software. I reported as well as a bug.Does anybody else faced the same issue?Thanks

Reply to Lasso no longer works with iOS17
Sorry, this one is even simpler. import SwiftUI import PencilKit struct ContentView: View { @State var canvas = CanvasTest() var body: some View { VStack { canvas Text(Pen) .onTapGesture { canvas.canvasView.tool = PKInkingTool(ink: PKInk(.pen), width: 4) } Text(Lasso) .onTapGesture { canvas.canvasView.tool = PKLassoTool() } } .padding() } } struct CanvasTest: UIViewRepresentable { let canvasView = PKCanvasView() func makeUIView(context: Context) -> some PKCanvasView { canvasView.drawingPolicy = .anyInput canvasView.tool = PKInkingTool(ink: PKInk(.pen), width: 20) return canvasView } func updateUIView(_ uiView: UIViewType, context: Context) { } }
