Hi, the 'Waiting to reconnect to [DEVICE NAME]' error is repeatedly occurring. Previous preparation error: Developer Mode disabled. To use[DEVICE NAME] for development, enable Developer Mode in Settings → Privacy & Security. Of course, the developer mode is already turned on and I've used the connection between my devices via XCode until yesterday. But it suddenly happened. I have several devices(iOS/iPadOS) so I've tried them all, but they are all having the same situations. What I've tried: Re-install XCode Rebooting mac and iPhone Safe boot my mac Disable and enable developer mode

Yesterday night, I opened the feedback app, but it kicked me out. When I reopened it, I had to sign back in, but it got stuck on a continuous loading screen. I tried swiping it from the background and reopening it multiple times, but it kept loading indefinitely. I waited for 1 minute, then 3 minutes, but it never stopped. This morning, I checked again to see if my reports had been opened, but the app was still loading.

Hi, here's an example: https://codepen.io/gyurmey2/pen/abgNQdE Is this even a known issue?

Hello all, With the release of iPadOS18, I face a strange behavior with the new UITabBar style. My custom navigation bar is completely broken. My back arrow is not showed anymore when a VC is pushed. It reappears when switching iPad on landscape mode. Some other people face similar behaviors ? Thank you in advance

I have a TabView with individual tabs containing NavigationSplitViews. On iPadOS 18, when moving the new UI into a sidebar, the title of the first column in the current split view randomly spins its way in and out of view. Is this just a beta bug, or am I doing something wrong? Hard to convey without a recording, but hopefully the screenshots will show what I mean. Thanks.

I'm pursuing a design that necessitates a dual app architecture — using a NavigationStack for compact-sized screens, and a NavigationSplitView for regular-sized screens. I've encountered what might be a bug in NavigationSplitView on iPadOS 17.x. Or perhaps it's a mistake in my code. When navigating into nested views (relying on NavigationPath), everything works fine... until I background the app on iPad. At this point, the navigation stack appears to collapse in the NavigationSplitView detail area — merging the parent and child views. Adding to the mystery... I can reproduce this bug on iPadOS 17.x. But the problem goes away when running on iPadOS 18.x beta. Key questions: Is there a problem in my code? Should I file a feedback with the Apple SwiftUI team? If iPadOS 18.x fixes this bug, can I expect a SwiftUI fix to be back-ported to 17.x or earlier? Steps to reproduce: Run my sample code on iPadOS simulator. Navigate to select a color, and then a shape. Put the app into the background (e.g., go to Home Screen). Return to app. What you can expect: When running on iPadOS 17.x, you'll see that the two most recent views in the stack have merged (meaning the title has changed, and the "back" button has disappeared). On iPadOS 18.x, you'll see that everything is working fine (title isn't changed, and back button remains available).

Hello, I’m currently working on Tiny ML or ML on Edge using the Google Colab platform. Due to the exhaust of my compute unit’s free usage, I’m being prompted to pay. I’ve been considering leveraging the GPU capabilities of my iPad M1 and Intel-based Mac. Both devices utilize Thunderbolt ports capable of sharing connections up to 30GB/s. Since I’m primarily using a classification model, extensive GPU usage isn’t necessary. I’m looking for assistance or guidance on utilizing the iPad’s processor as an eGPU on my Mac, possibly through an API or Apple technology. Any help would be greatly appreciated!

I have an extremely simple SwiftUI View with two buttons. One displays a sheet, the other one a popover. struct ContentView: View { @State private var showPopover = false @State private var showSheet = false var body: some View { VStack { Button("Popover") { showPopover = true } .popover(isPresented: $showPopover, content: { Text("Popover content") }) Spacer() Button("Sheet") { showSheet = true } } .padding() .sheet(isPresented: $showSheet) { Text("Lorem Ipsum") } } } On iPadOS, when the Popover is visible and the "Sheet" Button (that looks disabled but is not) is pressed, nothing happens and I get the following log: Attempt to present <TtGC7SwiftUI29PresentationHostingControllerVS_7AnyView: 0x14508c600> on <TtGC7SwiftUI19UIHostingControllerGVS_15ModifiedContentVS_7AnyViewVS_12RootModifier_: 0x14501fe00> (from <TtGC7SwiftUI19UIHostingControllerGVS_15ModifiedContentVS_7AnyViewVS_12RootModifier_: 0x14501fe00>) which is already presenting <TtGC7SwiftUI29PresentationHostingControllerVS_7AnyView: 0x140023e00>. What's even worse is, the "Sheet" Button is now in a broken state and no longer works at all. Is there a way to fix this or am I right in assuming this is a bug?

Hello, Has anyone encountered issues with CoreBluetooth advertising and scanning between iOS 18/iPadOS 18 Beta 3 ? I'm want to know this is a bug or an intended change in behavior. Issue Summary: Central device on iOS 18/iPadOS 18 Beta 3 (foreground) and Peripheral device on iOS 17.5.1 (background) fail to communicate via BLE advertising. The reverse setup or using non-iOS 18 devices works as expected. Detailed Description: I am developing an iOS/iPadOS application using CoreBluetooth for advertising and scanning. Here are the specifics of my setup: The application uses a fixed BLE service UUID, and scanning is performed with the specified service UUID. Background Modes Uses Bluetooth LE accessories and Acts as a Bluetooth LE accessory are enabled to allow advertising and scanning even when the app is in the background. When the Central device is running iOS 18/iPadOS 18 Beta 3 and the app is in the foreground scanning, and the Peripheral device is running iOS 17.5.1 with the app in the background advertising, the Central device cannot receive the advertisements from the Peripheral device. ( CBCentralManagerDelegate.centralManager(_:didDiscover:advertisementData:rssi:) don't work.) In the reverse scenario (Central on iOS 17.5.1 in the foreground scanning, and Peripheral on iOS 18/iPadOS 18 Beta 3 in the background advertising), the advertisements are received correctly. Additionally, advertisements are received correctly in cases where both devices are not on iOS 18/iPadOS 18. I am wondering if anyone else has encountered this issue or if there is any information available regarding whether this is a bug or an intended behavior change in iOS 18/iPadOS 18. Thank you.

The cursor is moved by the app in a Text area. iPadOS allows touch screen cursor movement to cut, copy, paste and insert text. When text is highlighted via handle controls, and cut requested, the app fails with cursor out of bounds. The app cursor was not moved in sync with IOS. It is obvious IOS does not sync with the app cursor position and the update of the endIndex.

Dear Apple Support Team, I am currently developing a control in my app that uses UIDatePicker for time input. To ensure that the time display format is consistently in 24-hour notation regardless of the region, I have set the locale of UIDatePicker to ‘systemLocale’. However, while this worked as expected up to iPadOS15, displaying the time in 24-hour format, it has switched to a 12-hour format from iPadOS16 onwards. I am wondering if there have been any changes in the behavior of UIDatePicker’s locale between the updates from iPadOS15 to iPadOS16? Additionally, I would like to know if there are any workarounds to this issue that do not involve modifying the program. In other words, is there a way to revert back to the 24-hour format without changing the code? Any information you could provide on this issue would be greatly appreciated. Thank you for your assistance.

Hello Apple, I am concerned about the new iOS Screen Mirroring that is available on iOS. I have an app that is only meant to be viewed on iPhones (not Macs or Computers, due to security reasons. I am assuming that Screen Mirroring is using AirPlay underneath, otherwise is there an API being planned or coming that can disable this functionality or is there a way for my app to opt out out of iOS Screen Mirroring? Thanks.

App is Xcode swiftUI on iPad using textview. The cursor is invisible yet it moves "underneath". How to make it visible. The app textview input is button characters and coexists with a Magic Keyboard where the cursor is visible.

I think iPad models with only WiFi need to have an sos or emergency calling feature Incase of any emergency.

I'd like to use the eye tracking feature in the latest iPadOS 18 update as more than an accessibility feature. i.e. another input modality that can be detected by event + enum checks similar to how we can detect and distinguish between touches and Apple pencil inputs. This might make it a lot easier to control and interact with iPad-based AR experiences that involve walking around, regardless of whether eye-tracking is enabled for accessibility. When walking, it's challenging to hold the device and interact with the screen with touch or pencil at all. Eye tracking + speech as input modalities could assist here. Also, this would help us create non-immersive AR experiences that parallel visionOS experiences that use eye tracking. I propose an API option for enabling eye-tracking (and an optional calibration dialogue within-app), as well as a specific UIControl class that simply detect when the eye looks at the control using the standard (begin/changed/end) events. My specific use case is that I'd like to treat eye-tracking-enabled UI elements or game objects differently depending on whether something is looked at with the eyes. For example, to select game objects while using speech recognition, suppose we have 4 buttons with the same name in 4 corners of the screen. Call them "corner" buttons. If I have my proposed invisible UI element for gaze detection, I can create 4 large rectangular regions on the screen. Then if the user says "select the corner" the system could parse this command and disambiguate between the 4 corners by checking which of the rectangular regions I'm currently looking at. (Note: the idea would be to make the gaze regions rather large to compensate for error.) The above is just a simple example, but the advantage over other methods like dwell is that it could be a lot faster. Another simple example: Using the same rectangular regions, instead of speech input, I could hold a button placed in just one spot on the screen, and look around the screen with my gaze to produce a laser beam for some kind of game, or draw curves (that I might smooth-out to reduce inaccuracy). OR maybe someone who does not have their hands available. This would require us to have the ability to get the coordinates of the eye gaze, but otherwise the other approach of just opting to trigger uicontrol elements might work for coarse selection. Would other developers find this useful as well? I'd like to propose this feature in feedback assistant, but I'm also opening-up a little discussion if by chance someone sees this. In short, I propose: a formal eye-tracking API for iPadOS 18+ that allows for turning on/off the tracking within the app, with the necessary user permissions the API should produce begin/changed/ended events similar to the existing events in UIKit, including screen coordinates. There should be a way to identify that an event came from eye-tracking. alternatively, we should have at minimum an invisible UIControl subclass that can detect when the eyes enter/leave the region.

IpadOS18.0 在主屏幕上有一个错误。请做好准备。只有一种方法可以解决它---重新启动系统。

I'd like to create meshes in RealityKit ( AR mode on iPad ) in screen-space, i.e. for UI. I noticed a lot of useful new functionality in RealityKit for the next OS versions, including the OrthographicCameraComponent here: https://developer.apple.com/documentation/realitykit/orthographiccameracomponent?changes=_3 I think this would help, but I need AR worldtracking as well as a regular perspective camera to work with the 3D elements. Firstly, can I have a camera attached selectively to a few entities, just for those entities? This could be the orthographic camera. Secondly, can I make it so those entities are always rendered in-front, in screenspace? (They'd need to follow the camera.) If I can't have multiple cameras, what can be done in that case? Is it actually better to use a completely different view / API for layering on-top of RealityKit? I would much rather keep everything in RealityKit, however, for simplicity.
