iPadOS 18 TabView / NavigationSplitView title
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.

Emulated GCGameController not working with non fullscreen Designed for iPad apps on MacBook
Hello, I have an iPad app that users are running on their M1 / M2 MacBooks thanks to the "Designed for iPad" feature. Some of them reported to me that the pressed keyboard keys were not recognized. According to my source code, it seems that my custom views (that are set as firstResponder) do not get pressesBegan events. While I could not reproduce this specific problem on my M1 Macbook, I found a strange problem that may be related. My view also supports interaction with game controllers. I found that the emulated controller (which is using the keyboard, when the controller emulation feature of the Designed for iPad app is set to On) has some problems. The valueChangedHandler of the GCExtendedGamepad from the GCGameController is only fired if the app is compiled with the "Requires full screen" option set to On. If Requires full screen is unchecked in XCode, the Emulated Controller is still present in the list of game controllers, but no button callbacks are triggered. Note that a real game controller connected via USB will work correctly no matter how Requires full screen is set. Could there be a focus bug of the keyboard not sending events when the app is not a full screen app (resizable on mac, and multitask on iPad)? Or is there something I can change to avoid this problem? I'm lost.

Two audio streams from specific built-in microphones?
I have an iPad Pro 12.9". I am looking to make an app which can take a simultaneous audio recording from two different microphones at the same time. I want to be able to specify which of the 5 built-in microphones each audio stream should use - ideally one should be from the microphone on the left side of the iPad, and the other should be from one of the mics at the top of the iPad. Is this possible to achieve with the API? The end goal here is to be able to use the two audio streams and do some DSP on the recordings to determine the approximate direction a particular sound comes from.

Static lines when using Scribble
I just got the iPad air 5th gen and also the Apple Pencil 2nd Gen and right when I started using the scribble function, I would get random static lines along the lettering or random parts of the screen. it only appears when I'm waiting and doesn't affect the actual things I'm writing. The iPad also automatically updated to the beta version of ios 18 because my iPhone is also on the beta. Is anyone else having this issue?

Adalo App Submission Issue on IOS
Greetings to all! I recently developed an called DANZUB, the hub for dancers using the Adalo no-code tool. The App from adalo was directly imported into TestFlight on App Store Connect. When I released it for review, I got a rejection that app was not supported (display scale issue) on Ipad. I have primarily designed for IPhones and I do not know how I can adjust to IPads as well. I don't have this option on Adalo. Some said I could change the settings in XCode. But I don;t have the file, because the file was directly exported from Adalo to App Store Connect. I am unable to download the file. Please help, I am new to developing. So close yet so far. Thanks all!!

SwiftUI DropDelegate + Scrollview auto scroll while reshuffle the item outside of scrollview bounds
We have a feature requirement where we need to use LazyVGrid and DropDelegate. Our view hierarchy is as follows: Color.white.ignoresSafeArea() VStack(spacing: 0) { customNavigationView ScrollView(showsIndicators: true) { LazyVGrid(columns: columns, alignment: .center, spacing: 16) { ForEach(viewModel.selectedReferences, id: \.self) { item in ZStack { Rectangle() .fill(Color.yellow.opacity(0.5)) Text(item.title) } .frame (height: 120) .background(Color.white) .padding([.leading, .trailing], 4) .overlay((draggedItem?.uuid == item.uuid && changedView) ? Color.white.opacity(0.8) : Color.clear) .clipShape(RoundedRectangle(cornerRadius: 16, style: .continuous)) .onDrag { initialIndex = viewModel.selectedReferences.firstIndex { $0 == item } draggedItem = item changedView = false return NSItemProvider(object: String(item.uuid) as NSString) } .clipShape(RoundedRectangle(cornerRadius: 16, style: .continuous)) .onDrop(of: [UTType.text], delegate: DragRelocateDelegate(item: item, listData: $viewModel.selectedReferences, current: $draggedItem, changedView: $changedView) { endIndex in }) } } .animation(.default, value: viewModel.selectedReferences) } .frame(width:(UIScreen.main.bounds.width)) .onDrop(of: [UTType.text], delegate: DropOutsideDelegate(current: $draggedItem, changedView: $changedView)) bottomBarView } .frame(maxWidth: .infinity) } While performing a reshuffle, auto-scroll works within the bounds of the ScrollView content. However, according to the feature requirement, auto-scroll should also work when we place an uplifted view at the top or bottom of the view. STEPS TO REPRODUCE Launch the demo. Scroll to the bottom of the LazyVGrid. Pick any item using the DropDelegate. Try to place that uplifted view on the custom navigation view. Expected Result: The ScrollView should auto-scroll. Actual Result: Auto-scroll is not working.

Wake Up iPad from sleep into single app mode by BLE and Network
Hi, we actually have an application where we use iPad to run a WEB Application to display multiple Entertainment/Information content and control Infrastructure. The device is usually connected to a base station (own design) using BLE und USB only for power, is locked in single App Mode using MDM. As long as the App is open it is working fine. But now we like to go to the next step and like to have the device movable and use power save. How can we achieve the iPad wakes up immediately from sleep mode (directly to the app) if somebody is pressing a button on the base station (we support Comm Port, and HID Keyboard service, we can change code on base station if needed). And how can we achieve the same over Network (Wi-Fi or Ethernet with Adapter, Internet access is not always available). May set a state on the MQTT broker and tablet should wake up from sleep. Thanks for feedback Patrik

How to take back the control of our application ?
Good afternoon, I'm not used to the Apple tools and programms. We encountering the following issue : We have a zip file with an ipa file. According to our service provider, the Zip file contains the ios application which is presently already running on IOS (iphone, Ipad), only on the iphones and ipads of our team. The application is linked to the apple developer account of our service provider. Presently, this is the process we use to add the application on an IOS tools : We send the UDID of the tool to our service provider who generate an ipa file from the application. We put the ipa file in the following website : https://www.diawi.com/features-services The website give us an QRCode which we need to scan with the IOS tool, then, we have a pop-up on the tool for installing the application. It seems to be the process describing there : https://support.apple.com/fr-fr/guide/deployment/depce7cefc4d/web. As we won't work with our service provider anymore, we need to take back the control of the management of this application. We need to open the files in the .zip and we may have to modify them. I need some help to understand how to open them. I've tried on Xcode unsuccessfully. Could you please help to understand how to open and modify the application, linked it to our Apple developer account and distribute it to our employees or put it in the apple store ? Best regards.

SwiftUI Custom Card hoverEffect() Rounded Corners
Hi all, I am currently working on a user interfacing using SwiftUI where I have created custom button cards which have a mask modifier containing a RoundedRectangle with a corner radius of 15. The cards are displayed properly in the interface but when hovering over card with the iPad cursor using the hoverEffect() modifier or tapping and holding to show a context menu the corners aren't rounded and you can see a space where the rounded corners should be. Thanks! Here is the code for the custom card. var body: some View { Button(action: {}) { ZStack { Color("MainColor") VStack(spacing: 20) { Spacer() Text("Card content here") .font(.largeTitle) .bold() Spacer() } .padding() } } .contentShape(RoundedRectangle(cornerRadius: 15, style: .continuous)) .buttonStyle(.plain) .mask(RoundedRectangle(cornerRadius: 15)) .contextMenu { Button(action: {}) { Label("Edit", systemImage: "pencil") } Button(role: .destructive) { // Edit goes here } label: { Label("Delete", systemImage: "trash") } } .hoverEffect() }
