If two iOS/iPadOS devices have your app opened, is it possible to have the apps send data to each other over a wired connection? E.g. If two iPhone 15s are connected by USB-C, can I get my app in iPhone A to send data to iPhone B and vice-versa? I've been looking around for quite a while now and at this point I just want to know if it's technically feasible.

I figured out how to use a Mapkit offline in swift and make the map usable offline . Would a project with a Mapkit still be accepted in the contest? Another question! Are essays required this year? I don't see it in the requirements.

Hello, Sometimes I need to send a message via sendMessageToProvider to tell the proxy service in NetworkExtension that it should be restarted It looks like this: self.sendMessageToProvider("restart"...) { resp if resp != "ok" { // stopVPNTunnel()... } } Then accept the request in NetworkExtension, which looks like: open override func handleAppMessage(_ messageData: Data, completionHandler: ((Data?) -> Void)?) { reasserting = true setTunnelNetworkSettings(nil) { error in startTunnel() { reasserting = false completionHandler("ok"...) } } } But NetworkExtension crashes occasionally and I spent a long time looking for the cause but found nothing. Where should I start?

On iOS 16 (16.4 specifically) and not iOS 17, I am running into an issue where navigationPath in MyNavigationViewModel is cleared when my app is backgrounded. I seemingly couldn't find much discussion around this happening. I'm hoping there is a work around and this is not intended, as the larger project I am working on depends on the state of navigationPath persisting despite being backgrounded. Note: Since I am working on a larger project, so I'm trying to mimic it's structure, which is why I am doing things like passing my view model as an environment object, and having a button in the side bar to push the initial view on to the navigation destination. To reproduce and observe the issue using the sample code below: Swipe from the left edge of the screen to open the side bar (not sure why applying the .balanced style is not having the sidebar displace the detail view, but that's a separate issue I'm not concerned about...) Click the button "Present Detail View" Background the app Wait some time (you will be able to see the print statement in the didSet print out a count of 0 for navigationPath) Reopen the app Observe the Base detail view is displayed, as opposed to the view that was pushed by pressing the side bar button. The navigation path was cleared. Any advice on how to deal with this issue? public class MyNavigationViewModel: ObservableObject { @Published var navigationPath: [MyType] = [] { didSet { print("Count: \(self.navigationPath.count)") } } } public struct MyType: Hashable { public var string: String } public struct MyDestination: View { @EnvironmentObject var viewModel: MyNavigationViewModel var text: String let onBackPressed: ()->() let onNextPressed: ()->() public var body: some View { VStack { HStack { Button(action: { self.onBackPressed() }, label: {Text("Back")}) Button(action: { self.onNextPressed() }, label: {Text("Next")}) } Text("String: \(self.text).") } } } @available(iOS 16.0, *) public struct MyNavigationView: View { @EnvironmentObject var viewModel: MyNavigationViewModel public var body: some View { NavigationSplitView( sidebar: { VStack { Button( action: { self.$viewModel.navigationPath.wrappedValue.append(MyType(string: "Hello")) }, label: { Text("Present Detail View") } ) } }, detail: { NavigationStack(path: self.$viewModel.navigationPath) { Group { Text("This is the detail base view.") } .navigationDestination(for: MyType.self) { data in MyDestination ( text: data.string, onBackPressed: { if(self.$viewModel.navigationPath.wrappedValue.count > 0) { self.$viewModel.navigationPath.wrappedValue.removeLast() } }, onNextPressed: { self.$viewModel.navigationPath.wrappedValue.append(MyType(string: "This is the next thing")) } ) } } } ) .navigationSplitViewStyle(.balanced) .environmentObject(self.viewModel) } } @available(iOS 16.0, *) struct ContentView: View { var body: some View { MyNavigationView().environmentObject(MyNavigationViewModel()) } } @available(iOS 16.0, *) struct ContentView_Previews: PreviewProvider { static var previews: some View { ContentView() } }

I want to import a csv-file to my app. It works when I use the Simulator but when I try to import the same file on my iPad, the follwowing message occurs: UserInfo={NSFilePath=/private/var/mobile/Containers/Shared/AppGroup/4C49BACA-5490-45A4-A8DF-6D47711CFC34/File Provider Storage/LUSD 3.csv, NSUnderlyingError=0x2812068e0 {Error Domain=NSPOSIXErrorDomain Code=1 "Operation not permitted"}}. Where do I find the right settings to enable the import of this csv-file?

I've put together a somewhat simple app to demonstrate drag and drop using .draggable and .dropDestination. I'm using a simple custom object with two strings and two enums as properties. I have followed all the steps for UTType and implementing Transferrable. I have two views displayed from the ContentView. The left side is a List with four of my custom objects (a user). The user is a "card" I implemented in a separate imbedded view. The right side is a drop area which is a ZStack with a List inside which displays an array of users dropped onto the ZStack. The draggable seems to be working fine. I can drag a user "card" around. The drop doesn't work. I have the .dropDestination on the ZStack and the initial closure on the .dropDestination doesn't seem to fire. I placed a print() in both closures and the print() in the first closure never prints. The "isTargeted:" closure does fire (a little unreliably) on the iPhone simulator and (less reliably) on the iPad.

I updated my iPad to the 17.1.1 update and there is a problem with my Files. I have pdfs that I read there and every time I open a pdf and want to make notes, the Files app crashes. I have restarted the device numerous times and still the same. None of my notes are saved on the pdf and then the Files crashes again and again and again. Why is this happening? I'm doing important work on the Files and I can't now with this update. Also before the update I had the opportunity to move the pdf to another folder while reading it and move to other pdfs left and right but with the new update this possibilities are gone. I have to close the pdf file and move it to another folder or close the file and scroll through the folder to find other files that I want. How can I fix this? This didn't happen before the update.

Hey there, in order to comply with the German law, especially the KassenSichV for cash register systems it is necessary to access the "manufacturer issued unique device serial number" and log it in the sales history, as well as print it on the receipt for the customer. Is there any way to access the device serial number through .NET Maui, or even Swift? Thank you in advance!

We are in the midst of testing camera and photo/video access using iPadPro 17 Beta (21A5326a) from within our application, and we are encountering an error message on only one device (iPad Pro 12.9-inch, A2229). Full access to the camera roll has been explicitly granted to the application when prompted. On only the above device, attempting to select an existing photo results in this error popup: "Photo or Video Unavailable: This app is using the Photos picker in an unsupported configuration." (We are able to take and save new photos from within our application on this device with no issues.) I have a second device on hand (iPadPro 10.5-inch, A1701) that presently also has the same iPadOS version installed and is running the same application, and we are able to select existing photos and take new photos with no errors. I have compared the Photos settings on both devices, and they appear to be identical. On a third iPad device running with the same iPadOS version, application, and Photos settings (that device is not in my possession), it has been reported that no errors are encountered when either taking new photos or selecting existing photos via the Photo Picker from within our app. We are trying to figure out what might be causing this error to appear when selecting existing photos on only the A2229 device, and/or what aspect of the configuration or settings would need to be modified in order to use the photo picker on that one iPad Pro. This issue had not been encountered on the A229 device while running with iPadOS 16. Searching the text of this error message online has not returned anything significantly meaningful thus far.

Hi all, I'm looking for the specifications for the accelerometers used in current iPhone and iPad devices, including the sensitivity and the update rates possible. Despite the documentation saying it's 100Hz, I've not yet found it to be better than 50Hz on any of iPhone SE, 8 or 11, nor iPad mini or Pros. Any help would be much appreciated! A
