Before iPadOS 18, I was using hidesBottomBarWhenPushed, and it worked beautifully. Now, it's broken/not working. How are we supposed to hide the new tab bar nowadays?

Hello! I'm getting crash reports in PHPickerViewController for iOS 17 users only.

My app needs to send iMessages with an attached data file. The view comes up modally and the user needs to press the send button. When the button is tapped the error occurs and the attachment and message is not delivered. I have tried three implementations of UIViewControllerRepresentable for MFMessageComposeViewController that have worked for iOS 15 and 16, but not 17. If I make the simplest app to show the problem, it will reliably fail on all iOS versions tested. If I remove the attachment, the message gets sent. In contrast, the equivalent UIViewControllerRepresentable for email works perfectly every time. After struggling for weeks to get it to work, I am beginning to believe this is a timing error in iOS. I have even tried unsuccessfully to include dispatch queue delays. Has anybody else written a swiftUI based app that can reliably attach a file to an iMessage send? UIViewControllerRepresentable: import SwiftUI import MessageUI import UniformTypeIdentifiers struct AttachmentData: Codable { var data:Data var mimeType:UTType var fileName:String } struct MessageView: UIViewControllerRepresentable { @Environment(\.presentationMode) var presentation @Binding var recipients:[String] @Binding var body: String @Binding var attachments:[AttachmentData] @Binding var result: Result<MessageComposeResult, Error>? func makeUIViewController(context: Context) -> MFMessageComposeViewController { let vc = MFMessageComposeViewController() print("canSendAttachments = \(MFMessageComposeViewController.canSendAttachments())") vc.recipients = recipients vc.body = body vc.messageComposeDelegate = context.coordinator for attachment in attachments { vc.addAttachmentData(attachment.data, typeIdentifier: attachment.mimeType.identifier, filename: attachment.fileName) } return vc } func updateUIViewController(_ uiViewController: MFMessageComposeViewController, context: Context) { } func makeCoordinator() -> Coordinator { return Coordinator(presentation: presentation, result: $result) } class Coordinator: NSObject, MFMessageComposeViewControllerDelegate { @Binding var presentation: PresentationMode @Binding var result: Result<MessageComposeResult, Error>? init(presentation: Binding<PresentationMode>, result: Binding<Result<MessageComposeResult, Error>?>) { _presentation = presentation _result = result } func messageComposeViewController(_ controller: MFMessageComposeViewController, didFinishWith result: MessageComposeResult) { defer { $presentation.wrappedValue.dismiss() } switch result { case .cancelled: print("Message cancelled") self.result = .success(result) case .sent: print("Message sent") self.result = .success(result) case .failed: print("Failed to send") self.result = .success(result) @unknown default: fatalError() } } } } SwiftUI interface: import SwiftUI import MessageUI struct ContentView: View { @State private var isShowingMessages = false @State private var recipients = ["4085551212"] @State private var message = "Hello from California" @State private var attachment = [AttachmentData(data: Data("it is not zip format, however iMessage won't allow the recipient to open it if extension is not a well-known extension, like .zip".utf8), mimeType: .zip, fileName: "test1.zip")] @State var result: Result<MessageComposeResult, Error>? = nil var body: some View { VStack { Button { isShowingMessages.toggle() } label: { Text("Show Messages") } .sheet(isPresented: $isShowingMessages) { MessageView(recipients: $recipients, body: $message, attachments: $attachment, result: $result) } .onChange(of: isShowingMessages) { newValue in if !isShowingMessages { switch result { case .success(let type): switch type { case .cancelled: print("canceled") break case .sent: print("sent") default: break } default: break } } } } } } #Preview { ContentView() }

I'm building a MacOS app which reads a lot of PDFs in the background. Some of these PDF's have an embedded font which is not installed on the system. In such cases the app shows a popup asking whether to Download or Skip the font. This seems to be a PDFKit behavior because I see the same behavior when I open the file in Preview (see screenshot) This behavior is disruptive to the user experience and I'd like to be able to disable font downloads. However I don't see any option in the PDFKit API to do so. Any ideas?

I have created an iOS 18 Control Center Widget that launches my app. However I am not able to detect it in AppDelegate.swift. I have created custom scheme funRun://beginRun in Target => Info => URL Types URL Types setup in Xcode This method in AppDelegate.swift does not fire at all and I get this error in console: Failed to open URL runFun://beginRun: Error Domain=NSOSStatusErrorDomain Code=-10814 "(null)" UserInfo={_LSLine=279, _LSFunction=-[_LSDOpenClient openURL:fileHandle:options:completionHandler:]}`` ` func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool { // this does not fire print("Scheme \(url.scheme)") print("Host \(url.host)") return true }` I tried this answer to no avail: iOS 18 Control Widget that opens a URL Even adding EnvironmentValues().openURL(url) as suggested here did not help. @MainActor func perform() async throws -> some IntentResult & OpensIntent { let url = URL(string: "funRun://beginRun")!

With the newest iPad Pro and iPad Air's, the front facing camera sits on the long horizontal edge, which is different from the previous version which had the camera on the shorter top edge. We have an app that needs to put a UI item near the camera. Is there a way of detecting where the front facing camera is on iOS? I have tried doing simple resolution checks, i.e, if width == ipadProWidth || width == ipadAirWidth { do2024iPadProLayout() } else { doStandardiPadLayout() } But this doesn't feel like the nicest way to do this check, because it's liable to break moving forward, and theres the possibility Apple release more devices with the camera on the horizontal edge. Any help here is appreciated!

Hi Is it possible to render webview in Widget? Basically i want to show some content of website in Widget on homescreen using webview. I tried to use WKWebview in WidgetView, but it's not rendering . Thanks with regards iOSProfessionals

We are trying to build a video recording app using AVFoundation and AVCaptureDevice. No custom settings are used like iso, exposure duration. All the settings are kept to auto. But when video is captured using front camera and 1080x1920 dimensions, the video captured from the app and front native camera does not match. In settings i have kept video setting as 30 fps 1080x1920. The video captured from the app includes more area than the native app. Also some values like iso, exposure duration does not match. So is there any way to capture video exactly same as native camera using AVFoundation and AVCaptureDevice. I have attached screenshots from video for reference. Native AVCapture

The documentation doesn't state how to get the new APNs push token that is associated with a Live Activity that is started via an APNs push notification. I have been able to get the new token by listening to all instances of the Live Activities for my attribute type, but it makes me wonder how the "input-push-token" option for iOS 18 is supposed to work. Is there another way to retrieve the newly created Live Activity push token when using "input-push-token"?

Hello, I am building a web app using Mapkit JS, and have something up an running where I can add markers and annotate places with Place ID (I followed along with the WWDC24 video). However occasionally, while I'm doing nothing on the browser, I get an runtime error with the following error trace (from developer tools in Chrome). === Uncaught TypeError: Cannot read properties of null (reading 'tint') at get tint (mapkit.core.annotations.d43c86.js:2:97102) at get colorScheme (mapkit.core.annotations.d43c86.js:2:81602) at e.exports.PlaceCardController._renderPlaceIframe (mapkit.core.map.536988.js:2:214785) at e.exports.PlaceCardController.update (mapkit.core.map.536988.js:2:212978) at e.exports.PlaceCardController._handleConfigChanged (mapkit.core.map.536988.js:2:213284) at _handleConfigChangedListener (mapkit.core.map.536988.js:2:212679) at n.dispatchEvent (mapkit.core.js:2:16624) at mapkit.core.js:2:10799 === It is completely random, and not a result of any browser / Map interaction.

Now that we are finally able to customize our home screen, can you disable the auto relocation feature? Making it extremely difficult to customize home screen when things are still moving around automatically. Thanks.

I have been using the QLPreviewController in an app for some time now and have always gotten a flurry of constraint warnings when it launches which I have ignored. I have looked at them and don't believe they are due to my code and the app seems to work.

I'm adding support for Genmoji to my app but it's unclear to me if this is something that should be called manually in code to insert an adaptive image glyph or if this is something that the system calls when the user inserts a Genmoji / adaptive image glyph object (ie. sticker) into the UITextView.

Hello everyone, I am using the new AccessorySetupKit, and whenever I try to remove an accessory I sometimes get an alert asking me to make sure if I want to remove the accessory from my device. The problem is that this alert sometimes shows up, and sometimes it does not. The removal of the accessory does work, it is just that the alert is not predictable. Is this expected behavior? How can we “predict” when it will show up and when it will not?

Is there a time limit for the perform method execution in iOS? I'm implementing App Intents that call an API from the perform method. Based on my testing, it works fine if the API completes within 10 seconds. However, if it takes longer, Siri ends the process with an error.

In the company that I work we have a huge app and we have implemented an image annotation feature using the QLPreviewController but there is a bug where even with an OOTB implementation of the QLPreviewController, when I add a text, change the colour of that text and then double click on the text to edit it, it reverts back to black. I tried the same implementation in a sample app but I couldn't reproduce the bug hence it is not a bug with the library but something with the app interacting with the library. I was wondering if anyone can provide any suggestion with what the reason may be, as sadly I cannot provide any code examples as that would break company code. From my research what I found strange is that when I double click the coloured text and it goes to black, then undo it its as if that was not a recorded event as the undo goes back to the step before the text was coloured meaning it replaces the colour changing event rather than recording it as a new event that can be undone. If any has any suggestion please help me as I am quite stuck. 🙏
