I'm experiencing an issue with QuickLook in iOS 18 where.reality files with audio playback are affected. When I open a.reality file that includes audio, the audio track plays twice: once from the moment the file is opened, and again from the start of the animation. This results in a duplicate audio playback. I've tested this issue on multiple devices running iOS 16, 17, and 18, and the problem only occurs on iOS 18. I've tried restarting the devices and checking for any software updates, but the issue persists. Steps to reproduce: Open a.reality file with audio playback in QuickLook on an iOS 18 device. Observe the audio playback. Expected result: The audio track should play only once, from the start of the animation. Actual result: The audio track plays twice, once from the moment the file is opened and again from the start of the animation. Device and iOS version: I've tested this issue on iPhone 12 Pro, iPhone 13 Pro running iOS 18, iPhone 13 running iOS 16 and iPhone 11 Pro running iOS 17,

QLPreviewView was used in the app to display the file previews. But the following crash was happening.

Have the requirements to support swipe to dismiss from a quick-look view controller changed in iOS18? I am noticing that my app no longer supports gestural dismissal in an iOS18 build. Not this is a QLPreviewController presented from a UIViewController presented in a SwiftUI view hierarchy as part of a ViewControllerRepresentable.

On iOS17, when the device is on Dark mode, the background of the Edit Mode in QLPreviewController has white color, instead of dark color. (like in the iOS18 betas) We support both iOS17 and iOS18 and we want our users to have a consistent experience, so we think this should be aligned in iOS17, as it's currently working in iOS18 betas. Steps: Set the device to Dark Mode. Present a QLPreviewController and preview an image. Enable Markup/Edit mode. Observe the image background Actual Result: The background is in white color. Expected Result: The background is in dark color. (Just like in iOS18 betas) Xcode 16b3, All iPhones.

This question is about USD animations playing correctly in macOS Preview but not with RealityKit on visionOS. I have a USD file created with 3D Studio Max that contains mesh-based smoke animation: https://drive.google.com/file/d/1L7Jophgvw0u0USSv-_0fPGuCuJtapmzo/view (5.6 MB) Apple's macOS 14.5 Preview app is able to play the animation correctly: However, when a visionOS app uses RealityKit to load that same USD file in visionOS 2.0 beta 4, built with 16.0 beta 3 (16A5202i), and Entity/playAnimation is called, the animation does not play as expected: This same app is able to successfully play animation of a hierarchy of solid objects read from a different USD file. When I inspect the RealityKit entities loaded from the USD file, the ground plane entity is a ModelEntity, as expected, but the smoke entity type is Entity, with no associated geometry. Why is it that macOS Preview can play the animation in the file, but RealityKit cannot? Thank you for considering this question.

When I launch the Quick Look Preview Extension target in Xcode, an app called Quick Look Simulator opens with an almost empty window: Online I read that the Terminal command qlmanage allows to test Quick Look plugins (which I think were an older format for creating Quick Look extensions), but running qlmanage -p /path/to/previewed/file -c public.text -g /path/to/QuickLookPreviewExtension.appex (where QuickLookPreviewExtension.appex is generated by the Xcode build and is located in the DerivedData folder) gives an error Can't get generator at QuickLookPreviewExtension.appex How can I debug a Quick Look Preview Extension?

Hello everyone I am looking to build a simple app for displaying a spatial video using the quick look preview API. I have been following this video which is useful: https://developer.apple.com/videos/play/wwdc2024/10166/#:~:text=QuickLook%20is%20the%20system%20standard,just%20like%20the%20Photos%20app. I am new to building apps in Xcode, and I could do with some advice on how to build the rest of the project mentioned in the above video. I was wondering if there is source code or a project example available anywhere for an app the uses the Quick Look preview API?

When opening the 3D model in Augmented Reality on Safari, the model initially displays correctly. However, when attempting to move, resize, or rotate it, the device screen freezes along with the Augmented Reality view, and sometimes it crashes the application. This same model does not have any issues when opened in Chrome. Has anyone experienced something similar, and if so, do you know how to resolve it?

QLPreviewController's PencilKit doesn't get mirrored when used with a RTL language in iOS18b3. Moreover, the sub-menu of the actions is not translated and is shown in English. Steps to reproduce: Set an app with QLPreviewController and set its app language to Hebrew (or any other RTL language) Run the app Tap the Markup button on bottom-left side. Look on the PencilKit element. Tap the + button to show the annotation actions. Look on the annotation actions menu. Current: The Pencil Kit element is not mirrored when app language is RTL Language and the sub-menu actions are shown in English. Expected: The Pencil Kit element is mirrored when app language is RTL Language and the sub-menu actions are shown in the RTL Language. Submitted Feedback: FB14452847 Notes: This wasn't reproducible in iOS 17.5.1 The top bar buttons are mirrored as expected with a RTL language.

Hi, I have a Spatial Video that I am trying to load in a visionOS app with PreviewApplication API let url = URL(string: "https://mauiman.azureedge.net/videos/SpatialJourney/watermelon_cat.MOV") let item = PreviewItem(url: url!) _ = PreviewApplication.open(items: [item]) When I run the application, I am getting the following error. Did I miss anything? QLUbiquitousItemFetcher: <QLUbiquitousItemFetcher: 0x6000022edfe0> could not create sandbox wrapper.

There seem to be a regression in QLPreviewController with iOS17, since it works in both iOS16(latest) and iOS18b3. After following the steps (described below), using iOS17.X the QLPreviewController gets frozen up so all of it's top buttons are no tappable, although you can still draw on the canvas. Steps to reproduce: Setup QLPreviewController to preview a single image in png format. The QLPreviewController should be presented as the rootViewController of a UINavigationController. Present the UINavigationController that has the QLPreviewController as its rootViewController. Tap the Markup button. Pick the leftest tool from the PencilKit tools at the bottom. Draw a curvy long line from the bottom-right corner of the canvas, to the top-left corner of the canvas. Tap any of the top buttons. Current: The top buttons are not tappable. Expected: The top buttons are tappable. Any idea how to workaround/fix this issue? Notes: The issue seems to be reproducible in iOS17, and isn't reproducible in iOS16 or iOS18b3 using Xcode 15.4 and Xcode 16b3. The issue is reproducible in both iOS17 Simulator or devices. The issue is reproducible in both UIKit and SwiftUI. Possible same issue was mentioned here: https://stackoverflow.com/questions/78090416/navigation-toolbar-buttons-stop-working-after-keyboard-is-shown-on-ios-17-sw I couldn't attach a sample project to here due to file format limitation, but you can use the project from this repository and use a png instead of a pdf: https://github.com/NilCoalescing/SwiftUI-Code-Examples/tree/main/QuickLook/SwiftUIQuickLookInUINavigationController (code by Natalia Panferova) Attached is the image of the drawing done in iOS17.5 Simulator.

I'm having a problem where any buttons won't be shown when displaying a QLPreviewController with swift. With .quickLookPreview() these buttons are shown, including share, done, annotation etcetera. The buttons are not shown when using QLPreviewController with SwiftUI, however if used with other UIKit they are shown. How to fix this? I'm not really looking forward in implementing all of the annotation functions and other QuickLook capabilities again. The ultimate goal of mine is to allow annotation and other pdf editing with the ability to save the file via the Done button, but on .quickLookPreview() the Done button displays "Save to files" and "Discard" and on QLPreviewController the button is not shown. The issue has been addressed on several forums, yet a solution has not been found. Reproducement in nutshell: new QLPreviewController conforming to UIViewControllerRepresentable display the QLPreviewController in SwiftUI view Thanks.

QLPreview keeps blinking and stops previewing the file when opening some high-resolution PDF files with heavy content. This can only be simulated in a real device built in xcode simulators cant simulate the issue. Tested in Xcode Version 15.4 (15F31d) and iPadOS Version 17.5.1. Following is My Sample code : import UIKit import QuickLook class ViewController: UIViewController { var currentViewFilePath = "" let preview = QLPreviewController() override func viewDidLoad() { super.viewDidLoad() self.setupQLPreview() loaddata() // Do any additional setup after loading the view. } func loaddata(){ if let fileURL = Bundle.main.url(forResource: "CD28048D", withExtension: "pdf") { self.currentViewFilePath = fileURL.relativePath self.preview.reloadData() // Use the fileURL here print("File URL: \(fileURL)") } else { print("File not found") } } } extension ViewController:QLPreviewControllerDelegate,QLPreviewControllerDataSource{ func setupQLPreview(){ preview.delegate = self preview.dataSource = self self.view.addSubview(preview.view) let previewhight = (UIScreen.main.bounds.height - ((self.navigationController?.navigationBar.frame.height ?? 0))) preview.view.translatesAutoresizingMaskIntoConstraints = false preview.view.topAnchor.constraint(equalTo: self.view.topAnchor).isActive = true preview.view.leftAnchor.constraint(equalTo: self.view.leftAnchor,constant: 4).isActive = true preview.view.rightAnchor.constraint(equalTo: self.view.rightAnchor,constant: -4).isActive = true preview.view.leadingAnchor.constraint(equalTo: self.view.leadingAnchor,constant: 4).isActive = true preview.view.trailingAnchor.constraint(equalTo: self.view.trailingAnchor,constant: -4).isActive = true preview.view.widthAnchor.constraint(equalToConstant: self.view.frame.width-8).isActive = true preview.view.heightAnchor.constraint(equalToConstant: previewhight-4).isActive = true preview.view.bottomAnchor.constraint(equalTo: self.view.bottomAnchor).isActive = true preview.navigationController?.isNavigationBarHidden = true self.addChild(preview) preview.didMove(toParent: self) } func numberOfPreviewItems(in controller: QLPreviewController) -> Int { if self.currentViewFilePath.isEmpty || self.currentViewFilePath == ""{ return 0 }else{ return 1 } } func previewController(_ controller: QLPreviewController, previewItemAt index: Int) -> QLPreviewItem { let fileUrl = URL(fileURLWithPath: self.currentViewFilePath) return fileUrl as QLPreviewItem } } while running the above code Xcode debugger prints following errors: View service did terminate with error: Error Domain=_UIViewServiceInterfaceErrorDomain Code=3 "(null)" UserInfo={Message=Service Connection Interrupted} #Remote Preview collection viewServiceDidTerminateWithError: Error Domain=_UIViewServiceInterfaceErrorDomain Code=3 "(null)" UserInfo={Message=Service Connection Interrupted} #Remote [u 0AA9D4C5-BBA1-56F6-8FFF-F5F56B99399A:m (null)] [com.apple.quicklook.extension.previewUI(1.0)] Connection to plugin invalidated while in use.

I'm stuck on a problem where I need to be able to have the same editing capabilities as in .quickLookPreview and be able to save the edited file to the application with the "Done" button. So, in nutshell, I need to implement the same functionality many other applications provide including Apple's Files. However with .quickLookPreview I don't get the ability to save edited files directly to the application, and I've had no luck finding help from the internet (thus this question). Perhaps somebody has implemented this before and could give me a lead somewhere? PS. I'm trying to find a solution without any third party libraries

I'm developing an application in which saving files and opening them with .quickLookis in important role. However, after putting my application to TestFlight and letting a friend of mine test it with his phone (iOS 17.4.1, iPhone 15 Pro) it appears that sometimes when opening a file the QuickLook sheet doesn't open until the app's focus is lost. @State Button("Open file") { url = someFileUrl }.quickLookPreview($url)

this week i was watching https://developer.apple.com/videos/play/wwdc2024/10105/ with the amazing "configuration" feature to change the color or mesh straight in quick look, but i tried a lot with goarounds but nothing bring me to success how do i write in the usda files? anytiome i overwrite the usda even with just a "{}" inside... Reality composer pro rejects the file to be open again where is the developer man in the tutorial writing the usda? how is the usda compressed in usdz? (none of the compressors i tried accepeted the modified usda file) this is the code it's suggested in the video #usda 1.0 ( defaultPrim = "iPhone" ) def Xform "iPhone" ( variants = { string Color = "Black_Titanium" } prepend variantSets = ["Color"] ) { variantSet "Color" = { "Black_Titanium" { } "Blue_Titanium" { } "Natural_Titanium" { } "White_Titanium" { } } } but i dont understand how to do it with my own files,

It is pretty cool that you can preview Spatial Photos and Videos with just PreviewApplication.push(...), but the issue is, you can disable the editing, but buttons to export content to Files still going to be there. So if my application uses this to showcase some proprietary or licensed content in my application, I cannot really disable an option of exporting it from my app. And another, more major issue, a lot of developers would not even know that user can save Previewed item, as this Save to Files button is not that easy to find.

We have QuickLook thumbnailing framework which is used to provide thumbnails for custom file types. However, how can we provide thumbnails for system defined file types for eg. image file types? Is there any way to achieve this?

Though I cannot find any documentation, it seems that UIPasteboard cannot be used from a Quick Look Preview app extension. I have such an extension, which contains a view that supports copying text as follows: - (IBAction)copy:(nullable id)sender { UIPasteboard * pboard = UIPasteboard.generalPasteboard; pboard.string = _rep.text; } This is invoked from a context menu (edit menu) item. This works fine In the simulator, but on device the pasteboard remains empty and errors like the following are emitted: -[PBServerConnection pasteboardWithName:createIfNeeded:authenticationBlock:dataOwnerBlock:error:] failed with error: Error Domain=NSCocoaErrorDomain Code=4099 "The connection to service named com.apple.pasteboard.pasted was invalidated: failed at lookup with error 159 - Sandbox restriction." UserInfo={NSDebugDescription=The connection to service named com.apple.pasteboard.pasted was invalidated: failed at lookup with error 159 - Sandbox restriction.} It's unclear to me why such functionality would be problematic and necessary to block. It would be nice if this were documented clearly, as I wasted a lot of time trying to figure out why this was not working. (And no, I have not filed a feedback report or TSI yet, as I'm presently very short on time, and I don't have a sample project prepared to demonstrate the issue.)
