I am creating an iOS app to install on legacy iPads running iOS 9 and up, using XCode 13.4.1 which is the latest version that will support iOS below 11. The app is working fine but I just added a QuickLook Preview extension, and on iOS 10.3.1 it will not install due to the following error: This app contains an app extension that specifies an extension point identifier that is not supported on this version of iOS for the value of the NSExtensionPointIdentifier key in its Info.plist. Domain: com.apple.dt.MobileDeviceErrorDomain Code: -402653007 The NSExtensionPointIdentifier key in Info.plist is set by XCode automatically to "com.apple.quicklook.preview". I want to set the iOS Deployment Target to the lowest iOS version that will support this configuration. The documentation does not provide any guide as to which specific NSExtensionPointIdentifier keys are compatible with which iOS version. It just says 8+ for the whole list. Trial-and-error is limited by availability of legacy Simulators. If anyone can point to documentation that indicates which iOS is supported by which NSExtensionPointIdentifier key com.apple.quicklook.preview, I would be very grateful. Thanks (I understand about lack of App Store support etc, this is an app for my use on old iPads)

I created a project using Reality Composer Pro. When I export to a .usdz file, it works well on iPhone 13, 14, 15, and 16 but not on iPhone 12 and 11. In the timeline, I use a behaviour that is on added to scene to active intro animation and loop background audio. But it does not work on old device like iPhone 12 and 11. Also, all interactive taps/touch points/audio don't seem to work too. Iphone 13,14,15,16 is on ios 18.1. iPhone 11, 12 is on ios 17.6.1. Here is sample usdz file exported from REality Composer Pro 2.0 that has problem above: https://drive.google.com/file/d/1sHZn9JABTswLq2flYjToTbWDuE5T7eNw/view?usp=sharing

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.

We have a native iOS app that supports the upload and display of USDZ files. It has been working great since beta (late 2022) and live launch (late 2023) until now. But recently we had reports from some users on Max model phones (14 + 15 Pro Max) at least. When they launch tap and launch a 3D file the Quick Look player is triggered. So far so good. But for affected users the controls along the top of the player - X (close) AR | Object (toggle) and share button - are moving too high up the phone screen and getting stuck (untappable) behind the phone's top status bar (time, camera bug, connection, battery). This means that when they open a USDZ file in AR or 3D view they have to hard-close the app to get out of it again. This doesn't happen when they open a USDZ file from Files, Dropbox etc on their phone (which also uses the Quick Look player). The controls only move up and get stuck when launching a USDZ from within our app. I'm at a loss to figure out what might be causing this on some phones and not all others. And why only when opening a USDZ file from our app! So far we have replicated this issue on a single iphone 14 Pro Max and a 15Pro Max, both running iOS18+ We have tested on other 15Pro Max's on same OS, and Pros, normal iPhones, Minis and are not experiencing the issue. You would think that a USDZ file is a USDZ file and that your iPhone knows what to do with it and open it in the Quick Look player regardless of where you open the file from. Why would the navigation items be moving if you open the USDZ file from within our app, and why only for some select users? We will continue to troubleshoot and test but I wanted to throw this out to the community in case anyone had experienced this or if anyone had any theories that would expedite our testing. Your thoughts are most appeciated! Here is a video showing the expected (correct) behaviour: https://www.dropbox.com/scl/fi/0sp8s4opaf2m4gukkcbrk/How-opening-a-USDZ-should-behave_correct-behaviour.MP4?rlkey=tzzau9x91mwox66gsgguryhep&st=qiykmne9&dl=0 and a screenSHOT attached below of what is happening on one of the affected user's iPhone 15Pro Max.

Hi, I'm using NSPanel that his level is .popUpMenu and when I use .quickLookPreview in SwiftUI it make the the Quick Look behind the nspanel how can I fix it without change the level of NSPanel?

Below iOS, 18.0 its working properly but in iOS 18.0 facing issue I can download pdf , I can see downloaded pdf in app sandbox container but unable to preview with app

I"m trying to create a simple app for my students that will display .heic images taken with a nikon and them converted to .heic in the photos app. My attempts only result in the QuickLook viewer showing the images in 2d. Any guidance? Here is my ContentView: import SwiftUI import QuickLook struct ContentView: View { @State private var showQuickLook = false @State private var previewURL: URL? = nil // State to store the URL for Quick Look var body: some View { VStack { Button("See it in 3D") { // Set the URL for the file from the bundle and toggle Quick Look presentation if let imageURL = Bundle.main.url(forResource: "Michelia_fuego", withExtension: "heic") { previewURL = imageURL // Set the preview URL if the image is found showQuickLook.toggle() // Toggle to trigger Quick Look presentation } else { print("File not found") // Print error if the file is missing } } .quickLookPreview($previewURL) // Binding to the URL } } } #Preview { ContentView() }

Hi, Following the wwdc24 video - What’s new in Quick Look for visionOS, I've managed to open a 3D model using PreviewApplication by calling let previewItem = PreviewItem(url: modelURL, displayName: "Easter", editingMode: .disabled) _ = PreviewApplication.open(items: [previewItem]) However, the "Save to Downloads" option is aways there(see attached screenshot). As the models are user generated content, and I don't want the download option to be available to all users. How to disable it?

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,

Apple's own USDZ files from their website does not display properly both in OPReview and in Keynote when imported. It displays properly, however, in Reality Converter bit with this error: "Invalid USD shader node in USD file Shader nodes must have “id” as the implementationSource, with id values that begin with “Usd”. Also, shader inputs with connections must each have a single, valid connection source." I tried importing other models from external sources and they work without any issue at all. Is there any potential fix or workaround this? Thanks in advance.

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. 🙏

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.

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.

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.

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?

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.
