QuickLook | Bring macOS “ Quick Look ” feature to Windows | Command Line Interface library

I have a Reality Composer file with several scenes, all of which starts empty and then some models appear one by one every second. Even though the animation works perfectly in Quicklook and Reality Composer, it does a strange glitch when I try to integrate it in my app with Xcode. When the very first scene is launched or when we go to another scene, they don't start empty.. For a tiny split second, we see all the models of that scene being displayed, only to disappear immediately.

Then, we see them appearing slowly as they were supposed to. That tiny flash of models at the beginning of each scene is ruining everything. I tried using a .reality file and a .rcproject file, same problem. In fact, when we preview the animation of the Reality file inside Xcode, it does the same glitch. I tried using different Hide and Show functions, no change.. I tried different triggers such as notifications, scene start, on tap, no change.

I checked quite some tutorials and still couldn't find anything wrong in what I'm doing. I almost feel like there is a glitch in the current integration of Reality Composer. I would really appreciate some ideas on the subject...

I have a SwiftUI iOS app that I have made available for mac catalyst. I am using QuickLook Preview to dispaly pdf, docx, images and pptx in the app. The rendering works fine on iOS but on MacOS, only 1 page of the document is displayed with a blurry look.

Here is my code that implements the QuickLook:

Capturing an image of an off-screen window with CGWindowListCreateImage is a common way to create QuickLook style zoom-in animations, but this seems create an image with the wrong background colour, slightly lighter than the real window.

This causes a flash at the end of the animation which kind of ruins the effect.

Does anyone have any idea why this happens and what can be done about it?

EDIT: I created a demonstration app for this problem. It is a bit large and complex for a Stack Overflow question, but the relevant code is probably in the ZoomingWindow.m methods takeSnapshot and makeAndPrepareSnapshotWindow.

A have a hand full of .avi files which I would like to convert to .mp4. Cobbling together everything I have found on the Internet, I end up with something like this:

I have an Ionic 5/Angular iOS app which builds fine as a non-production build and runs on both emulator and device as a dev build.

When I come to build it as a production build using:

ionic cordova build --prod --device

I use the ionic cordova build --prod command with the --device param to build the final IPA.

The app bundle Archive succeeds (so I can get an APP file), but the final stage fails with:

Error Domain=IDEProvisioningErrorDomain Code=9 ""blah.app" requires a provisioning profile with the Associated Domains feature." UserInfo={IDEDistributionIssueSeverity=3, NSLocalizedDescription="blah.app" requires a provisioning profile with the Associated Domains feature., NSLocalizedRecoverySuggestion=Add a profile to the "provisioningProfiles" dictionary in your Export Options property list.}

However, the identifier for the app has the associated domains entitlement selected and the provisioning profile in Xcode confirms this. Even a quick-look on the file itself shows the entitlement to be present:

I've searched for help with this, but there appears to be nothing specifically like this, where a build is failing because the system says an entitlement isn't there, when it actually is.

I've tried redoing all of the signing from scratch, to no avail.

Has anyone seen/fixed this before, and if so, what did you do? Tearing my hair out.

I'm using QLPreviewController to show AR content. With the newer iPhones with LIDAR it seems that object occlusion is enabled by default.

Is there any way to disable object occlusion in the QLVideoController without having to build a custom ARKit view controller? Since my models are quite large (life-size buildings), they seem to disappear or get cut off at the end.

I have soup. I want to extract all rows containing these three required information.

How can I do it?

I am writing a QuickLook plugin for macOS and everything works, except that I can't set programmatically the window size of the preview.

It starts with 800x600, no matter what I do in the XIB and/or in the code, before and/or after the call to the completionHandler of preparePreviewOfFile.

Other file types, handled by the default plugin, adapts the preview window size to the content of the file. I would like to do just that.

The preview window is resizable by the user and, once resized, keeps the new size when I select another file in the Finder, to go back to 800x600 if I close it and reopen it on a file handled by my plugin.

What am I missing?

Following the answer here: Set QuickLook window size when previewing with QLPreviewingController.preparePreviewOfFile I set the preferredContentSize of the QLPreviewingController, which changes the window size as intended, but this seems to break subsequent auto resizing of all subviews. After setting it, the content will no longer track the preview window size when the user resizes it manually or enters fullscreen.

Any attempts to set view sizes, resizing masks or constraints programmatically after setting the preferredContentSize property will cause errors like
