Does anyone know why the following call fails? CGPDFOperatorTableSetCallback(operatorTable, "ID", &callback); The PDF specification seems to indicate that ID is an operator? BTW what is the proper topic/subtopic for questions about Quartz? Wasn't sure what topic on the new forums to post this under.

I recently found the tinted app icon feature, which I love I think it is such a cool idea. The execution on the other hand is slightly flawed, I tried to set my apps to the light pink color. The feature work well in the editing area but once I clicked done the apps went from a light pink to dark red. I have tried this multiple times with multiple colors and the issues are consistent through all colors except when using the color dropper.

Hello, I'm new here, I was developing a screen recording extension for an IOS application, I used the RPSBroadcastSampleHandler livekit as a basis, in tests a few months ago it worked, but after the long wait for publishing authorization the extension stopped working, I noticed which is not just mine but screen sharing from Google Meet, Zoom Mettings and others also don't work, I tested it on iPhone 14 pro and iPhone 6s, nothing worked, the option to select the extension appears but when clicking "start sharing" nothing happens and after a few seconds the sharing button returns to "start sharing", the same behavior in all tested apps, does anyone know what happens? Did you change the way you record and no app has updated? Internal error in IOS? Nothing logs in terminal just doesn't work.

We are building our own Cocoapod file. We have to convert a local DOC file to PDF with any server interaction. It will be in offline mode. Any suggestion will be appreciated.

Hi, I've been implementing a tabletop game over the last couple of weeks. One thing that I'm struggling with it getting an EntityEquipment to render. I've followed the instructions in the documentation: https://developer.apple.com/documentation/tabletopkit/entityequipment But still no luck. Any insights what I might be missing are highly appreciated. Note: I've also watched the WWDC24 talk https://developer.apple.com/videos/play/wwdc2024/10091/ several times and downloaded the example but while the pawns render in the example perfectly. In my own implementation of a pawn nothing renders.

The application that I'm working on uses WebKit. I'm facing a strange behavior in the app with MACOS14.5, in which errors are being reported only for this OS version.

I have worked through the LearnMetalCPP project but it seems that even with the port of AppKit.h to C++ framework, nobody included a method to gain keyboard and mouse inputs in C++. I am under the impression AppKit had a way to manage events with NSEvent and NSResponder, as it mentions in the developer documentation for gaming input systems, but this is excluded from the CPP version of Appkit.h. Can't seem to find a way to handle inputs at all and it's making it seem impossible for anyone to successfully make a game on MacOS in C++. Usually I would be able to handle it with SFML or SDL, but I am wondering since c++ isn't native to macOS if there is any possible way to handle game inputs with C++ at all. It is Apple's hardware, shouldn't they be the ones to create a C++ game input framework? They seem to have a game input framework for every language except for C++. I would understand that they just don't want to do it because C++ isn't native to macOS, but with the new release of Metal CPP, It makes no sense that they wouldn't include a hardware input event system and especially if they want us to port games to MacOS.

I have a macos app that creates a sports scoreboard and streams this out in a third party streaming format. I need to use a library for this, which expects a CVPixelBuffer e.g. every 0.04 secs (25 fps). The scoreboard is a view with some subviews (scores, timers, etc) in an offscreen window. When a timer triggers to create a new frame, my code does: • create a bitmap-representation for the view • make a view.cacheDisplay(...) • create a CIImage from the bitmap-representation • create a CVPixelBuffer using CVPixelBufferCreate (kCVPixelFormatType_32BGRA format) • render the CIImage into the CVPixelBuffer using ciContext.render(ciImage, to: pixelBufferOut) • and finally hand over the CVPixelBuffer to the video library. Works, the app is in production. Now I come to the point where I need someone to tell me in which direction I have to think. The next feature requested is to do some animation for the scoreboard graphics , e.g. a simple "fade in" and "fade out". Later I would like to do more complex things, but let's just look at that. When I add a CABasicAnimation(keyPath: #keyPath(CALayer.opacity)) for fade in / fade out to the scoreboard base view (all views with layer), I can see it smoothly fading after I moved my offscreen to onscreen, so the animation works on screen. But in the video stream there is no animation, no fading, the content is shown with opacity 0.0 at one frame and in the next frame 1.0 (fade in) and the other way round for fade out. I have a not-animated, always visible text field displaying a timecode in the video screen and that shows every timecode in the video, so the frames are in fact generated, but contains no scoreboard view with an opacity other than 0 or 1. How can I get the rendered frames from an animation? Is it somehow possible with Core Animation? Do I have to dig into Metal? I searched for hours to find something, but "animation" leads to discussions about animations on screen, while "video" is always about AVFoundation, but there is this library I have to use. Thanks for any hints, Nina

Hi, I'm having a small App in the AppleTV-Simulator which is supposed to use the Siri-Remotes Swipe-Gesture. It works perfect on the real device but on the simulator the Swipe-Gesture is not recognized in the App but it works on the Start-Screen of the Simulator using the simulated Siri-Remote app. Here is the code which sets up the xAxis ans yAxis value change handlers: #if targetEnvironment(simulator) // Simulator let siriRemote = GCController.controllers().filter { controller in if controller.vendorName == "Gamepad" { return true } else { return false } } let sController = siriRemote.first! let inputProfile = sController.physicalInputProfile let dPad = inputProfile.dpads["Direction Pad"] self.dPad = dPad self.dPad!.xAxis.valueChangedHandler = self.directionPadXAxisValueChangeHandler self.dPad!.yAxis.valueChangedHandler = self.directionPadYAxisValueChangeHandler } #else // Device if let _ = ( notification.object as? GCController)?.microGamepad { let microProfileController = notification.object as! GCController self.microGamePad = microProfileController.microGamepad self.dPad = self.microGamePad!.dpad self.dPad!.xAxis.valueChangedHandler = self.directionPadXAxisValueChangeHandler self.dPad!.yAxis.valueChangedHandler = self.directionPadYAxisValueChangeHandler } #endif Any help is greatly appreciated. Cheers, Frank

A sample of some error messages that are presented in the Xcode log for executon of a program. There is nothing in the messages that will help identify a component as the origin of the message, nor is there a locatable derinition for the various labels and fields of the text. What component or even framework does this set of messages originate? Your search engine is useless because it returns gibberish. It doesn’t even follow the common behavior of SEARCH ENGINES because it takes label strings compounded from common words and searches for the common word instead of using the catenated string that is the internal variable name that is in the text. 2024-06-22 19:45:58.089943-0500 RoomPlanExampleApp[733:30145] [ClientDonation] (+[PPSClientDonation isRegisteredSubsystem:category:]) Permission denied: GenerativeFunctionMetrics / ANEInferenceOperationPrepareForEncode.

If anyone even uses this, GCVirtualController from import GameController no longer plays nice with SwiftUI NavigationView Working on changes to get by... This was working in iOS 17.x but not in iOS 18 and iPadOS 18. Just a heads up...

Recently started playing this game, when I restarted my computer once it glitched out and when I tried to open it again, it said "last time you opened this app, it was force quit. Do you want to reopen it?" then the app closes itself immediately. How can I fix this? How can I remove the caches?

Does GPTK2 support all AVX instructions like F16C, or only AVX2?

My app isn’t a game app, but iOS 18 always enable Game Mode for my app automatically. I didn’t find a switch to disable it in Xcode.

when i open settings on my phone, i cant see game mode settings i work as a game tester in game company and i need more information about the game mode

Hello, I have a USDC file with vertex color (WITHOUT textures), and it displays perfectly in Preview. If I package it in a zip (without compression) and rename the resulting file to USDZ, I can see it without any issues in AVP and Mac. However, if I send it to an iPhone, the vertex color does not display. Is there anything else I need to do besides packaging the USDC without compression in a ZIP? Thank you very much.

Hey, Just watched and started investigating a new TabletopKit framework, which looks fantastic. I'm looking at how multiplayer can be tested. Found info about testing on multiple real devices here - https://developer.apple.com/documentation/tabletopkit/tabletopkitsample#Start-a-multiplayer-game-on-devices I wanted to ask about options for testing multiplayer on simulators, maybe with a simulator + a single real device. Unfortunately, having multiple VisionPros for indie development is unrealistic, so I hope there are ways to do it.
