I tried to understand the view matrix. The part from original code as below: private func updateGameState() { /// Update any game state before rendering uniforms[0].projectionMatrix = projectionMatrix let rotationAxis = SIMD3<Float>(1, 1, 0) let modelMatrix = matrix4x4_rotation(radians: rotation, axis: rotationAxis) let viewMatrix = matrix4x4_translation(0.0, 0.0, -8.0) uniforms[0].modelViewMatrix = simd_mul(viewMatrix, modelMatrix) rotation += 0.01 } If the view matrix is initialed in x = -0.5, as:let viewMatrix = matrix4x4_translation(-0.5, 0.0, -8.0) The cube in the MetalView will move left. I think it should move to right hand side because View Matrix is camera position, am I wrong?

I have a 3х3 Matrix which I need to apply to UIImage and save it in Documents folder. I successfully converted the 3x3 Matrix (represented as [[Double]]) to CATrasform3D and then I have broken my head with trying to figure out how to apply it to UIImage. The only property where I can I apply it is UIView(or UIImageView in case with working with UIImage) transform property. But it has nothing to do with UIImage itself. I can't save the UIImage from transformed the UIImageView with all the transformations. And all the CoreGraphic methods (like concatenate for CGContext) only work with affine transformations which not suits for me. Please give me a hint what direction I should look. Does Apple has native methods or I have to use 3rd party frameworks for this functionality?

Hello, I'm writing to report an issue (or a documentation error). I am using the Entity/Component Architecture incorporated in the GamePlayKit framework. Additionally, I want to take advantage of the user interface provided by the Scene Editor. This is essential for me if I want to involve more people in the project. The issue occurs when linking the user interface data with the GKScene of the aforementioned framework. The first issue arises when adding a component through the interface as shown in the image Then at that moment: if let scene = GKScene(fileNamed: "GameScene") { // Get the SKScene from the loaded GKScene if let sceneNode = scene.rootNode as! GameScene? { Scene.rootNode is nil, and the scene is not presented. However, I can work around this issue by initializing the scene separately: if let scene = GKScene(fileNamed: "GameScene") { // Get the SKScene loaded separately if let sceneNode = SKScene(fileNamed: "GameScene") as! GameScene? { But from here, two issues arise: The node contains a component, and the scene has been loaded separately When trying to access a specific entity through its SKSpriteNode: self.node?.entity // Is nil It becomes very difficult to access a specific entity. When adding a component, an entity is automatically created. This is demonstrated here: The node contains a component, and the scene has been loaded separately. I only have one way to access this entity, and since there is only one, it's easy: sceneNode.entities[0] But even so, it's not very useful because when I try to access its components, it turns out they don't exist. I just wanted to mention this because it would be very helpful for me if this issue could be resolved. Thank you very much in advance.

I have tested my application in iOS 15, 16, 17 Version in that vision kit reading value in Horizontal direction once I got updated my device to iOS 18.0 beta value was reading as in vertical direction The build was generated in Xcode 13.4.1. Team please help to understand why this and need to change anything in code level

The following generates a prior definition warning from #include <__config>. But that has an ifndef in it. I'm in C++17 on Xcode latest (14.5). Is this documented anywhere? -D_LIBCPP_ENABLE_ASSERTIONS=1

I have a legacy app that draws using OpenGL, in particular is draws lines using glLineStipple. This is on a Macbook Pro M3, but it also happens on and x86 based Mac. This causes the following messages to be output to the terminal the app was run from: FALLBACK (log once): Fallback to SW vertex for line stipple FALLBACK (log once): Fallback to SW vertex processing, m_disable_code: 2000 FALLBACK (log once): Fallback to SW vertex processing in drawCore, m_disable_code: 2000 Is there a way of suppressing these messages?

I have a game for iOS where I use CADisplayLink to animate a simulation, and for some reason the animation is not getting the full 120hz on capable devices (like iPhone 15 Pro). When I enable a 120hz refresh target, the animation is capped at only 90hz. This looks terrible because the animation works best when doubled (30, 60, 120, 240, etc). The really bizarre thing is that when I turn on Screen Recording, my frame rate instantly jumps to 120, and everything looks perfectly smooth. My game has never looked better on iPhone! When recording is stopped, the animation drops back down to 90 fps. What in the world is going on? [displayLink setPreferredFrameRateRange:CAFrameRateRangeMake(100,240,120)]; //Min. Max, Preferred [displayLink addToRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode]; (Also, CADisableMinimumFrameDurationOnPhone is set to True in info.plist)

Hi, I was wondering if we could ever get the Game Porting Toolkit to ever translate Vulkan and Vulkan RT extensions? The reason I ask is because I would like to try something involving RTX Remix which requires Vulkan specific extensions

I have been using the iOS 18 public beta on my iPhone XR for the past 3-4 days, and I frequently play a popular competitive game called “Free Fire.” I’ve noticed an issue while playing the game. Whenever I switch the game to the background for any reason, such as using another app or attending an incoming call, the game’s sound does not come back when I switch back to it. No matter what I do—whether switching the phone to silent mode and then back to normal or adjusting the volume—the sound won’t return. I have to restart the game, which is frustrating since I play this game a lot. I understand that this is a beta version, and some problems are expected, but I wanted to mention this issue here in case it can be resolved. and i also tried some stuff like reinstalling the game or restrting the device or checking for new updates and all the small stuff that would fix this but nahhhh none of them worked 😅

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.

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.
