I am making a SpriteKit game and I am trying to change the cursor image from the default pointer to a png image that I have imported into the project, but it’s not really working. when I run the project I can see the cursor image change for a brief second and then return to the default image. Here is my code: print(NSCursor.current) if let image = NSImage(named: customImage) {      print("The image exists")      cursor = NSCursor(image: image, hotSpot: .zero)      cursor.push()      print(cursor) } print(NSCursor.current) The above code is all contained in the didMove(:) function in GameScene. From the print statements I can see that the memory address of the NSCursor.current changes to that of cursor. HOWEVER, in the mouseMoved(:) call back function I print out the mouse location and the current cursor. I can see from these print stamens that the cursor memory address has again changed and no longer matches the custom cursor address… so I am not sure what is going on… Also, fyi the cursor is a global property within game scene so it should persist. Also, image is not nil. This is verified by the print statements I see Thanks

I am trying to create an empty metadata, and set the HDRGainMapHeadroom at xxx. However the final returned mutableMetadata doesn't contain the HDRGainMap:HDRGainMapVersion or HDRGainMap:HDRGainMapHeadroom. But iio:hasXMP exist. why? Is that the reason that the namespace HDRGainMap is private? func createHDRGainMapMetadata(version: Int, headroom: Double) -> CGImageMetadata? { // Create a mutable metadata object let mutableMetadata = CGImageMetadataCreateMutable() // Define the namespace for HDRGainMap let namespace = "HDRGainMap" let xmpKeyPath = "iio:hasXMP" let xmpValue = String(true) // Set the HDRGainMapVersion item let versionKeyPath = "\(namespace):HDRGainMapVersion" let versionValue = String(version) // Set the version value let xmpSetResult = CGImageMetadataSetValueWithPath(mutableMetadata, nil, xmpKeyPath as CFString, xmpValue as CFString) if xmpSetResult == false { print("Failed to set xmp") } // Set the version value let versionSetResult = CGImageMetadataSetValueWithPath(mutableMetadata, nil, versionKeyPath as CFString, versionValue as CFString) if versionSetResult == false { print("Failed to set HDRGainMapVersion") } // Set the HDRGainMapHeadroom item let headroomKeyPath = "\(namespace):HDRGainMapHeadroom" let headroomValue = String(headroom) // Set the headroom value let headroomSetResult = CGImageMetadataSetValueWithPath(mutableMetadata, nil, headroomKeyPath as CFString, headroomValue as CFString) if headroomSetResult == false { print("Failed to set HDRGainMapHeadroom") } return mutableMetadata }

Hi, I have a full screen iOS game. In the Simulator, preferredScreenEdgesDeferringSystemGestures works well to prevent a drag down from the top of the full-screen play area from immediately opening the Notification Center. (You got a tab, and had to swipe down on it.) But at least on my device, when testing, unlike in Simulator, Notification Center opens immediately when I swipe down from the top. Any suggestions?

Hello, I've been tinkering with PortalComponent on visionOS a bit but noticed that the content of the WorldComponent is always clipped to the mesh geometry of whatever entities have the PortalComponent applied. Now I'm wondering if there is any way or trick to allow contents of the portal to peek out – similar to the Encounter Dinosaurs experience on Vision Pro (I assume it also uses PortalComponent?). I saw that PortalComponent has a clippingPlane property (https://developer.apple.com/documentation/realitykit/portalcomponent/clippingplane-swift.property). But so far I haven't been able to achieve a perceptible visual difference with it. If possible I would like to avoid hacky tricks using duplicate meshes or similar to achieve this. Thanks for any hints!

Dobrý den, koupil jsem si IPhone 13 a na displeji přesně uprostřed tlačítka hlasitosti (+) je tečka. Vypadá to jako kdyby to byla nějaká funkce či co, ale na nic jsem nepřišel. Nevím jestli je to vada nebo ne.

I plan to create a simple motion graphics software for macOS that animates text, basic shapes, and handles audio. I'll use SwiftUI for the UI. What are the commonly used technologies for rendering animated graphics? Core Animation is suitable for UI animations but not for exporting and controlling UI animations. Basic requirements: Timeline user interface Animation of text and basic shapes Viewer in SwiftUI GUI with transport control (play, pause, scrub, …) Export to video file Is Metal or Core Graphics typically used directly? I want to keep it as simple as possible.

__builtin_ia32_cvtb2mask512() is the GNU C builtin for vpmovb2m k, zmm. The Intel intrinsic for it is _mm512_movepi8_mask. It extracts the most-significant bit from each byte, producing an integer mask. The SSE2 and AVX2 instructions pmovmskb and vpmovmskb do the same thing for 16 or 32-byte vectors, producing the mask in a GPR instead of an AVX-512 mask register. (_mm_movemask_epi8 and _mm256_movemask_epi8). I would like an implementation for ARM that is faster than below I would like an implementation for ARM NEON I would like an implementation for ARM SVE I have attached a basic scalar implementation in C. For those trying to implement this in ARM, we care about the high bit, but each byte's high bit (in a 128bit vector), can be easily shifted to the low bit using the ARM NEON intrinsic: vshrq_n_u8(). Note that I would prefer not to store the bitmap to memory, it should just be the return value of the function similar to the following function. #define _(n) __attribute((vector_size(1<<n),aligned(1))) typedef char V _(6); // 64 bytes, 512 bits typedef unsigned long U; #undef _ U generic_cvtb2mask512(V v) { U mask=0;int i=0; while(i<64){ // shift mask by 1 and OR with MSB of v[i] byte mask=(mask<<1)|((v[i]&0x80)>>7); i++;} return mask; } This is also a dup of : https://stackoverflow.com/questions/79225312

I’m trying to build my project using Unreal Engine 5.4 for iOS. I use SocketIO to connect to the backend. The plugin SocketIOClient version 2.8.0, is used for this. When trying to connect to the socket, a crash occurs. This only happens on iOS, only in Distribution builds, and only on Unreal 5.4. There are no problems on Unreal 5.2. Callstack: crashlog.crash The callstack may be slightly different, but the problem is always when allocating or deallocating memory. I suspect that this may be a race condition and is related to some peculiarities of working with memory on iOS. There are also several similar issues in the plugin repository, for example this one. I tried using other versions of plugin, other versions of xcode, tried to build socket io using both c++20 and c++17, nothing helps. Does anyone know what can be done about this?

Dear Apple Support Team, I recently purchased an iPad Pro 2022 and updated it to iOS 18.2. However, I am experiencing an issue while using Call of Duty Mobile. The Game Mode activates randomly and sometimes does not activate at all. Additionally, when the Game Mode is on, the game crashes unexpectedly, causing an unstable experience. I kindly request that you address this issue in upcoming iOS updates. Thank you for your attention and support. Best regards, [samadBg]

I want to implement the ability to apply Lightroom Preset (.xmp file) to an image in my app, but am running into difficulties. How can I configure things like color grading, curve, etc. in Swift?

I am trying to install the game-porting-toolkit using brew -v install apple/apple/game-porting-toolkit but this fails each time because of a dependency on a deprecated openssl version: Fetching dependencies for apple/apple/game-porting-toolkit: cmake, ninja, apple/apple/game-porting-toolkit-compiler, openssl1.1 ... ... Error: openssl@1.1 has been disabled because it is not supported upstream! It was disabled on 2024-10-24. Is there a way to override this dependency or use a newer version of openssl for the check?

Hi guys! Is there any way to get a frame at certain time? I'm writing plug-in and want to use 2 frames before and 2 frames after current frame in order to render final image.

Sample project from: https://developer.apple.com/documentation/RealityKit/guided-capture-sample was fine with beta 3. In beta 4, getting these errors: Generic struct 'ObservedObject' requires that 'ObjectCaptureSession' conform to 'ObservableObject' Does anyone have a fix? Thanks

I tried using the GameController APIs for this, but they didn't seem to work. Is that the recommended API for handling keyboard/mouse? The notifications for mouse and keyboard connect/disconnect don't seem to be defined for visionOS. The visionOS 2.0 touts keyboard and mouse support. The simulator can even forward keyboard/mouse to the app. But there don't seem to be any sample code of how to programatically receive either of these. The game controller works fine (on device, not on Simulator).

I have this game controller connected to my M1, and the Simulator won't announced it via .GCControllerDidConnect. This works fine on iOS and macOS. I have the simulator set to "Send Game Controller to Device" which the Simulator does. If I disable that, then I can control the simulator view. But once enabled, the Simulator doesn't tell the app about the controller.

I want to know why there is no video frame data when RePlaykit enters the background and then enters the foreground?

For some reason I can't disable the Graphics HUD. Not really a problem for development, but it's also showing in Testflight apps. For example when swiping down on the keyboard but also in some other places. Of course I tried disabling the toggle, but even when it's off the HUD is still showing. Even completely disabling Developer mode does not work. Is this a known issue? I already scrolled through possibly every Google search result but I can't figure out how to solve this.

Guys, In my main application bundle, I have included a helper bundle in its Resources. When the helper requests Accessibility permission, the system modal window displays what the helper is requesting permission for. However, when the helper requests permission for Screen Recording, the system modal window displays that the main application bundle is requesting permission, which includes the helper. This issue seems to be specific to Ventura, as both requests are displayed on behalf of the helper in Monterey. I'm wondering if this is a known issue or limitation or if there is a way to make the permission request specifically from the helper.
