I would like to know if the applications/games targeting the Metal 3 API will be fully compatible with the M1 Pro GPU. Thanks.

I'm testing all of the existing mapping SDKs from Unity via the PolySpatial workflow to see if any of them work on the Vision Pro. ArcGIS and Bing SDKs both play successfully in Editor, and Build successfully from Unity, but they both hit the same errors when building in Xcode (captured in screenshot attached). Is this a common error in Xcode? I can't find much on it. Thanks!

Hello everyone, I want to develop an app for vision pro that aims to help people with vertigo and dizziness problems. The problem is that I can not afford vision pro. If I use standart vr set with an iPhone inside would it cause issues on real vision pro?

CGImageSourceCreateThumbnailAtIndex function isn't generating cgImage for majority of the images on iOS 17.4 OS version. It works if I pass in option kCGImageSourceThumbnailMaxPixelSize, but doesn't work if this key is missing. This function works with and without kCGImageSourceThumbnailMaxPixelSize in stable OS versions. Is this a new change in iOS 17.4 beta versions?

Can someone explain the difference between MTLHazardTrackingModeTracked and MTLResourceHazardTrackingModeTracked please?

I init openGL now i wanna set glPixelZoom(pixelSizeX, -pixelSizeY); to dispaly a image with width and height to the entire window for this I do: rect:= window.frame; WindowBackingRect := window.convertRectToBacking(rect); pixelSizeX := WindowBackingRect.size.width / width / NSScreen.mainScreen.backingScaleFactor; pixelSizeY := WindowBackingRect.size.height / height / NSScreen.mainScreen.backingScaleFactor; under High Sierra 10.13.6 on an intel mac from 2011 NSScreen.mainScreen.backingScaleFactor return 1 because there is no retina. under Sonoma 14.3 an an intel mac from 2020 NSScreen.mainScreen.backingScaleFactor return 2 because of retina. this works correct. under Venture 13.6 on an aarch64 mac from 2020 NSScreen.mainScreen.backingScaleFactor returns 2 BUT the image is only half so big as it should be. (if i let the scale factor away on the new intel mac, the image is twice big as it should be. On the new AArch64 mac it is correct.) what to do?

Hi, I am using metallib to generate shader cache shaders offline, but I have noticed that for certain .air files, metallib's behavior is unpredictable.

Please clarify if latest guides update allow to html5 games without binary inclusion. Does that mean that gambling apps do not required embedded resources for real money games in the app?

Seems that metal-shaderconverter can build a metallib, but I need .air files. Then I link the .air files into a single metallib and metallibdsym file. HLSL -> dxc -> DXIL -> metal-shaderconverter -> .metallib But there's no way to link together multiple metallib into a single metallib is there?

Hi, I'm building a simple game for iOS. I have background music. The ring/silent switch is not disabling sound when switched to silent. So far I'm testing on devices through TestFlight (still internal testing, not beta). Do I need to code this function myself or does iOS know it's a game and disable sound automatically? and/or would my game be rejected if the switch doesn't disable sound? (I have an internal setting to enable/disable sounds in the game) Due to the way it's coded (capacitor app), I can't access the ring/silent switch to disable/enable sound. Thanks, this problem makes me feel like a preserved moose.

Hello community this post is for show my complete unsatisfied with Apple specially on developing games for Apples platforms there is lack of support for it for example some new gaming technologies and still that there is no profit or worth from all the work and money invested to develop for it I will close the journey with Apple very unsatisfied I'm going to give opportunities with my business to other platforms that are really worth it and give support to all new technologies in gaming and yes Apple destroyed other gaming makers with their new services like arcade and seems no future for gaming in Apples platforms. Quit goodbye and good luck to everyone.

First of all, I apologize for such a general question, but my code is far too long to post. However, I have narrowed down my problems and am seeking advice for any solutions/workarounds that may help me. I recently updated my physics simulation code from using Metal Performance Shaders for ray tracing to using the (fairly) new Metal ray tracing routines directly. A few notes on my program: I perform the ray tracing entirely in a separate thread using Compute Kernels -- there is no rendering based on the ray tracing results. The compute kernels are called repeatedly and each ends with a waitUntilCompleted() command. The main thread is running a SwiftUI interface with some renderings that use RealityKit to display the scene (i.e., the vertices), and the rays that traverse the scene using Metal Ray Tracing. This is purely a Mac program and has no IOS support. So, the problem is that there seems to be some conflict between RealityKit rendering and the ray-tracing compute kernels where I will get a "GPU Soft Fault" when I run the "intersect" command in Metal. After this soft-fault error, my Ray Tracing results are completely bogus. I have figured out a solution to this which is to refit my acceleration structures semi-regularly. However, this solution is inelegant and probably not sustainable. This problem gets worse the more I render in my RealityKit display UI (rendered as a SwiftUI view) so I am now confident that the problem is some "collision" between the GPU resources needed by my program and RealityKit. I have not been able to find any information on what a "GPU Soft Fault" actually is although I suspect it is a memory violation. I suspect that I need to use fences to cordon off my ray tracing compute kernel from other things that use Metal (i.e., RealityKit), however I am just not sure if this is the case or how to accomplish this. Again, I apologize for the vague question, but I am really stuck. I have confirmed that every Metal buffer I pass to my compute kernel is correct. I did this confirmation by making my object a simple cube and having only one instance of this cube. Something happens to either corrupt the acceleration structure data or to make it inaccessible during certain times when RealityKit needs to use the GPU. Any advice would be appreciated. I have not submitted a bug report since I am still not sure if this is just my lack of advanced knowledge of multiple actors requiring GPU use or if there is something more serious here. Thanks in advance, -Matt

Hi, I have a MBP 2023 M3 Max 64GB with 16 Core CPU ( 4 efficiency, 12 Performance) and 40C GPU. I've got a Game (Cities Skylines 2) successfully working using Whisky. However, only 4 Cores are reported to the game which leads to a situation where there are many calculations batched up while at the same time my CPU performance cores almost idle, while the efficiency cores are well utilized. I suspect this is because the game only sees 4 cores and has some logic to batch the calculations differently depending on how much cores are available. Is there a way to override how many cores the game sees? e.g. by using an environment variable or something? Thanks, Dominik

I captured my office using 3D Scanner and get a USDZ file. The file contains a 3-D Model and a Physically based material. I can view the file correctly with texture on Xcode and Reality Composer Pro. But when using RealityView to present the model in immersive space. I got the model in whole black. My guess is my Material doesn't have a shader graph? Does anyone caught into similar issue? How to solve it?

I’m really sorry if this is not the proper place for this. I’m developing a game with online mode what works just fine in WiFi mode but not in mobile network. If someone has two Apple devices and can try if with the mobile network the multiplayer mode works I will appreciate A LOT https://apps.apple.com/es/app/ufo-snowboard/id6474542185

I have build the plugins and added to project but when I run game I am getting these errors https://github.com/apple/unityplugins EntryPointNotFoundException: AppleCore_GetRuntimeEnvironment assembly: type: member:(null) Apple.Core.Availability.OnApplicationStart () (at Library/PackageCache/com.apple.unityplugin.core@d07a9d20344c/Runtime/Availability.cs:40) EntryPointNotFoundException: GKLocalPlayer_GetLocal assembly: type: member:(null)

As I understood, the ability to use metal is only in "vr" mode. But is there any way to make a custom post-process in mixed reality mode?

Hi, i am required to upload my CFD simulation results to the new vision pro glasses. This simulation shall be visible as a soft VR/AR object in the room. I am very new to the developer world. Could someone give me a hint which IDE, tool etc. to use for this task? SwiftUI, swift, visionOS, Xcode, ... ???? After I know what IDE/tool/language to use, I will start learning courses with it. Thanks a lot!!
