Is it possible to start screen recording (through Control Center) without user prompt?
I mean to ask user permission for the first time and after that to start and stop recording programmatically only?
I need to record screen only for specific events.

I have a model that uses a video material as the surface shader and I need to also use a geometry modifier on the material.
This seemed like it would be promising (adapted from https://developer.apple.com/wwdc21/10075 ~5m 50s).
// Did the setup for the video and AVPlayer eventually leading me to
let videoMaterial = VideoMaterial(avPlayer: avPlayer)
// Assign the material to the entity
entity.model!.materials = [videoMaterial]
// The part shown in WWDC: Set up the library and geometry modifier before, so now try to map the new custom material to the video material
entity.model!.materials = entity.model!.materials.map { baseMaterial in
try! CustomMaterial(from: baseMaterial, geometryModifier: geometryModifier)
}
But, I get the following error
Thread 1: Fatal error: 'try!' expression unexpectedly raised an error: RealityFoundation.CustomMaterialError.defaultSurfaceShaderForMaterialNotFound
How can I apply a geometry modifier to a VideoMaterial? Or, if I can't do that, is there an easy way to route the AVPlayer video data into the baseColor of CustomMaterial?
I am currently developing a mobile and server-side application using the new ObjectCaptureSession on iOS and PhotogrammetrySession on MacOS.
I have two questions regarding the newly updated APIs.
From WWDC23 session: "Meet Object Capture for iOS", I know that the Object Capture API uses Point Cloud data captured from iPhone LiDAR sensor. I want to know how to use the Point Cloud data captured on iPhone ObjectCaptureSession and use it to create 3D models on PhotogrammetrySession on MacOS.
From the example code from WWDC21, I know that the PhotogrammetrySession utilizes depth map from captured photo images by embedding it into the HEIC image and use those data to create a 3D asset on PhotogrammetrySession on MacOS. I would like to know if Point Cloud data is also embedded into the image to be used during 3D reconstruction and if not, how else the Point Cloud data is inserted to be used during reconstruction.
Another question is, I know that Point Cloud data is returned as a result from request to the PhtogrammetrySession.Request. I would like to know if this PointCloud data is the same set of data captured during ObjectCaptureSession from WWDC23 that is used to create ObjectCapturePointCloudView.
Thank you to everyone for the help in advance. It's a real pleasure to be developing with all the updates to RealityKit and the Object Capture API.
Does anyone know if we will be able to airplay content from another Apple device, say an iPad or iPhone to the Vision Pro?
I'm an iOS developer, and I've been testing our app in iOS 18.0 Beta. I noticed that there's a problem with the font rendering, and after troubleshooting, I've found out that it's caused by the removal of the PingFang.ttc font in 18.0.
I would like to ask the reason for removing this font file and which font should be used to display Chinese in the future?
My test device is an iPhone 11 Pro and the system version is iOS 18.0 (22A5297). I have also tested Beta 1 and it has the same issue.
In previous versions of the system, the PingFang font is located in this directory /System/Library/Fonts/LanguageSupport/PingFang.ttc. But in iOS 18.0, the font file in this directory has become Kohinoor.ttc, and I've tested that this font can't display Chinese either.
I traversed the following system font directories and could not find the PingFang.ttc font file.
/System/Library/Fonts/AppFonts
/System/Library/Fonts/Core
/System/Library/Fonts/CoreAddition
/System/Library/Fonts/CoreUI
/System/Library/Fonts/LanguageSupport
/System/Library/Fonts/UnicodeSupport
/System/Library/Fonts/Watch
Looking for answers, thanks for the help!
So I get JPEG data in my app. Previously I was using the higher level NSBitmapImageRep API and just feeding the JPEG data to it.
But now I've noticed on Sonoma If I get a JPEG in the CMYK color space the NSBitmapImageRep renders mostly black and is corrupted. So I'm trying to drop down to the lower level APIs. Specifically I grab a CGImageRef and and trying to use the Accelerate API to convert it to another format (to hopefully workaround the issue...
CGImageRef sourceCGImage = `CGImageCreateWithJPEGDataProvider(jpegDataProvider,`
NULL,
shouldInterpolate,
kCGRenderingIntentDefault);
Now I use vImageConverter_CreateWithCGImageFormat... with the following values for source and destination formats:
Source format: (derived from sourceCGImage)
bitsPerComponent = 8
bitsPerPixel = 32
colorSpace = (kCGColorSpaceICCBased; kCGColorSpaceModelCMYK; Generic CMYK Profile)
bitmapInfo = kCGBitmapByteOrderDefault
version = 0
decode = 0x000060000147f780
renderingIntent = kCGRenderingIntentDefault
Destination format:
bitsPerComponent = 8
bitsPerPixel = 24
colorSpace = (DeviceRBG)
bitmapInfo = 8197
version = 0
decode = 0x0000000000000000
renderingIntent = kCGRenderingIntentDefault
But vImageConverter_CreateWithCGImageFormat fails with kvImageInvalidImageFormat. Now if I change the destination format to use 32 bitsPerpixel and use alpha in the bitmap info the vImageConverter_CreateWithCGImageFormat does not return an error but I get a black image just like NSBitmapImageRep
Hi,
wanted to test if possible to use Mesa3D OGLon12+D3DMetal 2b3 to get GL>4.1 support on windows apps via D3D12Metal..

Question:
I'm encountering an issue with in-app purchases (IAP) in Unity, specifically for a non-consumable product in the iOS sandbox environment. Below are the details:
Environment:
Unity Version: 2022.3.55f1 Unity In-App Purchasing
Version: v4.12.2
Device: iPhone (15, iOS 18.1.1)
Connection: Wi-Fi iOS
Settings: In-App Purchases set to “Allowed” initially Problem Behavior:
I attempted to purchase a non-consumable item for the first time. The payment is successfully completed by entering the password.
I then background the game app and navigate to the iOS Settings to set In-App Purchases to "Don't Allow."
After returning to the game and either closing or killing the app, I try to purchase the same non-consumable item again.
I checked canMakePayments() through the Apple configuration, and the app correctly detected that I could not make purchases due to the restriction.
I then navigate back to Settings and set In-App Purchases to "Allow."
Upon returning to the game, I try purchasing the non-consumable item again. A pop-up appears, saying, "You’ve already purchased this. Would you like to get it again for free?"
The issue is: Will it deduct money for the second time, and why is the system allowing the user to purchase the same non-consumable item multiple times after purchasing it once?
Is this the expected behavior for Unity In-App Purchasing, or is there something I might be missing in handling non-consumable purchases in this scenario?
Additional Information:
I’ve confirmed that the "In-App Purchases" are set to “Allowed” before attempting the purchase again.
I understand that non-consumable products should not be purchased more than once, so I’m unsure why the system is offering to let the user purchase it again.
I appreciate any insights into whether this is expected behavior or if I need to adjust how I handle the purchase flow.
Create the QRCode
CIFilter<CIBlendWithMask> *f = CIFilter.QRCodeGenerator;
f.message = [@"Message" dataUsingEncoding:NSASCIIStringEncoding];
f.correctionLevel = @"Q"; // increase level
CIImage *qrcode = f.outputImage;
Overlay the icon
CIImage *icon = [CIImage imageWithURL:url];
CGAffineTransform *t = CGAffineTransformMakeTranslation(
(qrcode.extent.width-icon.extent.width)/2.0,
(qrcode.extent.height-icon.extent.height)/2.0);
icon = [icon imageByApplyingTransform:t];
qrcode = [icon imageByCompositingOver:qrcode];
Round off the corners
static dispatch_once_t onceToken;
static CIWarpKernel *k;
dispatch_once(&onceToken, ^ {
k = [CIWarpKernel kernelWithFunctionName:name

error:nil];
});
CGRect iExtent = image.extent;
qrcode = [k applyWithExtent:qrcode.extent
roiCallback:^CGRect(int i, CGRect r) {
return CGRectInset(r, -radius, -radius); }
inputImage:qrcode
arguments:@[[CIVector vectorWithCGRect:qrcode.extent], @(radius)]];
…and this code for the kernel should go in a separate .ci.metal source file:
float2 bend_corners (float4 extent, float s, destination dest)
{
float2 p, dc = dest.coord();
float ratio = 1.0;
// Round lower left corner
p = float2(extent.x+s,extent.y+s);
if (dc.x < p.x && dc.y < p.y) {
float2 d = abs(dc - p);
ratio = min(d.x,d.y)/max(d.x,d.y);
ratio = sqrt(1.0 + ratio*ratio);
return (dc - p)*ratio + p;
}
// Round lower right corner
p = float2(extent.x+extent.z-s, extent.y+s);
if (dc.x > p.x && dc.y < p.y) {
float2 d = abs(dc - p);
ratio = min(d.x,d.y)/max(d.x,d.y);
ratio = sqrt(1.0 + ratio*ratio);
return (dc - p)*ratio + p;
}
// Round upper left corner
p = float2(extent.x+s,extent.y+extent.w-s);
if (dc.x < p.x && dc.y > p.y) {
float2 d = abs(dc - p);
ratio = min(d.x,d.y)/max(d.x,d.y);
ratio = sqrt(1.0 + ratio*ratio);
return (dc - p)*ratio + p;
}
// Round upper right corner
p = float2(extent.x+extent.z-s, extent.y+extent.w-s);
if (dc.x > p.x && dc.y > p.y) {
float2 d = abs(dc - p);
ratio = min(d.x,d.y)/max(d.x,d.y);
ratio = sqrt(1.0 + ratio*ratio);
return (dc - p)*ratio + p;
}
return dc;
}
I have a UIView that displays lines, and I zoom in (scale by 2 on the scroll view zoomScale variable containing the UIView).
As I zoom in, on the Mac version (Designed for IPad) I loose the graphic after a certain number of zooms (the scrollView maximumZoomScale is set at 10).
To ensure that lines are correctly represented, I modify the contentScaleFactor variable on the UIView; otherwise, the line's display is pixelated.
On the IPad (simulator and real) I do not loose the graphic when zooming.
So the Mac port of the UIView drawing is not working as the IPad version.
Everything else of the application works fine except this important details.
I already submitted a feedback request (#FB16829106) with the images showing the problem. I need a solution to this problem.
Thanks.
Hi, I am trying to detect if all the screen are in fullscreen mode.
The current approach is to get all windows' information from CGWindowListCopyWindowInfo and then compare the frame and coordinate with the frame of NSScreen.screens.
However, there is a problem, the y position of the window seems to be relative to the screen. As it is not absolute position, I cannot compare it with the coordinate of the screen.
Does anyone know if there are other information that I can use? Or is there a way to retrieve the absolute position or screen ID from the GCWIndow object?
i have a game that i upload it in the app store that my game size is 3 gigaByte but when I download it, it show that the really size is about 100 megaByte, i upload the game in google app is given me the real size,
so the problem i think is when it get out the xcode, maybe some one can give me i clue for what is going on.
my game was made by unity2020.
if that helps.
I am trying to install the Game Porting Toolkit 2.1 according to the Readme file provided with the toolkit.
When I run the following command:
WINEPREFIX=~/my-game-prefix brew --prefix game-porting-toolkit/bin/wine64 winecfg
I get an error message:
zsh: no such file or directory: /usr/local/opt/game-porting-toolkit/bin/wine64
I don't know how to resolve this.
When I type in the command which brew , I get the path
/usr/local/bin/brew
What am I doing wrong?
Hi everyone,
I'm using the Vision framework’s ImageAestheticsScoresObservation class (https://developer.apple.com/documentation/vision/imageaestheticsscoresobservation).
I noticed that the overallScore returned sometimes gives negative values. Could someone confirm whether the expected range of the score is from -1.0 to 1.0?
The documentation doesn’t explicitly state the possible score range, so I’d appreciate any clarification or insights.
Thanks in advance!
Dear Apple, there is still no support for WebGPU via WebView. Do you have a roadmap on when you plan to support it? That would be very helpful to release our new game.

My app is being rejected and all I'm being told is that it is spam.
I've tried improving various aspects of the game, but I just receive the same copy and paste rejection message each time.
I have no idea if I'm moving in the right direction or what part of my game needs to be changed or improved. Is there a game quality benchmark document or some kind of resource I can use to better understand why my game is being rejected and how to bring it to a level that meets apple's standards.
What is Game Mode?
Game Mode optimizes your gaming experience by giving your game the highest priority access to your CPU and GPU, lowering usage for background tasks. And it doubles the Bluetooth sampling rate, which reduces input latency and audio latency for wireless accessories like game controllers and AirPods.
See Use Game Mode on Mac
See Port advanced games to Apple platforms
How can I enable Game Mode in my game?
Add the Supports Game Mode property (GCSupportsGameMode) to your game’s Info.plist and set to true
Correctly identify your game’s Application Category with LSApplicationCategoryType (also Info.plist)
Note:
Enabling Game Mode makes your game eligible but is not a guarantee; the OS decides if it is ok to enable Game Mode at runtime
An app that enables Game Mode but isn’t a game will be rejected by App Review.
How can I disable Game Mode?
Set GCSupportsGameMode to false.
Note: On Mac Game Mode is automatically disabled if the game isn’t running full screen.
I am suspecting that setting GCController.shouldMonitorBackgroundEvents = true does not actually make the game controllers inputs accessible to the app when it is in the background.
About this value the official documentation says:
A Boolean value that indicates whether the app needs to respond to controller events when it isn’t the frontmost app.
Now the behavior is that when the app is in focus the users inputs do get correctly recognized but as soon as the app enters the background no inputs get recognized. The controller does not get reported as disconnecting and still works for example in launchpad.
I am sure that about 2 months ago when I first used this it did work as one would expect. I also have seen that an app which lets users execute certain actions using their controller has stoped working recently, adding to my suspicion of the feature being broken.
Here is a minimum reproducible example:
import SwiftUI
import GameController
@main
struct TestingControllerConnectionApp: App {
@NSApplicationDelegateAdaptor(AppDelegate.self) var appDelegate
var body: some Scene {
WindowGroup {
ContentView()
}
}
}
class AppDelegate: NSObject, NSApplicationDelegate {
var statusItem: NSStatusItem?
var controller: GCController?
func applicationDidFinishLaunching(_ notification: Notification) {
setupMenuBar()
GCController.shouldMonitorBackgroundEvents = true
NotificationCenter.default.addObserver(
self,
selector: #selector(controllerDidConnect),
name: .GCControllerDidConnect,
object: nil
)
NotificationCenter.default.addObserver(
self,
selector: #selector(controllerDidDisconnect),
name: .GCControllerDidDisconnect,
object: nil
)
}
@objc private func setupMenuBar() {
let menu = NSMenu()
menu.addItem(NSMenuItem(title: "Quit", action: #selector(quitApp), keyEquivalent: "q"))
statusItem = NSStatusBar.system.statusItem(withLength: NSStatusItem.variableLength)
statusItem?.button?.image = NSImage(resource: .controllerBar)
statusItem?.menu = menu
}
@objc private func quitApp() {
NSApp.terminate(nil)
}
@objc private func controllerDidConnect(_ notification: Notification) {
if let controller = notification.object as? GCController {
print("Controller connected")
self.controller = controller
if let gamepad = controller.extendedGamepad {
gamepad.buttonA.pressedChangedHandler = { _, _, pressed in
print("Button A pressed: \(pressed)")
}
}
}
}
@objc private func controllerDidDisconnect(_ notification: Notification) {
print("Controller disconnected")
}
}
This is created in a completely fresh Xcode project and NSHumanInterfaceDeviceUsageDescription has been added.
I am using a PS5 Controller and a Mac running MacOS 15.4.1 which has been restarted and only Xcode and the app have been opened.
I have tested this with setting a multitude of different entitlements and capabilities including:
NSHumanInterfaceDeviceUsageDescription
Supports Controller User Interaction
Required background modes -> App communicates with an accessory
com.apple.security.device.bluetooth
com.apple.security.device.hid
com.apple.security.device.usb
I have also set this value at different points in the code with no change of effect.
Does anybody see if there is any fault in my code or my understanding of the effect of the value 'shouldMonitorBackgroundEvents'? Or is this the functionality actually being broken on Apples part?
Due to the release of ProMotion devices, the system may switch frame rates in certain scenarios, resulting in the loss of reference value for data collected through CADisplayLink callbacks at a fixed 60Hz frame rate. We cannot distinguish whether the slow callback of CADisplayLink is due to a stutter or a system switch in frame rate.
I know Hitch Time Ratio, but I can't use this scheme for some reasons.
How can I distinguish between stuck and frame rate gear shift in CADisplaylink callback?
In iOS 15, CADisplayLink.preferredFrameRateRange.preferred always returns 0, while minimum and maximum do change. Can I use these minimum and maximum range values as criteria to distinguish between frame rate switching and stuttering?
