Hi everyone,
I faced an issue that on IOS 26 removeAnnotation method doesn't remove annotation. This code worked on previous versions (IOS 18, 17) but suddenly stopped working on IOS 26.
Has anyone faced this issue?
guard let document = await pdfView.document else { return }
for pageIndex in 0..<document.pageCount {
guard let page = document.page(at: pageIndex) else { continue }
let annotations = page.annotations
for annotation in annotations {
page.removeAnnotation(annotation)
}
}

Hello, I am trying to capture screen recording ( output.mp4 ) using ScreenCaptureKit and also the mouse positions during the recording ( mouse.json ). The recording and the mouse positions ( tracked based on mouse movements events only ) needs to be perfectly synced in order to add effects in post editing.
I started off by using the await stream?.startCapture() and after that starting my mouse tracking function :-
try await captureEngine.startCapture(configuration: config, filter: filter, recordingOutput: recordingOutput)
let captureStartTime = Date()
mouseTracker?.startTracking(with: captureStartTime)
But every time I tested, there is a clear inconsistency in sync between the recorded video and the recorded mouse positions.
The only thing I want is to know when exactly does the recording "actually" started so that I can start the mouse capture at that same time, and thus I tried using the Delegates, but being able to set them up perfectly.
import Foundation
import AVFAudio
import ScreenCaptureKit
import OSLog
import Combine
class CaptureEngine: NSObject, @unchecked Sendable {
private let logger = Logger()
private(set) var stream: SCStream?
private var streamOutput: CaptureEngineStreamOutput?
private var recordingOutput: SCRecordingOutput?
private let videoSampleBufferQueue = DispatchQueue(label: "com.francestudio.phia.VideoSampleBufferQueue")
private let audioSampleBufferQueue = DispatchQueue(label: "com.francestudio.phia.AudioSampleBufferQueue")
private let micSampleBufferQueue = DispatchQueue(label: "com.francestudio.phia.MicSampleBufferQueue")
func startCapture(configuration: SCStreamConfiguration, filter: SCContentFilter, recordingOutput: SCRecordingOutput) async throws {
// Create the stream output delegate.
let streamOutput = CaptureEngineStreamOutput()
self.streamOutput = streamOutput
do {
stream = SCStream(filter: filter, configuration: configuration, delegate: streamOutput)
try stream?.addStreamOutput(streamOutput, type: .screen, sampleHandlerQueue: videoSampleBufferQueue)
try stream?.addStreamOutput(streamOutput, type: .audio, sampleHandlerQueue: audioSampleBufferQueue)
try stream?.addStreamOutput(streamOutput, type: .microphone, sampleHandlerQueue: micSampleBufferQueue)
self.recordingOutput = recordingOutput
recordingOutput.delegate = self
try stream?.addRecordingOutput(recordingOutput)
try await stream?.startCapture()
} catch {
logger.error("Failed to start capture: \(error.localizedDescription)")
throw error
}
}
func stopCapture() async throws {
do {
try await stream?.stopCapture()
} catch {
logger.error("Failed to stop capture: \(error.localizedDescription)")
throw error
}
}
func update(configuration: SCStreamConfiguration, filter: SCContentFilter) async {
do {
try await stream?.updateConfiguration(configuration)
try await stream?.updateContentFilter(filter)
} catch {
logger.error("Failed to update the stream session: \(String(describing: error))")
}
}
func stopRecordingOutputForStream(_ recordingOutput: SCRecordingOutput) throws {
try self.stream?.removeRecordingOutput(recordingOutput)
}
}
// MARK: - SCRecordingOutputDelegate
extension CaptureEngine: SCRecordingOutputDelegate {
func recordingOutputDidStartRecording(_ recordingOutput: SCRecordingOutput) {
let startTime = Date()
logger.info("Recording output did start recording \(startTime)")
}
func recordingOutputDidFinishRecording(_ recordingOutput: SCRecordingOutput) {
logger.info("Recording output did finish recording")
}
func recordingOutput(_ recordingOutput: SCRecordingOutput, didFailWithError error: any Error) {
logger.error("Recording output failed with error: \(error.localizedDescription)")
}
}
private class CaptureEngineStreamOutput: NSObject, SCStreamOutput, SCStreamDelegate {
private let logger = Logger()
override init() {
super.init()
}
func stream(_ stream: SCStream, didOutputSampleBuffer sampleBuffer: CMSampleBuffer, of outputType: SCStreamOutputType) {
guard sampleBuffer.isValid else { return }
switch outputType {
case .screen:
break
case .audio:
break
case .microphone:
break
@unknown default:
logger.error("Encountered unknown stream output type:")
}
}
func stream(_ stream: SCStream, didStopWithError error: Error) {
logger.error("Stream stopped with error: \(error.localizedDescription)")
}
}
I am getting error
Value of type 'SCRecordingOutput' has no member 'delegate'
Even though I am targeting macOs 15+ ( macOs 26 actually ) and macOs only.
What is the best way to achieving the desired result? Is there any other / better way to do it?

Just found out this key available for visionOS
https://developer.apple.com/documentation/bundleresources/entitlements/com.apple.developer.low-latency-streaming
It seems to keep video streaming from being interrupted by AWDL, our community needs it badly for self-hosted game streaming (PC to iPhone / iPad).
Related apps: Moonlight / VoidLink / SteamLink.
Can we expect this on iOS/iPadOS 26, or even iOS/iPadOS 18 ?

I think I really have tried everything and I did all according to official documentation to support game mode on iOS or iPadOS but it doesn't matter what I do it just doesn't get triggered. Funny enough it works during development when I install it via Xcode but as soon as it is live on the store and when I install it from there game mode doesn't get triggered anymore. What I have atm
I have added (even though it is deprecated)
<key>GCSupportsGameMode</key>
<true/>
I have set the (but it seems only supported for macOS)
<key>LSApplicationCategoryType</key>
<string>public.app-category.games</string>
I have added
<key>LSSupportsGameMode</key>
<true/>
It just doesn't work. Is there anything else what needs to be done? Should the flag LSSupportsGameMode not be enough normally?
The reason why this is so annoying is that my app is a real time streaming app and I want to profit from minimised background activities for smoother gameplay and more consistent frame rates like mentioned in the documentation.
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 searched the Metal Shading Language Specification Version 3.0 document, however I cannot see any function for inverting a matrix. Is there really no function in Metal for inverting a matrix?
I often need to this in linear equations and have so far resorted to writing the necessary function each time, most of the time just copy-and-pasting code.
inverse exists in SIMD and GLSL, so why not in Metal? It seems so unexpected that this function does not exist that I am almost certain I have just overlooked something obvious. I even tried 1 / M, to no avail.
Hi,
The metal-cpp distribution appears to only contain headers for Foundation and Quartzcore. The LearnMetalCPP download [1] provides a ZIP with an metal-cpp-extensions directory containing AppKit.hpp and MetalKit.hpp headers. First question: Are these headers distributed anywhere else more publicly? Without these headers only the renderer can be fully written in C++ as far as I can tell, i.e. no complete C++ NSApplication. Second question: Will these headers, if needed, be maintained (e.g. updated and/or extended) by Apple along side metal-cpp?

Thank you and regards.

I have used the Mac M1 and M4.
Developing OpenGL projects on machines running macOS 15.2 and 13.6.
Call the OpenGL library functions of Mac.
glTexImage2D
If you use GL_LUMINANCE, GL_LUMINANCE_ALPHA, GL_ALPHA these three textures, you will get an error gl 500.
It makes me unable to draw normally on Mac.
What's the reason for this? Don't they support it?
Hey there,
I tried to install GPTK again, since I had to reinstall the OS for irrelevant reasons. But every time I try to install the tool kit, it gives me theError: apple/apple/game-porting-toolkit 1.1 did not build error. Before that error occired, I had the Openssl error, which I fixed with the rbenv version of openssl. Is there any way to fix this error? Down bellow you'll find the full error message it gave me. The specs for my Mac are (if they are helpful in any way): M1 Pro MBP 14" with 16GB Ram and 512GB SSD.
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?
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.

I have a SPFx React application where I am printing the HTML page content using the javascript default window.print() functionality. Once I save the page as pdf from the print preview window and open it using Adobe Acrobat, the links(for eg -> Google) within the content are not clickable and appearing as plain text.
I have tried to print random pages post searching with any keywords in Google and saved the files as pdfs, but, unfortunately, the links are still not clickable there as well.
To check whether it is an Adobe Acrobat issue, I have performed the same print functionality from Android devices and shared the pdf file across the iOS devices and in that case, when opened using Adobe Acrobat, the links are appearing to be clickable.
I am wondering whether it is something related to how the default print functionality works for iPadOS and iOS devices. Any insights on this would be really helpful. Thanks!!!
Note: The links are clickable for MacOS as well as for Windows.

Imagine a native macOS app that acts as a "launcher" for a Java game.** For example, the "launcher" app might use the Swift Process API or a similar method to run the java command line tool (lets assume the user has installed Java themselves) to run the game.
I have seen How to Enable Game Mode. If the native launcher app's Info.plist has the following keys set:
LSApplicationCategoryType set to public.app-category.games
LSSupportsGameMode set to true (for macOS 26+)
GCSupportsGameMode set to true
The launcher itself can cause Game Mode to activate if the launcher is fullscreened. However, if the launcher opens a Java process that opens a window, then the Java window is fullscreened, Game Mode doesn't seem to activate. In this case activating Game Mode for the launcher itself is unnecessary, but you'd expect Game Mode to activate when the actual game in the Java window is fullscreened.
Is there a way to get Game Mode to activate in the latter case?
** The concrete case I'm thinking of is a third-party Minecraft Java Edition launcher, but the issue can also be demonstrated in a sample project (FB13786152). It seems like the official Minecraft launcher is able to do this, though it's not clear how. (Is its bundle identifier hardcoded in the OS to allow for this? Changing a sample app's bundle identifier to be the same as the official Minecraft launcher gets the behavior I want, but obviously this is not a practical solution.)
In swipe-driven games, a first downward swipe starting near the home indicator can trigger Reachability, even when using preferredScreenEdgesDeferringSystemGestures = .bottom and prefersHomeIndicatorAutoHidden = true. This causes the app to slide down to half screen and breaks gameplay. Please consider an API to temporarily defer Reachability while a custom gesture is active (similar to existing system gesture deferral), without disabling accessibility globally.
Environment:
Devices: iPhones with Home Indicator (Face ID)
Why this matters:
Bottom-origin swipes are core in many games (flick shots, slingshot, physics toss, bottom sheets). Current workarounds degrade UX and discoverability, and players still accidentally trigger Reachability.

Hello,
We are experiencing an issue with apparent lag or latency when interacting with objects in Unity using the XR Interaction Toolkit. Even when interactables are configured with the Movement Type set to Instantaneous, objects exhibit a noticeable delay when following hand movement. This issue is particularly apparent when the hand moves at higher speeds.
We would like to know: is any additional configuration required, or is there something else we need to do to resolve this?
Thank you very much for your assistance.
