Hello everyone, I'm working on a screen recording app using ScreenCaptureKit and I've hit a strange issue. My app records the screen to an .mp4 file, and everything works perfectly until the .captureMicrophone is false In this case, I get a valid, playable .mp4 file. However, as soon as I try to enable the microphone by setting streamConfig.captureMicrophone = true, the recording seems to work, but the final .mp4 file is corrupted and cannot be played by QuickTime or any other player. This happens whether capturesAudio (app audio) is on or off. I've already added the "Privacy - Microphone Usage Description" (NSMicrophoneUsageDescription) to my Info.plist, so I don't think it's a permissions problem. I have my logic split into a ScreenRecorder class that manages state and a CaptureEngine that handles the SCStream. Here is how I'm configuring my SCStream: ScreenRecorder.swift // This is my main SCStreamConfiguration private var streamConfiguration: SCStreamConfiguration { var streamConfig = SCStreamConfiguration() // ... other HDR/preset config ... // These are the problem properties streamConfig.capturesAudio = isAudioCaptureEnabled streamConfig.captureMicrophone = isMicCaptureEnabled // breaks it if true streamConfig.excludesCurrentProcessAudio = false streamConfig.showsCursor = false if let region = selectedRegion, let display = currentDisplay { // My region/frame logic (works fine) let regionWidth = Int(region.frame.width) let regionHeight = Int(region.frame.height) streamConfig.width = regionWidth * scaleFactor streamConfig.height = regionHeight * scaleFactor // ... (sourceRect logic) ... } streamConfig.pixelFormat = kCVPixelFormatType_32BGRA streamConfig.colorSpaceName = CGColorSpace.sRGB streamConfig.minimumFrameInterval = CMTime(value: 1, timescale: 60) return streamConfig } And here is how I'm setting up the SCRecordingOutput that writes the file: ScreenRecorder.swift private func initRecordingOutput(for region: ScreenPickerManager.SelectedRegion) throws { let screeRecordingOutputURL = try RecordingWorkspace.createScreenRecordingVideoFile( in: workspaceURL, sessionIndex: sessionIndex ) let recordingConfiguration = SCRecordingOutputConfiguration() recordingConfiguration.outputURL = screeRecordingOutputURL recordingConfiguration.outputFileType = .mp4 recordingConfiguration.videoCodecType = .hevc let recordingOutput = SCRecordingOutput(configuration: recordingConfiguration, delegate: self) self.recordingOutput = recordingOutput } Finally, my CaptureEngine adds these to the SCStream: CaptureEngine.swift class CaptureEngine: NSObject, @unchecked Sendable { private(set) var stream: SCStream? private var streamOutput: CaptureEngineStreamOutput? // ... (dispatch queues) ... func startCapture(configuration: SCStreamConfiguration, filter: SCContentFilter, recordingOutput: SCRecordingOutput) async throws { let streamOutput = CaptureEngineStreamOutput() self.streamOutput = streamOutput do { stream = SCStream(filter: filter, configuration: configuration, delegate: streamOutput) // Add outputs for raw buffers (not used for file recording) try stream?.addStreamOutput(streamOutput, type: .screen, sampleHandlerQueue: videoSampleBufferQueue) try stream?.addStreamOutput(streamOutput, type: .audio, sampleHandlerQueue: audioSampleBufferQueue) try stream?.addStreamOutput(streamOutput, type: .microphone, sampleHandlerQueue: micSampleBufferQueue) // Add the file recording output try stream?.addRecordingOutput(recordingOutput) try await stream?.startCapture() } catch { logger.error("Failed to start capture: \(error.localizedDescription)") throw error } } // ... (stopCapture, etc.) ... } When I had the .captureMicrophone value to be false, I get a perfect .mp4 video playable everywhere, however, when its true, I am getting corrupted video which doesn't play at all :-

Looks like is something to do with the code and that is why my images are distorted. please help me get to the right person to help me get this issue resolved

Hello, I am experiencing an issue with programmatically capturing a GPU trace using MTLCaptureManager. The .gputrace file that is generated appears to be corrupted, and I'm looking for guidance or a solution. Description of the Problem: I am using MTLCaptureManager.sharedCaptureManager to capture a Metal frame and save it to disk. The generated .gputrace file is consistently reported as 0 bytes in size by the file system. Crucially, when I compress this 0-byte .gputrace file into a .zip archive, the resulting archive contains the full, expected data. After unzipping, the file can be opened and viewed correctly in Xcode. However,When inspecting the file's contents using NSFileManager in Objective-C (treating it as a directory), the internal structure is different from a .gputrace file captured directly from Xcode's Metal Debugger. capture in xcode capture in file Finally,When capturing multiple frames programmatically, the first captured frame contains valid buffer data. However, for subsequent frames (starting from the second frame), the corresponding buffer contents are all zero-filled. Frame 1: All MTLBuffer data is correctly captured and populated. Frame 2 and onward: The same MTLBuffer objects are present in the trace, but their contents are entirely 0 (i.e., the data is not captured or is corrupted). In this case, the on-screen display is normal, but the captured frame is incorrect. The frame captured directly in Xcode is also correct. Only the frame captured to a file is abnormal.

Hello, I'm tracking down a bug where useResource doesn't seem to apply proper synchronization when a resource is produced by the render pass then consumed by the compute pass, but when I use MTLFence between the to signal and wait between the render/compute encoders, the artifact goes away. The resource is created with MTLHazardTrackingModeTracked and useResource is called on the compute encoder after the render pass. Metal API Validation doesn't report any warnings/errors. Am I misunderstanding the difference between the two APIs? I dug through the Metal documentation and it looks like useResource should handle synchronization given the resource has MTLHazardTrackingModeTracked but on the other hand, MTLFence should be used to ensure proper synchronization between command encoders. Can someone can clarify the difference between the two APIs and when to use them.

I am trying to simulate a paste command and it seems to not want to paste. It worked at one point with the same code and now is causing issues. My code looks like this: ` func simulatePaste() { guard let source = CGEventSource(stateID: .hidSystemState) else { print("Failed to create event source") return } let keyDown = CGEvent(keyboardEventSource: source, virtualKey: CGKeyCode(9), keyDown: true) let keyUp = CGEvent(keyboardEventSource: source, virtualKey: CGKeyCode(9), keyDown: false) keyDown?.flags = .maskCommand keyUp?.flags = .maskCommand keyDown?.post(tap: .cgAnnotatedSessionEventTap) keyUp?.post(tap: .cgAnnotatedSessionEventTap) print("Simulated Cmd + V") } I know that there is some issues around permissions and so in my Info.plist I have this: <string>NSApplication</string> <key>NSAppleEventsUsageDescription</key> <string>This app requires permission to send keyboard input for pasting from the clipboard.</string> I have also disabled sandbox. It does ask me if I want to give the app permissions but after approving it, it still doesn't paste.

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.

Description: In the official visionOS 26 Hover Effect sample code project , I encountered an issue where the event.trackingAreaIdentifier returned by onSpatialEvent does not reset as expected. Steps to Reproduce: Select an object with trackingAreaID = 6 in the sample app. Look at a blank space (outside any tracking area) and perform a pinch gesture . Expected Behavior: The event.trackingAreaIdentifier should return 0 when interacting with a non-tracking area. Actual Behavior: The event.trackingAreaIdentifier still returns 6, even after restarting the app or killing the process. This persists regardless of where the pinch gesture is performed

Hello! Brand new to the Apple developer community, so, hello everyone! I'm a game developer, we just launched our first game on PC and I'm looking to port it to ios. Time is something I'm kind of short on, and I hear it takes some jumping through hoops to get the know-how to port something to mobile. Any good sites you'd recommend for finding programmers to port your game? It's fairly simple - just a visual novel. Any and all suggestions welcome! All the best! Elijah

Hi, I’m learning MAUI and was trying to use VNDocumentCameraViewController provided by Vision Kit to scan documents and it is working fine but I realized that I was not able to customize some of the options provided by default like, disabling the auto scan option. Is there any way to disable the auto scan option or are there any other alternatives with the same founctionalities as VNDocumentCameraViewController that are more customizable?

Hi All! I'm being asked to migrate an app which utilizes iCloud KVS (Key Value Storage). This ability is a new-ish feature, and the documentation about this is sparse [1]. Honestly, the entire documentation about the new iCloud transfer functionality seems to be missing. Same with Game Center / GameKit. While the docs say that it should work, I'd like to understand the process in more detail. Has anyone migrated an iCloud KVS app? What happens after the transfer goes through, but before the first release? Do I need to do anything special? I see that the Entitlements file has the TeamID in the Key Value store - is that fine? <key>com.apple.developer.ubiquity-kvstore-identifier</key> <string>$(TeamIdentifierPrefix)$(CFBundleIdentifier)</string> Can someone please share their experience? Thank you! [1] https://developer.apple.com/help/app-store-connect/transfer-an-app/overview-of-app-transfer

Hello, Thank you for attending today’s Metal & game technologies group lab at WWDC25! We were delighted to answer many questions from developers and energized by the community engagement. We hope you enjoyed it and welcome your feedback. We invite you to carry on the conversation here, particularly if your question appeared in Slido and we were unable to answer it during the lab. If your question received feedback let us know if you need clarification. You may want to ask your question again in a different lab e.g. visionOS tomorrow. (We realize that this can be confusing when frameworks interoperate) We have a lot to learn from each other so let’s get to Q&A and make the best of WWDC25! 😃 Looking forward to your questions posted in new threads.

I have a Mac Studio 2023 M2 Max Running Sonoma 14.6.1 Developing in XCode 16.1 It seems that the NSScreen frame settings may be incorrect. The frame settings received from NSScreen.screens don't seem to match up with the Desktop arrangement settings in the Settings. Apologies in advance for this long post! for screen in NSScreen.screens { let name = screen.localizedName Globals.logger.debug("Globals initializeScreens - screen \(i) '\(name, privacy: .public)'") Globals.logger.debug("Globals initializeScreens - '\(screen.debugDescription, privacy: .public)'") } This is what I receive in the log: Globals initializeScreens - '<NSScreen: 0x600000ef4240; name="PHL 346E2C"; backingScaleFactor=1.000000; frame={{0, 0}, {3440, 1440}}; visibleFrame={{0, 0}, {3440, 1415}}>' Globals initializeScreens - screen 2 'Blackmagic (1)' Globals initializeScreens - '<NSScreen: 0x600000ef42a0; name="Blackmagic (1)"; backingScaleFactor=1.000000; frame={{-3840, 0}, {1920, 1080}}; visibleFrame={{-3840, 0}, {1920, 1055}}>' Globals initializeScreens - screen 3 'Blackmagic (4)' Globals initializeScreens - '<NSScreen: 0x600000ef4360; name="Blackmagic (4)"; backingScaleFactor=1.000000; frame={{-1920, 0}, {1920, 1080}}; visibleFrame={{-1920, 0}, {1920, 1055}}>' Globals initializeScreens - screen 4 'Blackmagic (2)' Globals initializeScreens - '<NSScreen: 0x600000ef43c0; name="Blackmagic (2)"; backingScaleFactor=1.000000; frame={{5360, 0}, {1920, 1080}}; visibleFrame={{5360, 0}, {1920, 1055}}>' Globals initializeScreens - screen 5 'Blackmagic (3)' Globals initializeScreens - '<NSScreen: 0x600000ef4420; name="Blackmagic (3)"; backingScaleFactor=1.000000; frame={{3440, 0}, {1920, 1080}}; visibleFrame={{3440, 0}, {1920, 1055}}>' It looks like the frame settings for Blackmagic (2) and Blackmagic (4) are switched. The setup has five monitors. Four are using the USB-C Digital AV Multiport Adapters. The output for these are streamed into a rack of A/V equipment using BlackMagic Design mini converters and monitors. My Swift application allows users to open four movies, one for each of the AV Adapters. The movies can then be played back in sync for later processing by the A/V equipment. Here are some screen captures that show my display settings. Blackmagic (1) and Blackmagic (2) are to the left of the main screen. Blackmagic (3) and Blackmagic(4) are to the right of the main screen. The desktop is hard to see but is correct. The wallpaper settings are all correct. The wallpaper is correctly ordered when displayed on the monitors. After opening the movies and using the NSScreen frame settings, the displays are incorrectly ordered. Test B and Test D are switched, which is what I would expect given the NSScreen frame values. Any ideas? I've tried re-arranging the desktops, rebooting, etc. but no luck. The code that changes the screen location is similar to this post on Stack Overflow public func setDisplay( screen: NSScreen ) { Globals.logger.log("MovieWindowController - setDisplay = \(screen.localizedName, privacy: .public)") Globals.logger.debug("MovieWindowController - setDisplay - '\(screen.debugDescription, privacy: .public)'") let dx = CGFloat(Constants.midX) let dy = CGFloat(Constants.midY) var pos = NSPoint() pos.x = screen.visibleFrame.midX - dx pos.y = screen.visibleFrame.midY - dy Globals.logger.debug("MovieWindowController - setDisplay - x = '\(pos.x, privacy: .public)', y = '\(pos.y, privacy: .public)'") window?.setFrameOrigin(pos) } The log show just what I would expect given the incorrect frame values. MovieWindowController - setDisplay = Blackmagic (1) MovieWindowController - setDisplay - '<NSScreen: 0x6000018e8420; name="Blackmagic (1)"; backingScaleFactor=1.000000; frame={{-3840, 0}, {1920, 1080}}; visibleFrame={{-3840, 0}, {1920, 1055}}>' MovieWindowController - setDisplay - x = '-3840.000000', y = '-12.500000' MovieWindowController - setDisplay = Blackmagic (2) MovieWindowController - setDisplay - '<NSScreen: 0x6000018a10e0; name="Blackmagic (2)"; backingScaleFactor=1.000000; frame={{5360, 0}, {1920, 1080}}; visibleFrame={{5360, 0}, {1920, 1055}}>' MovieWindowController - setDisplay - x = '5360.000000', y = '-12.500000' MovieWindowController - setDisplay = Blackmagic (3) MovieWindowController - setDisplay - '<NSScreen: 0x6000018cc8a0; name="Blackmagic (3)"; backingScaleFactor=1.000000; frame={{3440, 0}, {1920, 1080}}; visibleFrame={{3440, 0}, {1920, 1055}}>' MovieWindowController - setDisplay - x = '3440.000000', y = '-12.500000' MovieWindowController - setDisplay = Blackmagic (4) MovieWindowController - setDisplay - '<NSScreen: 0x6000018c9ce0; name="Blackmagic (4)"; backingScaleFactor=1.000000; frame={{-1920, 0}, {1920, 1080}}; visibleFrame={{-1920, 0}, {1920, 1055}}>' MovieWindowController - setDisplay - x = '-1920.000000', y = '-12.500000' Am I correct? I think this is driving me crazy! Thanks in advance! Edit: The mouse behavior is correct in moving across the displays!

I'm building a game with a client-server architecture. Using GKMatch.chooseBestHostingPlayer(_:) rarely works. When I started testing it today, it worked once at the very beginning, and since then it always succeeds on one client and returns nil on the other client. I'm testing with a Mac and an iPhone. Sometimes it fails on the Mac, sometimes on the iPhone. On the device that it succeeds on, the provided host can be the device itself or the other one.

In Xcode version 16.2 (16C5032a) I created: One [ScenekitApp] [File/New/Project/iOS/Game/Game Technology: SceneKit]. Three custom Frameworks [File/New/Project/iOS/Framework] [ASCSource.framework, ASCCommon.framework and ASCCoreData.framework]. In the four projects the [Minimum Deployments=iOS 15.0], [Swift version=6.0] and [BUILD_LIBRARY_FOR_DISTRIBUTION=Yes]. I directly installed the [Zip.framework] in [ASCSource.framework] without [pod init/pod install] and in the [General tab] [Frameworks, Libraries and Embeded Content] [Zip.framework Embed&Sign]. I installed the three frameworks [ASCSource.framework, ASCCommon.framework and ASCCoreData.framework] in [ScenekitApp] and everything works perfectly in Xcode version 16.2(16C5032a). I updated Xcode version 16.2(16C5032a) to Xcode version 16.3(16E140) and some errors in the SDKs were indicated.

I have an M1 Pro with a 16-core GPU. When I run a shader with 8193 threads, atomic_thread_fence is violated across the boundary between thread 8191 (the last thread in the 7th threadgroup) and 8192 (the first thread in the 9th threadgroup). I've attached the Metal and Swift files, but I'll repost the relevant kernel here. It's a function that launches N threads to iterate through a binary tree from the leaves, where the first thread to reach the parent terminates and the second one populates it with the sum of the nodes two children. // clang-format off void sum(device const int& size, device const int* __restrict__ in, device int* __restrict__ out, device atomic_int* visited, uint i [[thread_position_in_grid]]) { // clang-format on int val = in[i]; uint cur = (size + i - 1); out[cur] = val; atomic_thread_fence(mem_flags::mem_device, memory_order_seq_cst); cur = (cur - 1) / 2; int proceed = atomic_fetch_add_explicit(&visited[cur], 1, memory_order_relaxed); while (proceed == 1) { uint left = 2 * cur + 1; uint right = 2 * cur + 2; uint val_left = out[left]; uint val_right = out[right]; uint val_cur = val_left + val_right; out[cur] = val_cur; if (cur == 0) { break; } cur = (cur - 1) / 2; atomic_thread_fence(mem_flags::mem_device, memory_order_seq_cst); proceed = atomic_fetch_add_explicit(&visited[cur], 1, memory_order_relaxed); } } What I'm observing is that thread 8192 hits the atomic_fetch_add first and terminates, while thread 8191 hits it second (observes that thread 8192 had incremented it by 1) and proceeds into the loop. Thread 8191 reads out[16383] (which it populated with 8191) and out[16384] (which thread 8192 populated with 8192 prior to the atomic_thread_fence). Instead of reading 8192 from out[16384] though, it reads 0. Maybe I'm missing something but this seems like a pretty clear violation of the atomic_thread_fence which (I thought) was supposed to guarantee that the write from thread 8192 to out[16384] would be visible to any thread observing the effects of the following atomic_fetch_add. Is atomic_fetch_add not a store operation? Modifying it to an atomic_store or atomic_exchange still results in the bug. Adding another atomic_thread_fence between the atomic_fetch_add and reading of out also doesn't change anything. I only begin to observe this on grid sizes of 8193 and upwards. That's 9 threadgroups per grid, which I assume could be related to my M1 Pro GPU having 16 cores. Running the same example on an A17 Pro GPU doesn't show any of this behavior up through a tested grid size of 4194303 (2^22-1), at which point testing larger grid sizes starts to run into other issues so I can't test anything larger. Removing the atomic_thread_fences on both the M1 and A17 cause the test to fail at much smaller grid sizes, as expected. sum.metal main.swift

I am trying to convert a JPG image to a JP2 (JPEG 2000) format using the ImageMagick library on iOS. However, although the file extension is changing to .jp2, the format of the image does not seem to be changing. The output image is still being treated as a JPG file, and not as a true JP2 format. Here is the code (IBAction)convertButtonClicked:(id)sender { NSString *jpgPath = [[NSBundle mainBundle] pathForResource:@"Example" ofType:@"jpg"]; NSString *tempFilePath = [NSTemporaryDirectory() stringByAppendingPathComponent:@"Converted.jp2"]; MagickWand *wand = NewMagickWand(); if (MagickReadImage(wand, [jpgPath UTF8String]) == MagickFalse) { char *description; ExceptionType severity; description = MagickGetException(wand, &severity); NSLog(@"Error reading image: %s", description); MagickRelinquishMemory(description); return; } if (MagickSetFormat(wand, "JP2") == MagickFalse) { char *description; ExceptionType severity; description = MagickGetException(wand, &severity); NSLog(@"Error setting image format to JP2: %s", description); MagickRelinquishMemory(description); } if (MagickWriteImage(wand, [tempFilePath UTF8String]) == MagickFalse) { NSLog(@"Error writing JP2 image"); return; } NSLog(@"Image successfully converted."); } @end

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.

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 didn't find a suggestion box on Swift's website so I'll post it here. SwiftCharts are great but limited. I need more data on a single chart. Candlestick and OHLC type charts would be an excellent addition. Hopefully, influencers from Apple can make that happen. Thanks.
