I've made a simple command line app that requires Screen recording permission. When I ran it from Xcode, it prompts for a permission and once I allowed it from the settings, it runs well. #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <CoreGraphics/CGDisplayStream.h> int main() { printf("# Start #\n"); if (CGPreflightScreenCaptureAccess()) { printf("# Permitted.\n"); } else { printf("# Not permitted.\n"); if (CGRequestScreenCaptureAccess() == false) { printf("# CGRequestScreenCaptureAccess() returning false\n"); } } size_t output_width = 1280; size_t output_height = 720; dispatch_queue_t dq = dispatch_queue_create("com.domain.screengrabber", DISPATCH_QUEUE_SERIAL); CGError err; CGDisplayStreamRef sref = CGDisplayStreamCreateWithDispatchQueue( 1, output_width, output_height, 'BGRA', NULL, dq, ^( CGDisplayStreamFrameStatus status, uint64_t time, IOSurfaceRef frame, CGDisplayStreamUpdateRef ref ) { printf("Got frame: %llu, FrameStatus:%d \n", time, status); } ); err = CGDisplayStreamStart(sref); if (kCGErrorSuccess != err) { printf("Error: failed to start streaming the display. %d\n", err); exit(EXIT_FAILURE); } while (true) { usleep(1e5); } CGDisplayStreamStop(sref); printf("\n\n"); return 0; } Now I want to execute this from terminal, so I went to the build folder and typed the app name. cd /Users/klee/Library/Developer/Xcode/DerivedData/ScreenStreamTest-ezddqbkzhndhakadslymnvpowtig/Build/Products/Debug ./ScreenStreamTest But I am getting following output without any prompt for permission. # Start # # Not permitted. # CGRequestScreenCaptureAccess() returning false Error: failed to start streaming the display. 1001 Is there a something I need to consider for this type of command line app?

I had no luck to compile a sample code provided by apple with Xcode 16.0 beta 5. ScreenCaptureKit demo (https://developer.apple.com/documentation/screencapturekit/capturing_screen_content_in_macos) The part it is failling is, streamOutput.capturedFrameHandler = { continuation.yield($0) } And the error message is Sending '$0' risks causing data races Task-isolated '$0' is passed as a 'sending' parameter; Uses in callee may race with later task-isolated uses Please enlighten me why this is an issue and how to avoid? Thanks in advance!

Hello, I am trying to make use of SCContentSharingPicker for my app and I wonder how I can detect a close event of SCContentSharingPicker. I could open the picker screen with following simple code: SCContentSharingPicker.shared.isActive = true SCContentSharingPicker.shared.add(self) SCContentSharingPicker.shared.present() And I closed it with "Cancel" button located at the top right corner. Initially I was expecting to get a event through an observer like below but realised that it's called when a stream is canceled. extension ContentPickerButton: SCContentSharingPickerObserver { func contentSharingPicker(_ picker: SCContentSharingPicker, didCancelFor stream: SCStream?) { logger.info("Picker canceled for stream \(stream)") } I would like to get a picker close event so that I can deactivate the picker. (Otherwise, camera icon will stay alive at the tray.) How do we get a close event?

How do we open Keyboard Viewer programatically? I am working on Sonoma Mac Application. I could open "Emoji & Symbols" programatically as follows. NSArray *sources = (__bridge NSArray*)TISCreateInputSourceList(nil, false); TISInputSourceRef keyboardViewer = (__bridge TISInputSourceRef)[sources objectAtIndex: 2]; // "Emoji & Symbols" is the 3rd one. So 2. TISSelectInputSource(keyboardViewer); CFRelease((CFTypeRef)sources); After some searching, Keyboard Viewer could be opened with similiar approach with above in the old previous version of MacOS. I have a strong feeling there is a way to bring up the keyboard because we can bring up "Emoji & Symbols". I mean, why would apple prevent us to show Keyboard Viewer. Any idea?
