I have a game built in Unreal Engine 5.6 which uses tilt motion controls to rotate an object. I've restricted the app to only run in portrait for iPhone, and everything works fine, however for iPad I've had a few issues relating to multitasking and I can't seem to solve it.
Forcing the app to portrait only still allows the app to run in landscape mode, but shows black bars either side of the game, and the axes for the motion controls are incorrect. X becomes Y and Y becomes X, and there's no way for my app to know which orientation it is because the container is still technically portrait.
Allowing my game to run in all orientations makes the whole app more presentable, it doesn't add black bars and the game is still functional and I'm able to map the controls correctly because the game knows it's landscape rather than portrait.
The problem with allowing my app to run in landscape mode is if multitasking is enabled on the ipad, you can resize the app to be portrait, and then I run into the same problem again where the game thinks it's portrait mode and all of the axes are wrong again.
I tried getting the true orientation of the device rather than the scene, but the game is intended to be played flat so instead of returning the orientation of the OS the orientation is FaceUp, which doesn't help.
I need to either disable multitasking or find a way of getting the orientation of the OS (not the scene or the device). I haven't found how to get the OS orientation so I've been trying to disable multitasking.
I've got Requires Fullscreen true and UIApplicationSupportsMultipleScreens false in my info.plist but my iPad still seems to allow the window to be resized in landscape view. Opening the IOS workspace of my project Requires Fullscreen is ticked but under that it says "Supports Multiple Windows" and the arrow button next to it takes my to my info.plist values, but no indication of how I can change it.
I'm using Unreal Engine 5.6 and Xcode 16.0. Xcode is old I know, but this version of unreal engine doesn't seem to support any newer.

I have been trying to run an open source Windows executable that I would like to help porting to macOS using the Game Porting Toolkit but I stumbled on an issue quite early in the application lifecycle.
It looks like the funtion GetThreadDpiHostingBehavior is missing in USER32.dll
Has anyone any idea how to solve that?
During the startup, it fails with the following error:
TiXL crashed. We're really sorry.
The last backup was saved Unknown time to...

We used below method to resize image while compress the image,
Below method is correct or need to do the correction in method or "CGBitmapContextCreate"
-(UIImage *)resizeImage:(UIImage *)anImage width:(int)width height:(int)height
{
CGImageRef imageRef = [anImage CGImage];
CGImageAlphaInfo alphaInfo = CGImageGetAlphaInfo(imageRef);
if (alphaInfo == kCGImageAlphaNone)
alphaInfo = kCGImageAlphaNoneSkipLast;
CGContextRef bitmap = CGBitmapContextCreate(NULL, width, height, CGImageGetBitsPerComponent(imageRef), 4 * width, CGImageGetColorSpace(imageRef), alphaInfo);
CGContextDrawImage(bitmap, CGRectMake(0, 0, width, height), imageRef);
CGImageRef ref = CGBitmapContextCreateImage(bitmap);
UIImage *result = [UIImage imageWithCGImage:ref];
CGContextRelease(bitmap);
CGImageRelease(ref);
return result;
}
I have code available at http://sf.net/p/silverhawk-curses/ and http://sf.net/p/silverhawkTerminal/
Does anyone know if we will be able to airplay content from another Apple device, say an iPad or iPhone to the Vision Pro?
Does anyone know why the following call fails?
CGPDFOperatorTableSetCallback(operatorTable, "ID", &callback);
The PDF specification seems to indicate that ID is an operator?
BTW what is the proper topic/subtopic for questions about Quartz? Wasn't sure what topic on the new forums to post this under.

Hi, I have a full screen iOS game. In the Simulator, preferredScreenEdgesDeferringSystemGestures works well to prevent a drag down from the top of the full-screen play area from immediately opening the Notification Center. (You got a tab, and had to swipe down on it.) But at least on my device, when testing, unlike in Simulator, Notification Center opens immediately when I swipe down from the top. Any suggestions?

I am making a SpriteKit game and I am trying to change the cursor image from the default pointer to a png image that I have imported into the project, but it’s not really working. when I run the project I can see the cursor image change for a brief second and then return to the default image. Here is my code:
print(NSCursor.current)
if let image = NSImage(named: customImage) {
print("The image exists")
cursor = NSCursor(image: image, hotSpot: .zero)
cursor.push()
print(cursor)
}
print(NSCursor.current)
The above code is all contained in the didMove(:) function in GameScene. From the print statements I can see that the memory address of the NSCursor.current changes to that of cursor. HOWEVER, in the mouseMoved(:) call back function I print out the mouse location and the current cursor. I can see from these print stamens that the cursor memory address has again changed and no longer matches the custom cursor address… so I am not sure what is going on…
Also, fyi the cursor is a global property within game scene so it should persist. Also, image is not nil. This is verified by the print statements I see
Thanks
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

Hello, I am making a project in SDL, and with that I am using SDL_Image. I am doing all of this on Xcode.
I've been able to initialize everything just fine, but issues spring up when I try to load an image.
When I give the code a path to look for an image:
Unable to load image! IMG_Error: Couldn't open [Insert image path here]: Operation not permitted
I get that error.
Keep in mind "Unable to load image" is a general error I put in the code should loading said image fail, the specific error which I called with IMG_GetError() is what we really need to know.
I've seen before that this might occur if a program does not have full disk access. Because of this, I've tried giving Xcode full disk access, but this didn't work and I still got the same error.
macOS 15.2, MBP M1, built-in display.
The following code produces a line outside the bounds of my clipping region when drawing to CGLayers, to produce a clockwise arc:
CGContextBeginPath(m_s.outContext);
CGContextAddArc(m_s.outContext, leftX + radius, topY - radius, radius, -startRads, -endRads, 1);
CGContextSetRGBStrokeColor(m_s.outContext, col.fRed(), col.fGreen(), col.fBlue(), col.fAlpha());
CGContextSetLineWidth(m_s.outContext, width);
CGContextStrokePath(m_s.outContext);
Drawing other shapes such as rects or ellipses doesn't cause a problem.
I can work around the issue by bringing the path back to the start of the arc:
CGContextBeginPath(m_s.outContext);
CGContextAddArc(m_s.outContext, leftX + radius, topY - radius, radius, -startRads, -endRads, 1);
// add a second arc back to the start
CGContextAddArc(m_s.outContext, leftX + radius, topY - radius, radius, -endRads, -startRads, 0);
CGContextSetRGBStrokeColor(m_s.outContext, col.fRed(), col.fGreen(), col.fBlue(), col.fAlpha());
CGContextSetLineWidth(m_s.outContext, width);
CGContextStrokePath(m_s.outContext);
But this does appear to be a bug.
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?
Hola. At this point, I'm at my wit's end because I've tried EVERYTHING just to be able to play a single game on my Mac, but the new update makes it impossible.
So I'm just gonna ask for one game: I've been trying to play Stardew Valley, modded with SMAPI, for a week now. Despite playing the game with mods for almost 2 years, OS is refusing to open the game because SMAPI "contains malware". I tried reinstalling the mod, but no dice. It just automatically deletes the terminal and blocks the game from opening.
You can imagine my frustration because the mod has been 100% safe for 2 years. No option to "Open Anyway" in Security Settings, either. I have no say in this. I've tried code signing it in Terminal (three times). Also no dice. Followed these two forums.

NOTHING. Please tell me there's a way to override this??? Just let me install malware on my computer!😭

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.
Issue Summary:
In our Flutter application, we utilize Tencent's TRTC API for voice and video communication. While the broadcast functionality operates correctly on Android, it fails to respond on iOS devices. Attempting to initiate a broadcast results in no action, and long-pressing the broadcast button does not reveal the broadcast extension.
Steps to Reproduce:
Add Broadcast Upload Extension:
In Xcode, navigate to File > New > Target.
Select Broadcast Upload Extension and add it to the project.
2. Build the Project:
Attempt to build the project.
Encounter the error: "Cycle inside Runner; building could produce unreliable results."
3. Resolve Build Cycle Error:
Go to the project’s Build Phases.
Locate the Embed App Extensions phase.
Move Embed App Extensions just below Copy Bundle Resources.
Ensure the Copy only when installing option is selected.
Rebuild the project; the cycle error is resolved.
4.Test Broadcast Functionality:
Install the app on an iOS device.
Tap the broadcast button; observe no response.
Long-press the broadcast button in the top right hand scroll down menu; the broadcast extension is not listed.
5. Isolate the Issue:
Create a new Flutter project.
Repeat the above steps to add the broadcast upload extension.
The issue persists: broadcast functionality remains unresponsive on iOS.
Like many folks here, I've recently attempted to build Apple's Game Porting Toolkit on my machine and ran into compiler errors, but instead of going the usual route of downloading the prebuilt package (kindly provided by GCenX), I decided to see if I could force it to build (since it was obviously buildable at some point). Down below is the list of things I had to do to make it work.
Disclaimer: There are several dirty hacks I had to attempt to force the system to do what I needed. Use at your own risk.
Don't forget to run all brew commands from a Rosetta prompt:
arch -x86_64 zsh
Install openssl
This one is easy. Just run
brew tap rbenv/tap
brew install rbenv/tap/openssl@1.1
Install Command Line Tools 15.1
This specific version is required since newer versions come with the linker that is not compatible with the custom compiler (game-porting-toolkit-compiler) that GPTK is using. However, by default 15.1 tools won't install on Sequoia since the installer complains that macOS version is too new. Obviously, Apple has their reasons to not allow this, but all we need is a compiler which should be mostly indifferent to the OS version.
To trick the installer, we need to change OS requirement of the installer package. You can do it in four easy steps:
Copy Command Line Tools.pkg from the mounted Command_Line_Tools_for_Xcode_15.1.dmg to some other directory.
Expand the installer package:
pkgutil --expand "Command Line Tools.pkg" CLT
You might be prompted to install Command Line Tools when you call pkgutil, just install any version.
Go to the newly created CLT folder and edit the Distribution file (it may appear as executable but it's just an xml). You would want to change allowed-os-versions to something greater than 15. Removing this section altogether might also work.
When done, re-wrap the package:
pkgutil --flatten CLT "Command Line Tools 2.pkg"
Congratulations, now you should be able to install 15.1 tools on your OS! If you had to install newer Command Line Tools for pkgutil, delete them before installing 15.1:
sudo rm -rf /Library/Developer/CommandLineTools
Next step is to make Homebrew accept the outdated 15.1 tools, as by default it'll complain that they're outdated or corrupted. To shut it up, open
/usr/local/Homebrew/Library/Homebrew/extend/os/Mac/diagnostic.rb
and remove references to check_if_supported_sdk_available from a couple of fatal build check collections.
Note - by default, Homebrew will auto-update on any invocation, which will overwrite any changes you've made to its internals. To disable this behavior, before running any brew commands in the terminal, run
export HOMEBREW_NO_AUTO_UPDATE=1
After these manipulations, Homebrew might still complain about outdated Command Line Tools, but it won't be a fatal error anymore.
Finally, we need to downgrade MinGW to 11.0.1, since the latest version spits out compiler errors when compiling Wine. Unfortunately, Homebrew does a bad job tracking versions of MinGW, so there is no automatic way to do it. Instead, you have to manually download and install old MinGW 11.0.1 formula from the Homebrew git repository. I used the commit from Sep 16, 2023:
https://github.com/Homebrew/homebrew-core/blob/b95f4f9491394af667943bd92b081046ba3406f2/Formula/m/mingw-w64.rb
Download the file above, save it in your current working directory, and then run
brew install ./mingw-w64.rb
If you had a newer version of MinGW already installed from the previous build attempts, you can unlink it before installing the one above:
brew unlink mingw-w64
With Command Line Tools 15.1 and MinGW 11.0.1 you should now be able to build GPTK without errors:
brew -v install apple/apple/game-porting-toolkit
In the end, steps above worked for me, although more things could break in the future. I'm leaving the instructions here just to show that it's still possible to build GPTK manually instead of relying on third parties, but with all the hoops I had to jump through I can't really recommend it.
Our application is trying to read all resolutions of an external monitor. We have observed that, for the external monitor there is a mismatch in resolution list in our application and the resolution list in system settings. We are using the apple API "CGDisplayCopyAllDisplayModes" to read the resolutions.
I have an app that uses GameController to read the inputs of a connected JoyCon. However, the controller also interacts with the OS.
For example, when I press the Home button on the controller, it brings me to the home of my Vision Pro.
Is it possible to disable this interaction while still being able to read the controller inputs inside my app?
