I plan to create a simple motion graphics software for macOS that animates text, basic shapes, and handles audio. I'll use SwiftUI for the UI.
What are the commonly used technologies for rendering animated graphics? Core Animation is suitable for UI animations but not for exporting and controlling UI animations.
Basic requirements:
Timeline user interface
Animation of text and basic shapes
Viewer in SwiftUI GUI with transport control (play, pause, scrub, …)
Export to video file
Is Metal or Core Graphics typically used directly? I want to keep it as simple as possible.

I’m trying to build my project using Unreal Engine 5.4 for iOS. I use SocketIO to connect to the backend. The plugin SocketIOClient version 2.8.0, is used for this.
When trying to connect to the socket, a crash occurs. This only happens on iOS, only in Distribution builds, and only on Unreal 5.4. There are no problems on Unreal 5.2. Callstack:
crashlog.crash
The callstack may be slightly different, but the problem is always when allocating or deallocating memory. I suspect that this may be a race condition and is related to some peculiarities of working with memory on iOS. There are also several similar issues in the plugin repository, for example this one.
I tried using other versions of plugin, other versions of xcode, tried to build socket io using both c++20 and c++17, nothing helps. Does anyone know what can be done about this?

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!

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?

There is a Android Dynamic Performance Framework,
https://developer.android.com/games/optimize/adpf which allows you to monitor device's thermal state and send performance hints to the OS, describing current workload.
This helps to consume resources effectively, while having target performance. As I can see from tracing and profiling, hints help OS scheduler to switch tasks between cores more effectively - this helps to reach performance stability between multiple runs.
I wonder, is there anything similar for iOS platform?
__builtin_ia32_cvtb2mask512() is the GNU C builtin for vpmovb2m k, zmm.
The Intel intrinsic for it is _mm512_movepi8_mask.
It extracts the most-significant bit from each byte, producing an integer mask.
The SSE2 and AVX2 instructions pmovmskb and vpmovmskb do the same thing for 16 or 32-byte vectors, producing the mask in a GPR instead of an AVX-512 mask register. (_mm_movemask_epi8 and _mm256_movemask_epi8).
I would like an implementation for ARM that is faster than below
I would like an implementation for ARM NEON
I would like an implementation for ARM SVE
I have attached a basic scalar implementation in C. For those trying to implement this in ARM, we care about the high bit, but each byte's high bit (in a 128bit vector), can be easily shifted to the low bit using the ARM NEON intrinsic: vshrq_n_u8(). Note that I would prefer not to store the bitmap to memory, it should just be the return value of the function similar to the following function.
#define _(n) __attribute((vector_size(1<<n),aligned(1)))
typedef char V _(6); // 64 bytes, 512 bits
typedef unsigned long U;
#undef _
U generic_cvtb2mask512(V v) {
U mask=0;int i=0;
while(i<64){
// shift mask by 1 and OR with MSB of v[i] byte
mask=(mask<<1)|((v[i]&0x80)>>7);
i++;}
return mask;
}

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 create an empty metadata, and set the HDRGainMapHeadroom at xxx. However the final returned mutableMetadata doesn't contain the HDRGainMap:HDRGainMapVersion or HDRGainMap:HDRGainMapHeadroom. But iio:hasXMP exist.
why? Is that the reason that the namespace HDRGainMap is private?
func createHDRGainMapMetadata(version: Int, headroom: Double) -> CGImageMetadata? {
// Create a mutable metadata object
let mutableMetadata = CGImageMetadataCreateMutable()
// Define the namespace for HDRGainMap
let namespace = "HDRGainMap"
let xmpKeyPath = "iio:hasXMP"
let xmpValue = String(true)
// Set the HDRGainMapVersion item
let versionKeyPath = "\(namespace):HDRGainMapVersion"
let versionValue = String(version)
// Set the version value
let xmpSetResult = CGImageMetadataSetValueWithPath(mutableMetadata, nil, xmpKeyPath as CFString, xmpValue as CFString)
if xmpSetResult == false {
print("Failed to set xmp")
}
// Set the version value
let versionSetResult = CGImageMetadataSetValueWithPath(mutableMetadata, nil, versionKeyPath as CFString, versionValue as CFString)
if versionSetResult == false {
print("Failed to set HDRGainMapVersion")
}
// Set the HDRGainMapHeadroom item
let headroomKeyPath = "\(namespace):HDRGainMapHeadroom"
let headroomValue = String(headroom)
// Set the headroom value
let headroomSetResult = CGImageMetadataSetValueWithPath(mutableMetadata, nil, headroomKeyPath as CFString, headroomValue as CFString)
if headroomSetResult == false {
print("Failed to set HDRGainMapHeadroom")
}
return mutableMetadata

Hi all,
I have been trying to get Apple's assistive touch's snap to item to work for a unity game built using Apple's Core & Accessibility API. The switch control recognises these buttons however, eye tracking will not snap to them. The case in which it needs to snap is when an external eye tracking device is connected and utilises assistive touch & assistive touch's snap to item.
All buttons in the game have a AccessibilityNode with the trait 'Button' on them & an appropriate label, which, following the documentation and comments on the developer forum, should allow them to be recognised by snap to item.
This is not the case, devices (iPads and iPhones) do not recognise the buttons as a snap to target.
Does anyone know why this is the case, and if this is a bug?
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!

The result video is not in correct color as the original video. It turns out too bright. If I play around with attachment values, it can be either too dim or too bright but not exactly proper as the original video. What am I missing in my setup? I did find that kCVPixelFormatType_4444AYpCbCr16 can produce proper video output but then I can't convert it to CIImage and so I can't do the CIImage operations that I need. Mainly cropping and resizing the CIImage
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"];

ExceptionType severity;
description = MagickGetException(wand, &severity);

return;
}
if (MagickSetFormat(wand, "JP2") == MagickFalse) {

return;
}
NSLog(@"Image successfully converted.");

We as a team of engineers work on an app intended to visualize medical images. The type of situations where the app is used involves time critical decision making for acute clinical conditions. Stability of the app and performance are of utmost importance and can directly help timely treatment action. The app we are developing uses multiple libraries and tools like vtk, webgl, opengl, webkit, gl-matrix etc.
The problem specifically can be described as follows, it has been observed that when 3D volume is rendered in the app and we try to rotate the volume the rotation is slow, unresposive and laggy. Specifically, we have noticed that iOS 18.1 the volume rotation is much smoother as compared to latest iOS 18.2. Eariler, we have faced somewhat similar issue with iOS 17 but it got improved in iOS 18.1. This performance regression is affecting the user experience in our healthcare application.
We have taken reference from the cornerstone.js code and you can reproduce the issue using the following example: https://www.cornerstonejs.org/live-examples/volumeviewport3d
Steps to Reproduce:
Load the above mentioned test example on an iPhone running version 18.2 using safari.
Perform volume rendering using the provided dataset.
Measure the time taken by volume for each rotate or drag action.
Repeat the same steps on an iPhone running version 18.1 for comparison.
Additional Information:
Device Model Tested:
iPhone12, iPhone13, iPhone14
iOS Version With Issue:
18.2
18.3(Beta)
I would appreciate any insights or suggestions on how to address this performance regression. If additional information is needed, please let me know.
Thank you.

After many former OS and Xcode updates, my Game Controller Swift code generates a "DIS-CONNECTED" MESSAGE.

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.
