I have to guess which command queue is the one I want to debug in Xcode here: I have label set, but it doesn't seem to affect this part of Xcode.

Hi, I have a CPP project, that I need to connect to the running program in order to debug. But the "Attach to process" option doesn't show any processes, or "Attach to process by PID or Name..." option is inactive. This Is how it looks... What could be the issue? These are my debug settings. If you need any other settings, leave a note and I'll upload

Dear Senior Developer, I come to you at a time where I am lost. Over the last 2-3 months, I have noticed a series of crashes occuring on my app. This all started randomly and has now been a regular occurence. Usually, I would receive some detail as it relates to some class or view that is causing this error but now the only details I have is it relates to a UiViewController dealloc even though I am using SwiftUI. Below I have attached the stack trace from firebase crash analytics. I have spent months on this and I am asking for the help of someone much more senior and knowledable to assist me in this regard. Thanks again for your help and I await your response. I am also willing to share my screen LIVE to help you help me identify this issue. manny.GoblinTools_issue_bfd18ee65a92b459d4ecef3475a9ec34_crash_session_032166c28b8c4764b13a6fdca636d2d6_DNE_0_v2_stacktrace.txt

Hi Friends! I’m facing an issue with SceneKit. I’m developing a 3D mobile game. I have a character 3D model and several skeletal animations CAAnimation. I import both the model and the animations from Maya in *.dae format. The character’s animations play continuously one after the other, with each new animation being triggered randomly. The transition between animations makes smoothly by setting the fadeInDuration and fadeOutDuration properties. Here’s an example of the code: import UIKit import QuartzCore import SceneKit class TestAnimationController: UIViewController { var bodyNode: SCNNode? override func viewDidLoad() { super.viewDidLoad() let scnView = SCNView(frame: self.view.bounds) scnView.backgroundColor = .black // Set your desired background color scnView.autoresizingMask = [.flexibleWidth, .flexibleHeight] let scene = SCNScene(named: "art.scnassets/scene/Base_room/ROOM5.scn")! bodyNode = collada2SCNNode(filepath: "art.scnassets/female/girl_body_races.dae")! bodyNode?.renderingOrder = 10 scene.rootNode.addChildNode(bodyNode!) playIdleAnimation() scnView.scene = scene // Assign the scene to the SCNView self.view.addSubview(scnView) // Add the SCNView to your main view) } func collada2SCNNode(filepath:String) -> SCNNode? { if let scene = SCNScene(named: filepath) { let node = scene.rootNode.childNodes[0] return node } else { return nil } } func playIdleAnimation() { let array = [ "art.scnassets/female/animations/idle/girl_idle_4.dae", "art.scnassets/female/animations/idle/girl_idle1.dae", "art.scnassets/female/animations/idle/girl_idle2.dae", "art.scnassets/female/animations/idle/Girl_idle3.dae", ] let animation = CAAnimation.animationWithSceneNamed(array.randomElement() ?? "")! self.setAnimationAdd( fadeInDuration: 1.0, fadeOutDuration: 1.0, keyTime: 0.99, animation, isLooped: false ) { [weak self] in guard let self = self else { return } try? self.playBoringAnimations() } } func playBoringAnimations() { let array = [ "art.scnassets/female/animations/boring/girl_boring1.dae", "art.scnassets/female/animations/boring/girl_boring2.dae", "art.scnassets/female/animations/boring/girl_boring3.dae", "art.scnassets/female/animations/boring/girl_boring4.dae", "art.scnassets/female/animations/boring/girl_boring5.dae", "art.scnassets/female/animations/boring/girl_boring6.dae", "art.scnassets/female/animations/boring/girl_boring8.dae" ] let animation = CAAnimation.animationWithSceneNamed(array.randomElement() ?? "")! self.setAnimationAdd( fadeInDuration: 1.0, fadeOutDuration: 1.0, keyTime: 0.99, animation, isLooped: false ) { [weak self] in guard let self = self else { return } try? self.playIdleAnimation() } } func setAnimationAdd(fadeInDuration : CGFloat, fadeOutDuration : CGFloat, keyTime : CGFloat, _ animation: CAAnimation, isLooped: Bool, completion: (() -> Void)?) { animation.fadeInDuration = fadeInDuration animation.fadeOutDuration = fadeOutDuration if !isLooped { animation.repeatCount = 1 } else { animation.repeatCount = Float.greatestFiniteMagnitude } animation.animationEvents = [ SCNAnimationEvent(keyTime: keyTime, block: { _, _, _ in completion?() }) ] bodyNode?.addAnimation(animation, forKey: "avatarAnimation") } } Everything worked perfectly until I updated to iOS 18. On a physical device, the animations now transition abruptly without the smooth blending that was present in earlier iOS versions. The switch between them is very noticeable, as if the fadeInDuration and fadeOutDuration parameters are being ignored. However, in the iOS 18 simulator, the animations still transition smoothly as before. Here two example videos - IOS 17.5 and IOS 18 https://youtube.com/shorts/jzoMRF4skAQ - IOS 17,5 smooth https://youtube.com/shorts/VJXrZzO9wl0 - IOS 18 not smooth I try this code in IOS 17.5, everything works fine Does anyone have any ideas on how to fix this issue?

I have been able to get rid of reported memory leaks in Instruments not by fixing a leak but by adding some lines (like releasing a previous nil object) that convinced Instruments it is not a leak. But I am stuck are some I cannot stop Instruments from reporting. It reports a leak in this code if(expr.length>0) { // add previous Atomic Atomic *atom = [[Atomic alloc] initWithString:[string substringWithRange:expr] isNumber:aNum]; [exprTokens addObject:atom]; [atom release]; } } and it underlines the substringWithRange method. I changed code to explicitly release atom and I assumed substringWithRange would return an autoreleased new string. I am aware Instruments tells you where the leaked object is created and not where it is leak, but only things created here are atom and a sub string and atom is released immediately. The initWithString method might do it, but I don't find anything there. Also, while running instruments, this code is 8542 times (I am pretty sure always in the same context) and Instruments says it only leaks 61 times. I don't now if there is misunderstanding are a code problem?

The "Debug View Hierarchy" feature of Xcode is very convenient to break down and debug a complex view hierarchy. But Metal content/layers/views do not render anything in this mode. Is there some special flag that needs to be set on the layer to support the Xcode feature? Or some special callback that needs to be implemented? I would naively assume that Xcode could do some kind of read-back from the window server or GPU, even for layers rendered via accelerated APIs like Metal or OpenGL, similar to what's done when recording/capturing the screen.

There have been occasional questions about remote debugging. Unfortunately I see a couple of them which were reasonable basic questions got no answer at all. I will try this again. A couple questions had some mention of lldb server. In some cases clearly the people asking the questions already knew a bit about remote debugging. Yet I can find no documentation about it.Does XCode or other tools that will work with XCode support debugging over the internet? If so what are the reqirements re XCode version and macOS version, whether the client and server can have unmatched versions, etc.?My immediate need (without extra steps) is to debug a process running on Sierra (no XCode installed yet) from a development system running XCode 7.3.1 under El Capitan.The need for remote debugging is to be able to diagnose crashes that don't happen on my development systems. There have also been questions concerning crash logs, but crash logs are of limited use unless the crash can be opened into a debugger with full ability to examine the stack and local variables.Thanks in advance!
