I have command line tools installed:

Thus clang is installed here:

However, I still cannot compile any c++ code, even the simplest one:
#include <iostream>
using namespace std;
int main() {
cout << "Hello World!" << endl;

}
It returned this error:

It seems to be command line tools related. But I've already installed the most recent version of CLT and gcc.
Additionally, clang can compile the same code:

Hello World!
What else shall I do to make this g++ compiler work?

I observed the following problem:
A scientific code to perform Reverse Monte Carlo simulations (‘rmcxas’) compiled with the most up to date version of gcc/gfortran and Xcode including command line tools on Mac OS Sequoia 15.4 on a Macbook air with M4 processor generates the following problem upon starting it in a terminal:
dyld[10154]: dyld cache '(null)' not loaded: syscall to map cache into shared region failed
dyld[10154]: Library not loaded: /usr/lib/libSystem.B.dylib
Referenced from: <0144F82E-003C-37A9-A544-9AE6336E549B> /Users/markuswinterer/bin/rmcxas
Reason: tried: '/usr/lib/libSystem.B.dylib' (no such file), '/System/Volumes/Preboot/Cryptexes/OS/usr/lib/libSystem.B.dylib' (no such file), '/usr/lib/libSystem.B.dylib' (no such file, no dyld cache), '/usr/local/lib/libSystem.B.dylib' (no such file)
zsh: abort rmcxas
This occurs only about every 5th time the code is started.
Help would be highly appreciated.
Hi guys!
I have gone through an absolute nightmare, trying to solve the issue that I am about to tell you about.
As the title says, I am getting the error:
Library '/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/17/lib/darwin/libclang_rt.profile_driverkit.a' not found
I trimmed off part of that directory as I did not want to reveal that information about my computer.
From what I can tell, the file in question is no longer even a part of Xcode. I have searched, it is not on my computer anywhere.
I have also downloaded older versions of Xcode to search with it. None of them have it.
I have literally tried everything under the Son to solve this issue.
I have been stuck on it for two days.
I have even resorted to doing something I hate, which is asking for ChatGPT to assist me with solving the issue. No help there.
I am at my wits end. So I am coming to you guys, have you seen this error?
Any ideas at all? The odds are pretty good whatever you recommend I have probably already tried 200 times over. But I am still open to hearing anything.
Have any of you had this error? Any ideas?
I am on the latest version of macOS.
The project is for a macOS app.
M4 Mac mini.
Any additional information I can provide, that will be helpful?
At this point, I am leaning more towards this being a bug with Xcode than anything.
Hello,
I'm developing a macOS application that uses the Virtualization framework to run Linux virtual machines (specifically Ubuntu and Fedora) on Apple Silicon Macs.
I've noticed that while the macOS host properly supports all trackpad gestures, the two-finger tap gesture for right-click does not work within the Linux guest. Only the primary click is recognized. This behavior is consistent across different Linux distributions and desktop environments (GNOME, KDE, etc.).
I would like to confirm:
Is the macOS Virtualization framework expected to support trackpad gestures such as two-finger tap for right-click within Linux guest VMs?
If not currently supported, is there a known workaround to enable right-click functionality for the trackpad in Linux guests? (e.g., configuration changes in the VM, Linux kernel input modules, or framework-level adjustments.)
Any insights or suggestions would be greatly appreciated.
Thank you!
Is this a valid thing to include in the Info.plist file?
If so is a category of public.app-category.astronomyvalid? I couldn't find that, but the categories I did find seemed very limited.
I'm developing for compliance with Texas law in the United States.
Currently, I'm encountering an issue where I want to test the feature point "when the app undergoes significant changes, a supervised user initiates a request." However, during actual testing, the app pops up an error message: "Can't Ask, An Unknown error occurred."
Additionally, I see the following error message in the Xcode Console: "Error Domain=AskToCore.ATMessageComposeValidationError Code=4 'The user is in a region that does not support this type of ask.' UserInfo={NSLocalizedFailureReason=The user must be in a supported region to use this feature., NSLocalizedRecoverySuggestion=Please ensure the user is in an eligible region., NSLocalizedDescription=The user is in a region that does not support this type of ask.}"
I am indeed not in the Texas region.
I want to conduct full-process testing before the feature is released to the App Store.
What should I do?
Apart from Sandbox testing (which, in fact, doesn't show any pop-ups either), how can I test under real-world conditions?
We are trying to setup Apple Unity Plugins, in out project we have a handful of developers who contribute to the project via git.
When building and importing plugins via tarball (as instructed in the Github repo) the package clearly points to local path, so once pushed all members encounter the error:
An error occurred while resolving packages:
Project has invalid dependencies:
com.apple.unityplugin.accessibility: Tarball package [com.apple.unityplugin.accessibility] cannot be found at path .....
When trying to actually move content to the package folder (same way as any other unity plugins is setup) and add it as "embedded", it works fine on local machine, but team members will get a few of errors:
[Apple Unity Plug-ins] No Apple native plug-in libraries found.
DLLNotFoundException: AppleCoreNativeMac assembly ...
No Apple Native plug-in libraries found.
Moreover AppleCoreNativeMac.bundle is flag as not verified and deleted by macOS.
What is the right way to setup unity plugins in a project used by multiple members via sourcetree ?
I am building an iOS app with the App ID: com.echo.eyes.app
I have a paid Apple Developer membership and have followed all correct procedures, including:
Adding com.apple.developer.speech-recognition manually to the App.entitlements file
Setting Info.plist keys for microphone and speech permissions
Assigning my Apple Developer Team to the project
Setting App/App.entitlements under Code Signing Entitlements
Despite all this, Xcode automatic signing fails, and I receive the error:
vbnet
Copy
Edit
Provisioning profile 'iOS Team Provisioning Profile: com.echo.eyes.app' doesn't include the com.apple.developer.speech-recognition entitlement.
I am unable to add the entitlement via the Capabilities section, and no method I try will allow provisioning to succeed.
Please update this App ID to include the required entitlement in the provisioning profile. This issue is preventing all voice recognition functionality.
Thank you.
Hello,
I’m trying to test a Xamarin.iOS application using the iOS 26 simulators in Mac Visual Studio, but I’m encountering an issue where the simulators are not appearing or accessible from Visual Studio.
Details:
macOS version: 15.6 (24G84)
Xcode version: 26 Beta 5
Visual Studio version: 17.6.0.80
Xamarin.iOS version: Xamarin.Forms (Version: 4.6.0.1180) using XAML for cross-platform support (iOS/Android)
The problem started after updating to iOS 26 SDK. I am unable to select or run the app on any iOS 26 simulator from Visual Studio.
Has anyone faced a similar issue? Is there any configuration or workaround to enable iOS 26 simulators for Xamarin projects?
Thanks in advance for your help.

I can see that a MacOS VM guest running on top of an Apple Silicon MacOS host has GPU acceleration - indicating GPU sharing capabilities for the hardware.
Is there also a way to have GPU acceleration in Linux guests (with Vulkan/Mesa drivers)?
I'm running macOS 15.5. I now have Xcode 26 and I'm testing my iOS app against iOS 26. I've encountered several UIKit / iOS 26 bugs I'd like to report. In Feedback Assistant I choose "Developer Technologies & SDKs". Eventually I get asked "What build does the issue occur on?". The list of choices is:
iOS 18.2 Seed 4
iOS 18.1.1
iOS 17.7.2
An earlier iOS build
I'm not sure
So how to I report this as an iOS 26 beta 1 issue?
Hi everyone,
I'm developing a visionOS application using Unity with an enterprise developer account. I applied for the Main Camera Access entitlement, but at the time of submission, the email address associated with my Apple ID was deactivated, so I couldn’t receive any email communication from Apple.
Later, I updated the email address for my Apple ID. Now, in the Apple Developer portal under Identifiers, I can see that my app has been granted Main Camera Access, and I can also add the corresponding capability in Xcode.
However, according to Apple’s documentation(https://developer.apple.com/documentation/visionos/building-spatial-experiences-for-business-apps-with-enterprise-apis):
“To use entitlements, you need to include both the entitlement file and a corresponding license file in your app. After Apple approves your app for one or more entitlements, you receive a license file, along with additional instructions.”
I never received this license file, possibly due to the deactivated email. I don't know where to find it or how to retrieve it now.
What exactly is this license file?
If it was originally sent to an unreachable email, how can I request it again or get it resent?
Where in the Apple Developer portal (or elsewhere) can I access or download this file?
Any help or guidance would be greatly appreciated!
Thanks in advance.

Hi! I was wondering if anyone else encountered similar issues and what the solution ended up being.
We're encountering weird sign-in issues on our iOS version of our app. It seems like an uninstall and reinstall solves it, but the issue seems to only impact users who underwent the transfer process from one iOS device to another. What I am curious about:
What is copied over from one device to another in this process?
Is there a way outside of owning multiple test devices to replicate this flow?
Our current suspicion is that NSUserDefaults is not being cleared by our app on first start, and that stale data is copied over during this transfer process, breaking the sign-in until a re-install wipes everything properly.
Does it seem like we're on the right track with this assumption, or completely out to lunch?
What happen when a deprecated method is used in project submitted to Apple Store Connect ?
Generally the Apple documentation give the alternative like "Use ***: instead" but sometime the documentation do not suggest anything.
What to do when a such Warning happen ?
This is from an Xcode generated file.
var values: [String] = []
let exp = Expectation()
let c = pub.filter { $0 != nil }.map { $0! }.sink(
The second line gives an error: "'Expectation' cannot be constructed because it has no accessible initializers". My best guess that Expectation objects come from some other Apple Swift Testing function, but I don't know where.
Hi, I am having an issue with xcodebuild -showdestinations command.
Steps to reproduce:
Create a new iOS application project in Xcode or use an existing one.
Navigate to this project in a terminal.
Run xcodebuild -project 'your-project-name.xcodeproj' -scheme 'your-scheme' -showdestinations
What I expect:
All destinations available in the Xcode UI should be listed.
What I get:
It depends. For new projects, I consistently get only generic platform destinations and my connected physical device.
When I run the same command on an older project, I sometimes see all the expected destinations. It seems to be a roughly 50/50 chance between the two outcomes.
Is there a way to get consistent results from xcodebuild -showdestinations? What can I do to ensure all destinations are listed reliably?
Here is a more detailed log and a screenshot:

Hello, I need a little bit of help. My game keeps crashing on launch no matter what I do. I’ve tried running it in Xcode on my Mac, on my iPhone, and through TestFlight, but I get the same result every time.
I’ve tried everything I could find on the internet, and nothing worked. Asking here is my last resort because I’m completely stuck.
The game runs fine in Unity, but not so much in Xcode.
Can someone help me figure out what I’m doing wrong?Any help would be greatly appreciated.
Here is the error log I found by connecting my iPhone to my Mac. To view the logs, I used the Console in the Devices and Simulators section of Xcode.

I can see that iOS beta 2 was released yesterday. I'm not running the beta yet on my actual iPhone, but I wanted to see if an issue I reported in beta 1 was fixed.
Is there a way to update my iOS 26 simulator for beta 2? Usually, there's a new Xcode download that includes the new simulator, but it looks like the most recent Xcode beta release was June 9.
