Code is download from apple official metal4 sample
[https://developer.apple.com/documentation/metal/drawing-a-triangle-with-metal-4?language=objc]
enable metal gpu trace in macOS schema and trace a frame in Xcode.
Xcode may show segment fault on App from some 'GTTrace' function when click trace button.
When replay a .gputrace file, Xcode may crash , throw an internal error or a XPC error.
The example code using old metal-renderer can trace without any problem and everything works fine.
Test Environment:
Xcode Version 26.2 (17C52)

I notice some metal-cpp classes have static funtion like
static URL* fileURLWithPath(const class String* pPath);
static class ComputePassDescriptor* computePassDescriptor();
static class AccelerationStructurePassDescriptor* accelerationStructurePassDescriptor();
which return a new object.
these classes also provide 'alloc' and 'init' function to create object by default.
for object created by 'alloc' and 'init', I use something like NS::Shaderd_Ptr or call release directly to free memory. Because 'alloc' and 'init' not explicit call on these static function.
I wonder how to correctly free object created by these static function? did they managed by autorelease pool?
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSBundle allFrameworks]: unrecognized selector sent to instance
NS::Bundle* Bundle = NS::Bundle::mainBundle(); Bundle->allFrameworks();
call to allFrameworks() and allBundles() will throw exception, but other functions work well.
