I'm still learning Swift and Xcode, so I'm not sure what else is needed. If anything else is, please let me know, and I will edit this question.
The code I am running is the default playground code, where UIKit is imported, and a single variable is declared. I have tried uninstalling and reinstalling Xcode. I am also running the Monterey beta, so that may be causing the issue. My Xcode version is Xcode 12.5.1.
Any help is greatly appreciated!

Application crashes on simulator after update Monterey

I updated my mac Big Sur to Monterey Beta.
After update, my application (installed before) not opens on iPhone Simulator (crashes immediately). And on xcode lots of errors appears, can't build.
Simulator crash report:

Identical pending IRPs

I forced a complete kernel dump for an application that appears to be waiting on a deadlocked thread in a kernel driver. I believe I have identified the offending thread as it has 1920031 ticks (0:08:19:12.675) which is roughly how long the application has been waiting. The thread has also only spent .015 milliseconds in user and kernel time:

How can one thread have two nearly-identical pending IRPs to the same device and file?
How can the file object be open in two IRPs but only have one open handle?
Thanks!

The project compiled and works fine on Xcode 6.2 and prior, but when I try to compile it on Xcode 6.3 and 6.3.1, I got Command failed due to signal : Segmentation fault 11. Can someone help me? Thanks before.
EDIT : Just for your info, I currently use two Xcode in one Mac, Xcode 6.2 and 6.3.1, because Xcode 6.3.x can't compile my project so I'm still using Xcode 6.2, while trying to fix for 6.3.x.

Now Xcode is not getting launched?

Can an EXEC_BAD_INSTRUCTION (SIGILL) on dyld my fault?

I'm developing this app that worked beautifully on dev box and test box alike with osx 10.8.
Test box is significantly older hardware but same software setup as dev box.
Dev Box: intel core i7
Test Box: intel core 2 duo
Upon upgrade to OSX 10.9 Mavericks on both machines, I'm getting an EXEC_BAD_INSTRUCTION(SIGILL) failure on my test box with an error report that seems to suggest a problem with 10.9.
Is it possible that it's something I did or should I nag Apple to fix their Os?
I have tried all the DYLD_PRINT_* env variables to see if I get some clues, but it just fails with no abnormal or indicative messages.
Any Ideas as to what It could be or where to look further/deeper?
Your interpretation of this trace is also welcome.

So I found the problem.
My libraries were built using homebrew. By default homebrew optimizes for native architecture, resulting in machine instructions that don't work on older machines.
to prevent brew from building processsor-speciffic optimisations you must
brew install --build-bottle protobuf ( or your specific lib )
