I can flash the led-blink example only after removing this line ( /Users/roman/esp/esp-matter/connectedhomeip/connectedhomeip/config/esp32/components/chip; ) from build.ninja in build folder.
THIS IS TERMINAL OUTPUT AFTER TRYING TO BUILD smart-light example :

Please submit a bug report (Swift.org - Contributing) and include the crash backtrace.

The latest swift.org toolchain has this problem fixed.
The CI setup that Rauhul mentions is now in place, too, so that should show this build failure resolved.
I dont know if its related but i need to mention that i cannot successfuly build without deleting this line: /Users/romanbelka/esp/esp-matter/connectedhomeip/connectedhomeip/config/esp32/components/chip;
from any examples i try to build.
Error before deleting the line from build.ninja:

Can you share more details about your set up? Both the problems (needing to remove a line from build.ninja, and the linking problem) are pretty surprising to me. What OS are you on? Are you building in Docker? What CMake version do you have? What ESP IDF and ESP Matter versions do you have? Did you try a newer IDF?
OS: macOS Sonoma 14.6.1
Apple Swift version 6.2-dev (LLVM be8c96d78337932, Swift 0bbaa3519b62071) arm64-apple-macosx14.0
CMake version 3.31.2
ESP-IDF v5.2.1
ESP-Matter v1.3
No im not building in docker.
And im using same device as you in video(original ESP32-C6-DevKitC-1)
Executing "ninja flash"...
