For me, I was building on the Apple M2 chip. After several hours of attempts, I found that I could successfully build on a real device, but the build failed on the simulator. When I commented out the following code, the build also succeeded on the simulator.

# Comment this line due to a build failure on Apple M2 Pro with an error: "VisionCamera.modulemap not found."
# config.build_settings['EXCLUDED_ARCHS[sdk=iphonesimulator*]'] = "arm64"

close Xcode
