Delay in starting of Camera

[deepak013]

There is a delay in starting of Camera, sometimes its about 2-3 seconds and sometimes its up to 10 seconds. This is a bad user experience.

I am now using another library https://github.com/twostraws/CodeScanner
This library works perfectly, no delay in start of camera.

I don't see the slow launch on iPhone or iPad but I consistently see a 10 second delay when running my iOS app on an Apple Silicon Mac. I'm seeing more downloads of my app on macOS, so I'm interested in resolving this if at all possible. If anyone has any places to look, I'm open to suggestions. Everything I've checked so far with the start-up of AVCaptureDevice seems ok and I haven't found any causes of the delay using Instruments.
