@Larme what link you have provided is not related to this crash . I also gone through this link . But it didn't fix my issue . — Abhishek B, Sep 13 '19 at 11:00
What's your code? Only in iPhone X? And in iOS12 it works? In an iPhone 8? iPhone XS? iPad? Could it be limited to the video camera? Cf. logic there https://stackoverflow.com/questions/53213054/crash-when-using-front-camera-only-on-pre-iphone-7-devices/53214766#53214766 — Larme, Sep 13 '19 at 11:02

If u are trying to run a camera session by configuring AVCaptureSession in your application it automatically adjusts AVCaptureDevice's activeFormat and activeColorSpace properties based on the supportedColorSpaces of the device's formats and the current AVCaptureSession topology. Try setting the property "automaticallyConfiguresCaptureDeviceForWideColor" of class AVCaptureSession to false.

captureSessionInstance.automaticallyConfiguresCaptureDeviceForWideColor = false

Also stop the running capture session when your not in that view and restart again when needed.

captureSessionInstance.stopRunning()

captureSessionInstance.startRunning()

Thanks @syed with captureSessionInstance.automaticallyConfiguresCaptureDeviceForWideColor = false its working fine . — Abhishek B, Sep 16 '19 at 05:35

The error message says:

-[AVCaptureDevice setActiveColorSpace:] Not supported - use activeFormat.supportedColorSpaces'

You are trying to pass a value that is not available. According to the apple docs not all devices have the same list of available color spaces. https://developer.apple.com/documentation/avfoundation/avcapturedevice/1648668-activecolorspace

This is why it only fails on XR as you mentioned.

You need to check what values are supported on the current device using activeFormat.supportedColorSpaces before you try to set it.
