Why don’t you open AVCaptureDeviceTypeBuiltInTripleCamera or AVCaptureDeviceTypeBuiltInDualWideCamera, and switch between the wide and ultra-wide lenses by adjusting the zoom?

“Why do you need the step of converting linear to sRGB? Try this library: https://github.com/BradLarson/GPUImage3 — it should follow the same workflow, outputting YUV and then previewing with Metal.”

We are experiencing the same issue on our side. Recently, we’ve seen a noticeable increase in user reports where the camera goes black, and the logs show AVCaptureSessionInterruptionReason.videoDeviceNotAvailableWithMultipleForegroundApps. This started happening much more frequently after iOS 18.5. We’ve already submitted feedback to Apple about this over a week ago, but unfortunately haven’t received any response yet. Has anyone found any effective workaround or has any insight on whether there were camera-related changes in iOS 18.5? Would appreciate any suggestions or shared experiences on how to handle or avoid this issue.

And users have reported that when the above error occurs and causes the camera to go black, restarting the app does not resolve the issue. Other camera-related apps also show a black screen. The only way to fix it is by restarting the phone.
