"Call can throw, but it is not marked with 'try' and the error is not handled" when trying to access ultrawide camera on iPad Pro

[nikhilrama]

I am attempting to access the iPad Pro's ultra-wide angle camera with ARCamera. I have made the following modifications to the original files and am getting an error when trying to build.

NextLevel.swift: added ultrawideangle camera case to enum list and AVCaptureDevice.DeviceType

NextLevel+AVFoundation.swift: Modified the primaryVideoDevice method as instructed here: #187

ViewController.swift: added this line: nextLevel.changeCaptureDeviceIfAvailable(captureDevice: .ultraWideAngleCamera) to the video configuration area within the setupCamera() function. This is where I am getting the error. Any advice on how to resolve + actually access the ultrawide cam would be appreciated.

Simply add try (or try? or try!, depending on your use case) in front of the method invocation
