iOS Question LL Camera Example Crash [SOLVED]

[JohnC]

I'm running iOS 11.4.1 and I downloaded the LL Camera Example from here:

LLCamera - Low level camera access

iMedia library v1.10 includes a new type of object named LLCamera. LLCamera provides low level camera access, similar to B4A Camera library. If you just want to allow the user to take a picture then it will probably be better to use Camera instead of LLCamera. LLCamera allows you to embed the...

I simply unzipped the example and tried to run it as-is.

The background of the app quickly appears black, then the app crashes with this log:

Any ideas whats going wrong?

Might it be with camera permission because I would have expected a pop-up asking if the app can use the camera (in order to show the preview), but nothing popped up.

Well, my hunch was correct - I needed to add this line in the Project Attributes of the example to allow for the permission:

#PlistExtra:<key>NSCameraUsageDescription</key><string>Taking a photo and attach to the task.</string>

(should the posted example be updated to have this line in it?)
