问题
I am trying to run OpenCV projects in Xcode and it seems like there's a new need to provide an info.plist for C++ applications NSCameraUsageDescription.
2018-09-28 00:03:15.181948+0800 k_nearest_detector_v2[23505:710470] [access] This app has crashed because it attempted to access privacy-sensitive data without a usage description. The app's Info.plist must contain an NSCameraUsageDescription key with a string value explaining to the user how the app uses this data.
Program ended with exit code: 9
How do I go about creating a .plist file for a C++ project as it has never been needed before.
回答1:
Found a solution. Put the file with the desired NSCameraUsageDescription, NSMicrophoneUsageDescription (or others) with the assembled file from XCode (See screen shots below). For the Release and Debug versions.

You can even automate the steps described by @Valery Gromov. Just copy the file in the Build Phases. Uncheck the Copy only when installing checkbox to be able to run it directly from Xcode.
