Mac OS X: Camera Authentication from QT Creator very slow!

ademmler

Hi folks.

As you may know you need to set NSCameraUsageDescription string in Info.plist file
to allow camera access on Mac OS X. This works nice and perfect if you double click the final application.

While coding in QT creator and running the app from there the start is very slow.
From finder its take 1-3 seconds - from QT Creator it needs 40 seconds.

Does anyone knows a trick how to solve this?

From apple documentation for reference:

And The Qt version you are using in your Kit is also 5.14.2 ?

By the way, do you have a minimal compilable examine that shows that behaviour ?
