First of, excellent and easy build instructions! Thank you!

I'm running into an error however.

Okey, the cam is lighting up now, however the error message still shows every time on start up:

And Chrome tells me that there isn't any Camera found.

It mentioned macOS 10.15, but I'm still on Mojave, 10.14.6 (18G103). I'll see if I can simply set the target to 10.14.

Simply setting it to 10.14 did indeed work:

Good find, feel free to update the README since this just seems to be an Xcode “feature”
