Hi 897132128,

Thanks for the post. The log message you are mentioning is a normal console output, which is not the reason why you are facing this issue. Currently our Mac SDK does not support Xcode 11. Can you have a try with Xcode 9 and see if the issue still exists?

Thanks!

I have used xcode9.4.1, but this error still occurs.47
