Warning about main queue setup

[brascene]

First of all thanks for the lib, I found it very useful and easy to use, just one small issue with this warning, is this something that can be ignored or something that needs to be fixed?

Thanks for the kind words. I haven't updated this lib in some time, but hopefully will get to it one day soon.

This is a warning so it likely can be safely ignored. However, it really should be fixed.

Happy to accept a PR that fixes this if you're up to the task. :)
