Build error when adding to project

[jayKayEss]

Hi! Using SwiftPM, this package fails immediately after adding to a project with the following error:

Conflicting options '-warnings-as-errors' and '-suppress-warnings'

This seem to be caused by this in your package manifest:

.treatAllWarnings(as: .error),

The build failure doesn't affect your CI because Xcode is forcing the -suppress-warnings flag on build. IDK if that can be changed.

error: Conflicting options '-warnings-as-errors' and '-suppress-warnings' (in target 'AsyncQueue' from project 'swift-async-queue')

@jayKayEss I take it -suppress-warnings coming from your project? We don't have that anywhere in this repo. Can you help me understand how you've configured your project to suppress warnings in 3rd party SDKs?

In the interim you can likely work around this by utilizing 0.7.2 which doesn't have this flag.

Okay so I can reproduce this in a project that also has all warnings as errors turned on. Nuts. Looking into it.

Well seems like this is out of my control, so I'm just going to remove .treatAllWarnings(as: .error), and create a new release. Thanks for letting me know!

Fixed in 1.0.1
