Generally I can do as following steps to experiment a swift package in a macOS Playground:
- clone the project
- use 'swift package generate-xcodeproj' to generate a Xcode project
- go to "File -> Save As Workspace..." generate a Xcode workspace
- add a macOS Playground into the workspace
- in the Playground import the package and start to experiment it
But when I try to experiment swift-nio, I got "error: missing required module 'CNIOAtomics' "
how can I fix this?
