I would also like to know this. I have a package that needs to expose some configuration for the app but with strict concurrency it's impossible without tying all functions to @MainActor which isn't practical. Is there a way to set a non-isolated global variable once at init which can then be accessed through the life of the application? Or a setting that can be set at compile time? I think SwiftSettings would be best but I hate to have a boolean for each state rather than set a variable to an enum value once.
