Can package use @available to manage functionality while maintaining backwards compatibility?

[SDGGiesbrecht (Jeremy David Giesbrecht)]

Is is probably this:

Package, SwiftUI, ≤ iOS 10

Has anyone found a workaround to use SwiftUI guarded with @available in a package that has a deployment target ≤ iOS 10? (The default is iOS 8.) @available works fine for the other platforms, and works if the deployment target is > iOS 10, but with ≤ iOS 10, you get “Use of undeclared type” errors.

Archiving probably builds for all architectures, whereas your other builds may only involve the particular architecture of the current device.
