There was a problem hiding this comment.
Since ContextModel is part of PackageLoading and PackageDescription via a symlink, we need to import Foundation implementation-only in both modules. This is incompatible with IdentityResolver since it uses Foundation.URL as part of its public interface. To resolve this, I moved IdentityResolver into PackageModel here.

…sions This changes all imports of `Foundation` in the `PackageDescription` module to be implementation-only, making it so that it needs to be explicitly imported if being used. To avoid breaking existing packages, we inject an explicit import into manifests with tools-version 5.7 or earlier. In the next tools-version, `Foundation` will no longer be implicitly available. rdar://92879696

Reverts 1998284 / swiftlang#3526 Related to SR-14718 (swiftlang#4416). Since swiftlang#3526 was merged, swiftlang#5874 tried to apply the original idea of using `@_implementationOnly Foundation` in PackageDescription/Plugin to avoid leaking `Foundation` into the manifests.
