 Contains information about the compiled artifacts of a Swift module.
 
-This provider has a custom initializer that will merge the transitive modules of
-a list of `SwiftInfo` providers, rather than a separate "merge" function. The
-correct signature when _creating_ a new `SwiftInfo` provider is the following:
-
-```build
-SwiftInfo(
-    direct_swift_infos,
-    modules,
-    swift_infos,
-)
-```
-
-where the arguments are:
-
-*   `direct_swift_infos`: A list of `SwiftInfo` providers from dependencies
-    whose direct modules should be treated as direct modules in the resulting
-    provider, in addition to their transitive modules being merged.
-*   `modules`: A list of values (as returned by `create_swift_module_context`)
-    that represent Clang and/or Swift module artifacts that are direct outputs
-    of the target being built.
-*   `swift_infos`: A list of `SwiftInfo` providers from dependencies whose
-    transitive modules should be merged into the resulting provider.
-
-When reading an existing `SwiftInfo` provider, it has the two fields described
-below.
