Load package resources from within the same package

I'm building a Swift Package that contains a text resource inside /<project_name>/Sources/<target_name>/Resources/names.txt. The resource is being copied into the target as:

resources: [

... and the Bundle.module accessor is generated (the Bundle.module call is performed from within the Swift Package). Still, when testing the code in a Playground, by calling the function that calls the function that calls the Bundle.module.path ... (so not directly from the Playground), it mentions:

SPK/resource_bundle_accessor.swift:27: Fatal error: unable to find bundle named swift-spk_SPK

I'm following the guidelines I found on tutorials and within a similar question from last year here: Finding Swift Package Manager Resources so I'm curious if there have been any changes to the resource loading.
