I have the exact same issue. Tried looking everywhere online for a fix or a workaround, but haven't found anything that works yet. Really disappointing.

Just putting in an update here for anyone who stumbles upon this post and has a similar issue. This is resolved by adding this entry into your Package.swift file: .testTarget( name: "PackageNameTests", dependencies: ["PackageName"], resources: [ .copy("Resources/test.png") ] ) After that's all synced, you can use the below code to access the correct path to access the resource: Bundle.module.path(forResource: "test", ofType: "png")
