Hey! I'm also also participating in the Swift Student Challenge and would like to use a third-party service. Whilst initially I added it as a package (using Swift Playgrounds), I've then looked into files and seen that the only reference that package has is a dependency link: dependencies: [ .package(url: "https://github.com/simibac/ConfettiSwiftUI", "1.0.1"..<"2.0.0") ], which seems that it indeed needs a network connection to resolve the package. What I ended up doing was including the source file from the GitHub repository (MIT Licensed) with credits and links. Best of luck on your app!
