Summary

Based on the results of the latest build results at the Swift Package Index, the SPM package cannot compile for Swift v5.

Explanation

From what the logs are telling, the declaration of a specific error thrown at a function is not supported by the mentioned version of the Swift compiler. These definitions are being used on the functions defined at the AmiiboService service type and at the APIClient protocol as well, like this:

func someFunctions() async throws(AmiiboServiceError)

Posible solution

Both the AmiiboService service type and the APIClient protocol should have two functions definitions, one for Swift 5 and another for Swift 6. The same goes for the types that conforms to this particular protocol. It is assumed that a syntax like this will be used to solve this issue:

#if swift(>=6.0)
    // …
#else 
    // …
#endif
