[JExtract/FFM] Translate 'some DataProtocol' parameters to 'Data'#303
Merged
Conversation
* Introduce `SwiftType.opaque(SwiftType)` and `.existential(SwiftType)` to represent `some` and `any` types respectively. * Introduce `SwiftKnownTypes.representativeType(of:)` to the hardcoded `DataProtocol` -> `Data` translation mapping.

@ktoso I'd be happy to make this and Data thing test cases, but where exactly I should write? Any PR testing runs Samples:SwiftKitSampleApp:test?

So every example has a ci-validate.sh and you can add a ./gradle test in there in Samples/SwiftKitSampleApp/ci-validate.sh and add a test in Samples/SwiftKitSampleApp/src/test/java/com/example/swift :)

Also, run Samples:SwiftKitSampleApp:test in CI
