Tuple (`[A, B, C]`) doesn't work in Swift

When creating a tuple, the Swift code gets generated but it won't compile.

Tuple:

interface MyHybrid extends HybridObject<{ ios: 'swift' }> {
  someFunc(value: [number, number, number])
}

Generated Swift:

class MyHybrid implements MyHybridSpec {
  func someFunc(value: (Double, Double, Double)) {
    // do nothing
  }
}

Looks good, but unfortunately it will fail to compile because the Swift compiler inserted an additional < and > around the C++ type (std::tuple<<...>> instead of std::tuple<..>) in the generated -Swift.h header:

- SWIFT_INLINE_THUNK std::__1::tuple<<double, double, std::string>> MyHybridSpecCxx::getSomeTuple() {

I already reported this bug in the Swift compiler repo: https://github.com/swiftlang/swift/issues/75865

Until that's fixed, tuples are currently not supported in Nitrogen.

Start by reproducing the tuple case from the issue and inspecting the generated -Swift.h declaration. Read the linked Swift compiler issue #75865 to determine whether a project-side path remains available. Done means tuple support no longer produces the malformed nested std::tuple angle brackets and the generated Swift interface compiles.
