web:rollup executor doesn't produce declarations with compiler set to swc

Current Behavior

When running nx build for my buildable library I don’t get d.ts files in the output directory.

Expected Behavior

d.ts files should be generated.

Steps to Reproduce

1. Generate a buildable library with --compiler swc
2. Build it

Still relevant.

I’m having the same issue too. And from what I can see in the swc thread

https://github.com/swc-project/swc/issues/657

It seems like a missing feature so I thought the missed types in NX are expected.

Not a big issue for compiling and bundling apps, but for libs that mean to be published to NPM, this is an essential feature.
