SWC Plugin Compatibility

If you see errors like these during your build:

failed to invoke plugin on 'Some("/app/src/file.ts")'
failed to run Wasm plugin transform
RuntimeError: out of bounds memory access
LayoutError called Result::unwrap()

This is NOT a bug. You're using an incompatible version of @lingui/swc-plugin with your SWC runtime.

Why This Happens

SWC plugin support is experimental. The plugin API does not follow semantic versioning.

SWC uses Rkyv to transfer the AST between the core and plugins. Both must agree on the exact memory layout of the AST. If the layout changes (e.g., new ECMAScript features), older plugins cannot read the data correctly.
