## Summary Add missing `import NitroModules` to `HybridViewModelInstance.swift`. This import is required for `RuntimeError` which is used in the `replaceViewModel` method added in #96. ## Note on CI The iOS build in #96 passed because CI may have cached the build or the error only surfaces in clean builds. This fix resolves the build error.
