Since React Native 0.75, the spm\_dependency helper lets libraries declare SPM packages directly in their podspec files, enabling support for third-party Swift packages distributed only through SPM. This article explains how the integration works, how to adopt it for both remote and local packages, and what to expect until official support ships.
