During October 2025, work centered on enhancing caching strategies within the xmtp/xmtp-ios repository by implementing a targeted Client Cache Key Enhancement. This update improved cache correctness and gateway routing reliability by incorporating the gatewayHost into cache key generation. The approach involved updating ClientOptions to carry the gatewayHost and extending the ApiCacheKey string representation to include this new parameter, ensuring more robust cross-gateway caching. The work leveraged Swift and focused on client-server communication and iOS development practices. This feature laid the groundwork for future improvements in caching architecture, addressing the need for more precise and reliable cache management across gateways.
