Supabase's Swift SDK quietly fixed a data-corruption bug in typed upserts while the CLI shored up its testing infrastructure, and realtime rolled through five new versions overnight.

The supabase-swift team landed a critical fix for typed upserts: a missing conflict target meant calls on keyless relations silently inserted duplicate rows, and the raw String `onConflict` could surface typos as runtime 400s [1]. They also closed the gap that prevented typed updates from setting nullable columns to NULL, forcing callers to drop to the legacy string builder [2]. These come alongside a refactor that rebuilds HTTPRuntime on swift-http-types, aligning the SDK's HTTP layer with the ecosystem [3]. Meanwhile, supabase/cli shipped v2.116.0 with fixes for piped stdin buffering, loopback proxying, and more [4], and the team sharded package-local test suites to speed up CI [5]. The supabase/postgres repo tagged five new amcheck releases across versions 15 and 17 [6][7][8], while slim-services rolled out realtime v2.130.0 and postgres 17.6.1.166 as portable artifacts [9][10].
