SDK 56 makes JavaScript to native calls significantly faster on iOS by letting Swift talk to JSI directly. We eliminated the Objective-C++ layer and saw 1.6-2.3x performance improvements across our benchmarks. Before this change, every native module call went through three languages. Now it's just Swift making a direct C++ call. Here's how we did it and what the performance gains look like. The three-language problem Prior to SDK 56, calling an Expo native module from JavaScript meant crossing m
