Subject: [PATCH] test(ios): use_modular_headers! for legacy pods after
 dropping useFrameworks

Without useFrameworks:static, old Obj-C pods (react-native-udp -> <React/RCTAssert.h>) lose the React umbrella header. use_modular_headers! restores module header maps so <React/...> resolves for udp and any other legacy pod, in one shot. SwiftUICore already gone (build #5). udp is abandoned (4.1.7, 2023) with no drop-in replacement, so patching headers beats replacing it. [unsigned: GPG]
