Is anyone have this problem on xcode 26 ? Undefined symbol: _swift_FORCE_LOAD$_swiftCompatibility50 Undefined symbol: _swift_FORCE_LOAD$_swiftCompatibility51 Undefined symbol: _swift_FORCE_LOAD$_swiftCompatibility56 Undefined symbol: _swift_FORCE_LOAD$_swiftCompatibilityConcurrency Undefined symbol: _swift_FORCE_LOAD$_swiftCompatibilityDynamicReplacements
Historically I’ve seen errors like this when different parts of your Mach-O image — so object (.o
) files or static libraries (.a
) — are build with different tools or different deployment targets. Make sure that:
- You’ve rebuilt everything with Xcode 26.
- Your deployment targets are consistent.
Share and Enjoy
