Same here, but when trying to implement Apollo for Graphql as a swift package

how to resolve?

[hengkx]

I use the following method to solve the problem

LIBRARY_SEARCH_PATHS = (
   "\"$(TOOLCHAIN_DIR)/usr/lib/swift/$(PLATFORM_NAME)\"",
-  "\"$(TOOLCHAIN_DIR)/usr/lib/swift-5.0/$(PLATFORM_NAME)\"",
+  "\"$(TOOLCHAIN_DIR)/usr/lib/swift-5.2/$(PLATFORM_NAME)\"",
   "\"$(inherited)\"",
 );

@hengkx cool, now it builds 😃

I also had this issue and asked about it on the Swift forums. The cause is trying to link against an older Swift runtime while targeting a newer version of the OS.

You should be able to just remove those LIBRARY_SEARCH_PATH entries entirely (or just leave $(inherited)) and that will fix the problem. This is a bug in the ReactNative template for iOS.

As mentioned in the above Swift forums thread:

You shouldn't need to add the toolchain library paths to LIBRARY_SEARCH_PATHS yourself, because Xcode will automatically include those libraries if your minimum deployment target is old enough to need them.

@hengkx, it works for me! Thanks a lot!

Sorry for commenting on a closed issue, but I'm still experiencing this problem and nothing seems to help. I've tried changing my IPHONEOS_DEPLOYMENT_TARGET to 9.0, 10.0, 11.0 and 13.5, nothing works. I've tried @hengkx 's fix, didn't work. I've tried leaving only inherited in there, and removing it entirely, still didn't work. Can anyone help me out here?

EDIT: Fixed it! My notification service extension had a different deployment target version than the RN app.

Same issue here, adding a WidgetExtension to a blank react-native app causes this issue. None of the above fixes seem to work

👆 This is the real fix

@mcoevert true. I just remove those LIBRARY_SEARCH_PATH entries completely, it'll fix the problem
