Unity Xcode build Error Undefined symbols AppsFlyerAdRevenueWrapper

Hello, I'm integrating AppsFlyer SDK to my Unity Game. When I build with Xcode 14 and 15 in MacOS 13.6, I got this error:

Undefined symbols for architecture arm64:
  "stringFromChar(char const*)", referenced from:
      __logAdRevenue in AppsFlyerAdRevenueWrapper.o
  "dictionaryFromJson(char const*)", referenced from:
      __logAdRevenue in AppsFlyerAdRevenueWrapper.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Any help figuring this out would be greatly appreciated!
