Build Error for iPhone app

Hi.
I’m currently making jump game for iPhone using Unity 2d.
I’m using Unity version 2019.1.5f and Xcode 10.2.1.

The error message is

Undefined symbols for architecture arm64:
  "_StaticBurstStaticMethodLookup", referenced from:
      _BurstStaticMethodLookup in lib_burst_generated.o
  "_Staticburst_initialize", referenced from:
      _burst_initialize in lib_burst_generated.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

All help welcome!
Thanks.

I found answer for myself.
In my case, the errors were caused by not-up-to-date 2D animation package.
After update to latest version, unity and xcode build my test version successfully.
