After update to Xcode 13,
I encounter this problem
2021-11-02 17:07:57:380 : Undefined symbols for architecture arm64:
2021-11-02 17:07:57:381 : "___gcov_flush", referenced from:
2021-11-02 17:07:57:418 : ___34-[MyAppDelegate doCoverageWhenEnterBackground]_block_invoke in MyAppDelegate.o
2021-11-02 17:07:58:243 : ld: symbol(s) not found for architecture arm64
However it is normal when it is compiled by Xcode12.
I am pretty sure I follow the instructions in this article

Could anyone help me?
