My xcode updated to version 12 and since then I’m getting build error:

output:
Undefined symbols for architecture x86_64:
  "_objc_setHook_setAssociatedObject", referenced from:
      _platform_objc_objc_setHook_setAssociatedObject_wrapper100 in libobjc-cache.a(result.o)
     (maybe you meant: _platform_objc_objc_setHook_setAssociatedObject_wrapper100, knifunptr_platform_objc100_objc_setHook_setAssociatedObject )
ld: symbol(s) not found for architecture x86_64

Any idea how to fix this? 😓

Does adding kotlin.native.cacheKind=none to gradle.properties help?

[zalewski.se]

Yeah, it fixes the problem but I wonder if there is anyway without disabling the cache. 💭 Btw. Kotlin ver is still 1.3.72

[sergey.bogolepov]

Unfortunately, no.

[sergey.bogolepov]

Actually, you could try updating to 1.4.10. We improved dead code elimination for caches, so it might help.

Unfortunately I can’t update it just yet. But actually I have different kmp project already updated to 1.4.10 and at first, got the same error but after rebuild with cacheKind=none it worked and later it keeps working without this flag.

It’s good to know that this might fix this issue though! Thank you 🙏
