When I set my Xcode debug format to *DWARF with dSYM files,* I get thousands of warnings of this type:

`warning: (x86_64) could not find object file symbol for symbol _kfun:kotlinx.atomicfu#atomicArrayOfNulls(<http://kotlin.Int|kotlin.Int>){0§&lt;kotlin.Any?&gt;}kotlinx.atomicfu.AtomicArray&lt;0:0?&gt;`

Does anyone faced this issue before when using kotlin multiplatform on IOS?

I am having it did you find solution so far ?

+1 - We are also finding that having this high number of warnings is killing performance of Xcode.  We started noticing it after upgrading to Kotlin `1.4.30`, but not sure if this is significant.

<@U3KSUBMEU>
```GCC_GENERATE_DEBUGGING_SYMBOLS = NO;```
is what you looking for

Thanks <@UQF5Q0QHG> but these debugging symbols normally do serve a purpose in _Debug_ builds - I wonder why this became a problem with Kotlin `1.4.30` for us, when it wasn't before?

Well apter searching couple of days for this solve this issue I had only 2 solution:
• Debug information format `DWARF with dSYM File` to `DWARF`
• Second one is the one I shared
First option is messing up reporting crash logs to Crashlytics, so i continued with the one I shared to you. Please let me know also if you find something better :slightly_smiling_face:

Sure <@UQF5Q0QHG>, thanks for the extra info.  I will let you know if I learn anything new.

Hello :wave: I am also facing this issue after  the Kotlin `1.4.30` upgrade. Have you all found any more solutions other than those mentioned above?
