Im making a game in Unity 2019, I export to iOS, then open with Xcode 11.6, made all the signing process, but when I want to build it I get:

and here is the full description:

I tried:

Removing the folder DerivedData
Cleaning the solution Removed
UnityAds from Unity (but still present on Xcode)
Looking for "Other Linker Flags" and remove "-ObjC" as most answers said, but "Other Linker Flags" was empty.
Locking GoogleAdsDependencies.xml as shown: https://answers.unity.com/questions/1355562/arm-64-function-not-4-byte-aligned-build-failed.html

As this looks like problems with UnityAds as most of the names in the logs suggests here is another post that might help you solve this: https://forum.unity.com/threads/ld-3-duplicate-symbols-for-architecture-arm64.860209/#post-5759587 — Tomasz Juszczak, Sep 10 '20 at 15:08
And another thread with a different idea: https://stackoverflow.com/questions/39512823/duplicate-symbols-for-architecture-arm64-after-xcode-8-0-update Hope any of this will help — Tomasz Juszczak, Sep 10 '20 at 15:10

I have the solution! It was the Google Unity Ads mediation plugin. So I removed the plugin and the issue is gone. How to get the plugin without the error? In the dependencies xml match the version of UnityAds that Unity is using. That's it.
