title: React Native iOS: undefined symbols for architecture
body: <p>I know there are quite a few threads about this, but none seemed to help for me so far. My problem is i am getting a linker error for debug builds: <code>Undefined symbols for architecture arm64:</code>.</p>
  
  <p>I used to have the opposite problem of duplicate symbols when trying to archive (debug was working then), i then noticed and removed duplicate dependencies manually linked and mentioned in my podfile (namely a lot of react native <code>RCT...</code>). Afterwards i was able to archive, but not to debug build anymore.</p>
  
  <p>I tried a lot of different solutions, but i am still getting the same error. I have <code>CxxBridge</code> included in my podfile, i do <code>clean</code> before i try any of the solutions. But still no luck so far. This is very annoying at the moment. Does anybody have an idea?</p>
