title: How can I strip symbols from my iOS framework?
body: <p>I have built an iOS framework (release) but when I 'nm'/'otool' it, I see symbols I don't want to be exposed. And that are local symbols (no need to have them exported).</p>
  
  <p>As an example:
  I extract the arm64 part using lipo.
  And I see what symbols are exported in the binary using "nm -G myLibrary".
  I get a lot of:
  _kMyLibraryPrivateKey
  _MyLibrarySecretThing</p>
  
  <p>I tried to use "strip -x MyLibrary -o MyLibraryStripped", I get no error but the binary is still the same size and I get the same result with the 'nm' command.</p>
  
  <p>Why is not doing anything? how can I remove all these symbols from my framework and only keep the one that are needed by apps using it?</p>
  
  <p>Any help welcome!! Thanks!</p>
