Missing files libresolv.9.dylib and libxml2.dylib

SleepyViking's answer in this thread provides a shortcut to find missing .dylib files.

1. Go to Build Phases > Link Binary with Librairies > + > Add other
2. Once in the file selection window do "CMD"+Shift+G (Go to folder) and type /usr/lib/
3. From /usr/lib you can add : libz.dylib and more...
4. Compile and have fun

With the new Xcode and new iOS the links with the libresolv.9.dylib and libxml2.dylib must be updated removing the reference from Target->Building Phases and adding the new files: the files are now in a different folder:

/Users/yyyyyy/Library/Developer/Xcode/iOS DeviceSupport/9.0 (xxxxxx)/Symbols/usr/lib

where yyyyyy is the user name and xxxxxx the iOS bulild.
