iex(1)> :observer.start
** (UndefinedFunctionError) function :wx_object.start/3 is undefined (module :wx_object is not available)
    :wx_object.start(:observer_wx, [], [])

You have to uninstall erlang and install wxmac, after that install erlang again.

asdf uninstall erlang <VERSION>
brew install wxmac
asdf install erlang <VERSION>

Just for completeness, in case you are using MacPorts like I am, the following command fixed the error above for me:

sudo port install erlang +hipe +ssl +odbc +wxwidgets
