GitLab is used only for code review, issue tracking and project management. Canonical locations for source code are still https://gitweb.torproject.org/ https://git.torproject.org/ and git-rw.torproject.org.
Could we link to the iOS FAQ from https://www.torproject.org/download/? Maybe an option like "Looking for Tor on iOS?"
Thinking this would help guide a iOS user in the right direction so they don't blindly search the app store.
