I'd recommend just comparing the last state of the ios branch with the
base commit at the time of Dan's last merge, i.e.
9e662f2334fd9b8eab927e0e1a2bf450de8c1392. The diff doesn't look as
overwhelming as the commit list.

Then reapply the changes to the current LDC code one by one by finding
the respective code locations.
