@shaun-mahood I kept it almost identical to the default project.clj generated by re-natal

I think I need to replace :figwheel true with :fogwheel {...}

@misha: Try adding :figwheel {:nrepl-port 7888} just above :profiles and see if that works - that's how I have mine configured, and looking at https://github.com/bhauman/lein-figwheel/wiki/Configuration-Options I think it should work (if it doesn't at least we'll find out quickly).

that'd be "server-side" place to add it

Configurations happens in your project.clj file and is separated into
 serverside configs (:figwheel {...} on your "root" level)
 and per-build, or client side, configs (:cljsbuild {:builds [{:figwheel {...}}]}).

Yep. If I understand correctly it would then apply to any per-build configs.

but Bruce mentioned something about "FW configs merge will not happen if FW is launched from (n?)REPL, something something"

Not sure about that - the global config works for me. You don't really have much of a per-client config anyway, so it may not matter either way.

got a startup idea: project.clj explainer. splits p.clj into tools' cfg maps

ok, start-figwheel! did not see [:cljsbuild :builds] inside :profiles. "fixed" with

(let [dev-builds (->> "./project.clj" slurp read-string vec (#(subvec % 3)) (apply hash-map) :profiles :dev :cljsbuild :builds)
      ids (mapv :id dev-builds)
      cfg {:figwheel-options {}
           :build-ids  ids
           :all-builds dev-builds}]
  (start-figwheel! cfg)
  (cljs-repl "ios"))
