ok. this might work if you follow the directions for re-natal and re-navigate.

and you'll have to change in index.ios.js (possibly some equivalent in index.android.js)

require('figwheel-bridge').withModules(modules).start('$WHATEVER','ios','localhost');

to

require('figwheel-bridge').withModules(modules).start('flierplath','ios','localhost');

if you're lucky, all you'll have to do is the re-navigate instructions. i.e. yarn, re-natal, etc. maybe you'll get lucky! or i can get you set up.
