idb is made up of 2 parts, each of which needs to be installed separately.

idb companion​

Each target (simulator/device) will have a companion process attached allowing idb to communicate remotely.

The idb companion can be installed via brew or built from source

brew tap facebook/fb
brew install idb-companion

Note: Instructions on how to install brew can be found here

idb client​

A cli tool and python client is provided to interact with idb.

It can be installed via pip:

pip3.6 install fb-idb

Note: The idb client requires python 3.6 or greater to be installed.

Make sure both parts of idb are installed successfully and then you're good to go! Head over to the guided tour to try idb out.
