I am trying to create a Podfile for my Xcode project for Firebase compatibility, but when I try to create it within the same file that my Xcode project is stored in, using my terminal and typing "pod init", it throws the error "-bash: pod: command not found".
I am up to date on OSX as far as I'm aware, using Sierra 10.12.1, but I am unfamiliar with the use of Podfiles, so any help here would be great, thanks.
Looks like you didn't install CocoaPods.
To do that you install it through ruby gems, like this:
sudo gem install cocoapods
If you don't have admin privileges, try:
gem install cocoapods --user-install
