A tutorial tells me to run pod install in the project directory. Can anyone tell me how to do that?
Open Terminal.
If you haven't already done so, run this command:
sudo gem install cocoapods
Wait for it to finish before proceeding.
Find the project directory in the Finder. This should be the folder that has the Xcode project in it.
Type cd into the terminal, followed by a space.
Drag and drop the project directory into the terminal window. It should now say something like this:
cd /Users/someone/Downloads/WonderfulProject
Press return.
Now type pod install. Wait for that to finish. It could take a while.
Done!
