Cocoapods setup stuck on pod setup command on terminal

This might be due to the http://blog.cocoapods.org/Repairing-Our-Broken-Specs-Repository/ issue... You will have to remove the repo and re-setup it...

pod repo remove master
pod setup

worked for me

Answered in below question as well, Error on pod install

It is not stuck. I thought the same until I went to the "Activity Monitor" of the system and checked the "Network" tab.

Then you will see that something is being downloaded. A process called git-remote-http is in charge of this.

Just wait! It happened the same for me :)

Good luck!

To get a progression, you can clone master yourself:

pod repo remove master
git clone https://github.com/CocoaPods/Specs.git ~/.cocoapods/repos/master
pod setup
