iOS on Rails - Library not found for -lPods

I’m not sure if the correct place to post this, but I’m running into an issue when trying to build the application in the iOS on Rails book. I’m completely new to iOS development so I’m very lost with this error. Can anyone assist?

I’m getting this error the first time it has me run the application in this section ios-on-rails/map_view_controller.md at master · thoughtbot/ios-on-rails · GitHub

It looks like you haven’t installed the Pods (the dependencies). Make sure you have CocoaPods installed (http://cocoapods.org/) and then run pod in the terminal while in the project directory. This should install all the missing dependencies and create a workspace file that you should use instead of the project file when opening the project in Xcode. When you open the workspace you will see 2 projects: the Humon-iOS and Pods. Run the project and it should work fine. Let me know if you have any other errors or if any of the steps above are unclear.

I ran pod in the terminal in the project directory and received this output

I don’t see a Pods project, but I do see Pods.xcoconfig and Pods-Humon-iOSTest.xconfig in my

That’s perfect. After that output it should create a .xcworkspace file. Open that file in Xcode instead of the .xcodeproj file. Use the workspace file for development after that. No need to open the project file anymore. When you open the workspace file you will see the 2 projects, the second one being the Pods project.

That did it. Thanks.
