Updated with error message below original post.

Original post: I have a Swift project with following Podfile. Running 'pod install' in project folder does not create a .xcworkspace file and does not install any of the Pods.

I followed all instructions in 'Get Started' section of https://cocoapods.org, but still nothing.

What am I doing wrong? Running Xcode 12.1 on latest release of macOS Big Sur Public Beta.

target 'FY' do use_frameworks! pod 'Firebase/Core' pod 'Firebase/Messaging' pod 'FacebookCore' pod 'FacebookLogin' end

Update with error message: Clearly, Cocoapods are not getting installed due to issues /usr/bin. I used sudo gem install cocoapods --verbose to get the following error message. Also installed Command Line Tools for Xcode 12.1 and 12.2 from Developer Portal.

Initialize cocoapods

The first time you need to run pod init in your projects directory to initialise your project.

It will create the new xcworkspace AND pod file. Once this is done add your pods to the pod file and run pod install

Make sure the deployment target of your xcode project and the platform in the pod file are the same. For example ios 14.1.

Install pods

If you want to add more pods, add them to your pod file and run pod install in your project directory again.

Update pods

If you want to update all your pods run pod update in your project directory.

Removing individual pods from project

Just delete the line from the pod file or comment it out and run pod install in your project directory again.

Removing cocoapods from project

In some cases it might be necessary to completely remove cocoapods from your project. Run the following in your project directory.

pod deintegrate

pod cache clean --all

rm Podfile

If you are trying to reinstall it only, try pod deintegrate only, leaving the pod file and cache intact. Followed by pod install. If this doesn't work use all three commands above and start from the beginning.

You might have to install pod deintegrate and pod clean if you haven't done so yet. Run sudo gem install cocoapods-deintegrate cocoapods-clean to do that.

Installation notes

Make sure cocoapods is installed correctly on your system. You can use pod --version and it should give you the installed version. If it says file not found, or similar, something is wrong.

Quite often sudo gem install cocoapods has issues with the usr/bin directory permissions. It should tell you that when trying to install.

Try sudo gem install -n /usr/local/bin cocoapods instead.

If this doesn't work try sudo gem install cocoapods --verbose and have a look at the output. Usually at the very end you will see the errors that caused the installation to fail.

Use the same command you used to install cocoapods to update to the latest version.

Thank you. I get the following error for pod init. zsh: command not found: pod. I installed CocoaPods using sudo gem install cocoapods. May I need to add a path to bash profile?
I've added to my answer. Make sure to check the installation note part.
And post any errors you are getting here in the comment or your original answer and I will update my answer accordingly. The more information you can give the better and watch closely not to overlook an error. : )
Hello Marco, Thanks for your detailed response. I updated the post with error message from console.
