Update pod for your project

If you directly apply the command pod install then some time new pods will not be updated in your project. For that you have to remove that specific pod information from the pod file and you have to apply pod install command. It will remove pod from the project. After that again you have to add the pod information in the pod file. Again you have to apply pod install command to install new version of pod.

Follow the next steps:

1. Remove SomePod from the Podfile

2. Run pod install

pods will now remove SomePod from our project and from the Podfile.lock file.

3. Put back SomePod into the Podfile

4. Run pod install again

This time the latest version of our pod will be installed and saved in the Podfile.lock.

You can update single pod file as follows:

Remove all CocoaPods from a project

Install CocoaPods deintegrate and clean commands from terminal.

Now you have to apply both command to remove all CocoaPods from your project:
