Remove or uninstall library previously added : cocoapods

I added an external framework via cocoapods into my iOS application. How can i remove that library from the project?

How do I delete a library from pod?

Just rm -rf that pod's folder, and remove the line from the Podfile. Then run pod install again.

Can you delete Podfile?

If you want to remove a Pod, edit Podfile, delete the Pod you want, and rerun pod install .

Remove lib from Podfile, then pod install again.

The unwanted side effects of simple folder delete or installing over existing installation have been removed by a script written by Kyle Fuller - deintegrate and here is the proper workflow:

Install clean:
```
sudo gem install cocoapods-clean 
```
Run deintegrate in the folder of the project:
```
pod deintegrate 
```
~~Clean~~ (this tool is no longer available):
```
pod clean 
```
Modify your podfile (delete the lines with the pods you don't want to use anymore) and run:
```
pod install 
```
