Swift 5: Use of undeclared type 'TKTransitionSubmitButton'

[kirthisamson]

Hello,
Thanks for this amazing library.

I wanted to try it out and for the life of it, I am unable to get it to work. I get his error from XCode in my Viewcontroller after linking the button from the storyboard.

Use of undeclared type 'TKTransitionSubmitButton'

I have also tried the only code mode. I get the following error at the import import SubmitTransition

No such module 'SubmitButton'

The readme does say it supports Swift 5 so I am wondering what could be the issue.
I am using the following link in my podfile

pod 'TKSubmitTransition', :git => 'https://github.com/entotsu/TKSubmitTransition.git'

More details:
