Context:
I needed to integrate Fondy payment system in the app I currently work for, but all the documentation was the link to the Example project written in Objective-C: https://github.com/cloudipsp/ios-sdk .
I decided to rewrite it in Swift to understand the idea, so I could use it for my work.
I realized that it might be helpful for other developers like me who will have to integrate it to their Swift projects.
Disclaimer:
I am not affiliated with Fondy in any way. I just had to work with their system for the job.
