#4 [master->master] iOSGiphyCodeChallenge

In this PR, you will see my code for the iOSGiphyCodeChallenge. Using SwiftUI, Combine, AsyncAwait and implemented some UNIT tests. Handled the caching with Storage. I deleted the initial project setup for this purpose. Currently SwiftUI doesn't support a good way to show GIFs except WebKit which is fully native, but I don't think this is the right approach, instead I used native SwiftyGif. Hopefully you like my solution. And for running this code you will need xCode 13.2
