Now building with Swift 5 and updated README.md

[OscarGorog]

CropViewController is now being build with Swift 5. Also, the README.md now includes all examples in Swift.

Thanks!

Oh nice! Thanks for the PR @OkiRules!

Uhhh, this commit log is a bit of a mess though. GitHub is saying 95 files were changed. How did you do that? 😅

Sorry! I'm not that experienced with Pull Requests! 😅
I hope that all the changes are OK though...

Thanks!

Probably automatic conversion ?! Can you merge this?

Looks like you need to change file mode from 755 back to 644.

Okay! I had some time free this weekend so I managed to go through this PR and cleaned it up.

I made sure your commits remained intact @OkiRules, so your GitHub account now shows you're a contributor to this project. :)

There's still a few more PRs I need to go through, so I'll do a new release when they're finished.

Thanks again for the help!
