Carthage support

[TofPlay]

Hi,
For iOS projets it's will be great to make your component Carthage compatible

Take a look at these articles:

• Ruthlessly Simple Dependency Management with Carthage
• Carthage Tutorial: Getting Started
• Making Carthage-compatible Frameworks with Swift
• Swift Cross Platform Framework (section Configure targets for Carthage) 👍

On your README.md add on top and add section for the installation with Carthage.

@TofPlay Thanks for your suggestion! I'll make sure to add Carthage support along with the new CocoaPods update.

Dear @TofPlay
Unfortunately, I cant find https://github.com/TofPlay/SwiftCrossPlatformFramework anymore. I used a bunch of your great tutorial to create such frameworks and wanted to migrate them to SPM and looks like that those tutorial have been removed.

I would appreciate you a lot if you can help me with restoring those tutorials.
