Swift Package Manager support

[elsesiy]

Hi,

as this beautiful library already supports Cocoapods and Carthage it'd be great to have support for the Swift Package Manager too. Is that something you'd consider adding soon? Otherwise I'm happy to make the changes and submit a PR.

Cheers!

Hey, thank you :) A PR would be great actually. I have some other feature requests I am working on. If you don't get a chance to send one over, I will get to it soon. I placed it on the project board. Thank you.

@DanielDahan I just started working on that just to find out that SPM still doesn't fully support iOS (you're relying on UIKit a lot). The initial issue has been discussed here and has been picked up by many repositories, i.e. CocoaPods. I guess we just have to wait until support is added...

[daniel-jonathan]

Yeah, I hope support does come soon. CocoaPods is common for iOS packages in general pre swift. I will close this for now, and when there is support, we can make it happen :)
