Add Swift Package Manager support

[ChrisPearce]

It would be very helpful if Swift Package Manager was supported by including a Package.swift file.

Is there a timetable when the support will be added?

We need this badly as well :(

I can't wait to have the library moved to the swift package manager!!!

Any update on plans for supporting Swift Package Manager. We are taking a dependency on this library and would like to support folks using Swift PM.

Please add this!

We could use some community help with this one :) I did some experimentation and it seems difficult to get it working considering we're heavily using prefix files and nested folders. Would appreciate any references of a successful example of SPM for Objective-C library without refactoring project structure too much, or examples of getting header search working with nested folders. Feel free to directly contribute as well.

@oldalton Hi, I think Realm could be a good example of a library which is available via SPM and is written in Obj-C also. I hope it helps.

Any update on this? This is critical
