To run the example project, clone the repo, and run pod install from the Example directory first.

To create a UTI use following syntax:

UTLIdentifier.JPEG

You can still use MobileCoreServices constants:

UTLIdentifier(kUTTypeJPEG)

You can also use you very own UTI:

UTLIdentifier("public.jpeg")

Or you can declare key yo use it everywhere without copypasting:

public extension UTLIdentifier {
    public static let myVeryOwn = UTLIdentifier("my.very.own.id")
}

let id =  UTLIdentifier.myVeryOwn

Instead of using MobileCoreServices methods UTLitght provides more lightweight interface.

To know whether an UTI declared:

UTLIdentifier.appleScript.isDeclared

To know whether an UTI dynamic:

UTLIdentifier.appleScript.isDynamic

To get a preferred MIME-type:

// Normally you write one-line code. 
// Two lines are for better understanding, that MIMEType is a special raw reprewentable structure
let type = UTLIdentifier.JPEG.preferredMimeType
let stringRepresentation = type.rawValue

To get a preferred file extension:

let fileExt = UTLIdentifier.JPEG.preferredFileExtension

You still have full power of original MobileCoreServices, because every computed vars and methods are fully relied on the system framework and just wraps it's not very handy syntax.
