Why UIDocumentMenuViewController does not accept kUTTypeText?

Question

I saw in this tutorial and also in Apple docs, that this bunch of code should work.

let d = UIDocumentMenuViewController(documentTypes: [kUTTypeText as NSString], inMode: .Import)
o.delegate = self
self.presentViewController(d, animated: true, completion: nil)

But I get a compile time error

kUTTypeText is defined in the MobileCoreServices framework, so you should add

import MobileCoreServices

Also, as Bartłomiej correctly noticed, the type identifier has to be converted from CFString to String in Swift 2/Xcode 7:

UIDocumentMenuViewController(documentTypes: [kUTTypeText as String], inMode: .Import)

for Swift you need to cast it also: documentTypes: [String(kUTTypeText)]

@BartłomiejSemańczyk: You are right (one of the many things that constantly change between Swift releases :) – Thanks for the feedback.

@MartinR Thank you, What a big shame that this essential information "import MobileCoreServices" no where on apple documentation!

Android Studio would offer to automatically add the required imports in such cases 😱
